Wastewater treatment is an important process that is essential to protecting public health and the environment. The goal of effective wastewater treatment is to remove pollutants and contaminants from wastewater, but there are challenges the industry faces every day – including the impact of rising temperatures on wastewater treatment processes. 

Today, the impacts of rising temperatures and climate change are a growing concern for wastewater treatment. Current trends of increasing temperatures can significantly affect the treatment processes. In this article, we’re taking a look at the current state of wastewater treatment, the effects of rising temperatures, and the solutions that will help the industry adapt and overcome these impacts. 

The Current State of Wastewater Treatment 

Wastewater treatment plants are designed to remove a range of pollutants and contaminants from wastewater. Depending on the wastewater being treated and the goals, there are several methods of treatment that can be used. Rising temperatures create situations where wastewater treatment may need to be handled differently to compensate for new challenges.

The U.S. Environmental Protection Agency states that wastewater treatment centers in the United States process an incredible 34 billion gallons of wastewater every single day. As rising temperatures bring changes such as increased storms and flooding from natural disasters, this places additional stress on an already massive wastewater treatment load. On the opposite end of the spectrum are droughts, and wastewater treatment facilities adapting to the changes and challenges this creates. 

Today’s Wastewater Treatment Processes 

There are three main methods of wastewater treatment processes. These include physical, chemical, and biological treatment. Rising temperatures can impact each of these processes in different ways. 

Physical wastewater treatment involves methods that physically remove large objects and debris from wastewater. This includes contaminants such as branches, leaves, physical debris, trash, and suspended solids, like oils and greases. 

Physical wastewater treatment processes involve the use of screens and rakes to remove solid, physical waste. Rising temperatures are creating unique problems with physical treatment. 

For example, higher temperatures can make it more challenging to remove suspended solids from wastewater and decrease the efficiency of processes to remove sedimentation. Sedimentation is the process of allowing wastewater to sit in a tank or basin until the suspended solids settle to the bottom where they can be more easily removed so that the wastewater can be further treated. 

Chemical treatment involves using certain chemicals to remove pollutants and contaminants. Rising temperatures can affect both the efficiency and effectiveness of the chemical reactions involved in these processes. Rising temperatures may also increase the bacterial load of wastewater, making it more challenging to treat effectively. 

Biological treatment involves the use of microorganisms to break down organic matter and remove certain pollutants. Biological treatment processes are extremely sensitive to temperature, with higher temperatures interfering with the maximum effectiveness. 

There’s a fine line with temperature in biological processes. On one hand, elevated temperatures can increase biological reactions, but there’s a point when temperatures rise above a certain point when these reactions actually begin to decrease instead. 

Rising temps also create a situation where wastewater treatment facilities need to be more mindful of an increase in emissions, particularly hydrogen sulfide in droughts, which can have negative impacts on human health. 

How Climate Change is Affecting Wastewater Treatment Infrastructure 

Rising temperatures affect not only the processes of treatment wastewater but also the overall wastewater treatment infrastructure. Rising temperatures can lead to issues such as increased evaporation and reduced water flow, along with a higher concentration of pollutants. 

This type of general climate change can also lead to increased rainfall and flooding, which can potentially overwhelm the infrastructure of wastewater treatment facilities. This can potentially lead to the release of untreated sewage into major water bodies, creating a level of contamination that can pose a risk to human health and the environment. 

The increased frequency and severity of extreme weather events, including hurricanes and droughts, can impact wastewater infrastructure at every level. 

Fortunately, the wastewater treatment industry isn’t without solutions to these challenges. The first step has been to gain a better understanding of the effects of climate change on wastewater infrastructure. Next, has been to look at how to adapt through technology and operational changes. 

Adapting to Climate Change and Rising Temperatures with Wastewater Treatment Solutions 

Climate change is a challenge that needs to be addressed by the wastewater treatment industry without hesitation. In the short term, there is little that can be done to affect the current trajectory of climate change. However, actions taken today can impact climate change in the future. 

This means that wastewater treatment facilities need to remain flexible and ahead of the curve. Here are a few ways they’re accomplishing this. 

Advanced Treatment Technologies 

Advanced treatment technologies are changing wastewater treatment processes in a way that’s better aligned to meet the challenges of climate change. Membrane bioreactors and advanced oxidation processes are examples of this. These methods of wastewater treatment can be more effective at removing pollutants and contaminants during wastewater treatment and are more resilient to unpredictable changes in temperature and precipitation. 

As an example, membrane bioreactors use a combination of physical and biological processes to remove pollutants and contaminants from wastewater. This might include advanced membrane filtration equipment, combined with a suspended growth biological treatment. This combination makes membrane bioreactors highly effective at removing a wider range of pollutants, including nutrients, heavy metals, and organic compounds. 

The enhanced efficiency makes them a viable option for changing wastewater treatment demands. Plus, membrane bioreactors are relatively easy to integrate into existing wastewater treatment facilities, making them an attractive option from a financial standpoint as well. 

Green Infrastructure 

The wastewater treatment industry is looking at how green infrastructure can help address the challenges of rising temperatures and climate change. Green infrastructure includes elements such as green roofs and rain gardens that help to reduce stormwater runoff, and as a result, relieve some of the increasing pressure on wastewater treatment plants. 

Finding innovative, eco-friendly means of capturing, absorbing, and reducing runoff to filter stormwater delivers a range of environmental, social, and economic benefits outside of wastewater treatment. 

Green infrastructure is also a great way to build community awareness around the challenges of wastewater treatment in the face of climate change. These initiatives support sustainable water resource management and can be incorporated into urban planning, especially in communities that face specific issues, such as flooding or drought. 

Climate Resilient Design 

An important element of adapting to rising temperatures and climate change is ensuring that sewer systems and wastewater treatment facilities are designed to be resilient to the impacts of climate change. At a basic level, this includes the use of more durable materials, increased wastewater storage capacity, and efficient backup power systems for wastewater treatment centers. 

Climate-resilient wastewater treatment is a win from every angle. Even without noticeable changes in temperatures and climates, implementing resilient design leads to improved efficiency, and better water resource management, and can save facilities money in the long term. 

Currently, there is a level of hesitation from some wastewater treatment facilities to adopt these approaches. It makes sense that wastewater facilities are taking trends that they have seen in the past and adapting their processes and infrastructure to what is known. Climate change, the challenges it will bring, and how the wastewater treatment industry will be impacted in the future are still not fully known. 

However, current climate events have shown that there are inadequacies that need to be addressed, and that weather is never predictable. It’s essential that wastewater treatment facilities begin implementing climate-resilient wastewater treatment solutions today. 

Wastewater Treatment and the Future of Climate Change 

Rising temperatures due to climate change have had an impact on wastewater treatment processes and are a pressing concern for the future of the industry. Rising temperatures can affect the effectiveness of wastewater treatment systems in a negative way. However, at Lakeside Equipment, there are advanced technologies and processes that can meet these challenges and mitigate the impacts of rising temperatures on wastewater treatment. 

It’s important to take the right steps today to address these challenges for a cleaner, safer tomorrow.

Initiatives to Preserve Aquatic Life 

One of the most significant concerns with hydropower is its impact on aquatic life. Efforts to preserve aquatic life, both in existing and future systems, are a key focus. The industry is taking initiatives to address these concerns with innovations in how turbines are designed and how they function.

In the coming year, this looks like a stronger focus on hydrokinetic turbines, minimum gap runner turbines, and other turbine designs that allow for the safe movement and migration of aquatic life through areas where hydropower plants are located. 

Novel Turbines 

Different types of novel turbines are being developed to improve the efficiency and power output of hydropower plants. Innovation in this field is heavily focused on increasing flexibility through novel turbine design. The goal is to improve not only the efficiency and cost-effectiveness of hydropower generation but also the overall sustainability of the future of the industry. 

An example of this is the use of very low-head turbines, where the head is typically less than 20 meters. These turbines are ideal for placement in locations with limited water resources that previously would have been impossible, or at least inefficient, to leverage for hydropower. 

Dynamic Pumped Hydropower  

Dynamic pumped hydropower is an innovation being used to maximize energy generation and storage. With this process, the elevation difference between two water reservoirs is used to generate electricity. The system operates by pumping water from a lower reservoir into a higher one during periods of low energy demand. Then during peak periods, the energy is released to generate power. 

Dynamic pumped hydropower can help increase grid resilience and flexibility in years to come. 

Potential Challenges and Opportunities in Hydropower 

As with anything, there are both potential challenges and opportunities as the hydropower industry moves forward in 2025.

Commercial kitchens are fast-paced environments, and there are many moving parts that keep them running smoothly. Part of this is keeping the drainage system clean and functioning. Commercial kitchens deal with a significant amount of grease and food waste that presents unique challenges to keeping their drain systems healthy. One solution is hydro-jetting, which is a powerful drain-cleaning technique that has become a top choice for maintaining commercial kitchen drains. 

Here, we’re going to dive into the advantages of hydro-jetting for commercial kitchens, and why it has become one of the best solutions. 

What Is Hydro Jetting? 

Hydro-jetting is a drain cleaning technique that uses high-pressure water or steam to clean the interior surfaces of drains and pipes. A hose with a jetting nozzle is inserted into the drain system, and water is released at extremely high pressure. On average, a water pressure of about 1500 psi is used for standard treatment. However, there may be cases where more pressure is needed. In some cases, pressure as high as 5,000 psi or higher is used. 

With this high pressure, grease, debris, and obstructions are dislodged and flushed out of drains and pipes. Hydro-jetting is more effective at breaking up clogs than traditional methods like drain snaking because it completely removes build-up and residue. 

Why Commercial Kitchens Need Advanced Drain Maintenance Solutions

The sheer volume of grease and food waste handled by commercial kitchens makes drain and plumbing maintenance more complex than residential kitchens. The frequent and heavy use of fats and oils can lead to grease accumulation in pipes. This can happen even with a grease trap system if it’s not properly maintained. Over time, the accumulation of grease can harden and cause blockages in pipes. 

It isn’t just grease that’s the culprit in commercial kitchens. Food particles also play a role. Food particles from plates that have been scraped and kitchen prep areas can make their way into drains, resulting in troublesome clogs. 

In addition to this, clogged or blocked drains present problems that don’t meet stringent health regulations. For example, unpleasant odors, drainage backflow, and unsanitary conditions. Not properly maintaining drains can put a commercial kitchen at risk of being fined for non-compliance with local health regulations. 

6 Benefits of Hydro Jetting for Drain Maintenance

Preventative Maintenance 

Hydro-jetting can be used as preventative maintenance, rather than used solely for treating existing clogs. Commercial kitchens that schedule regular hydro-jetting sessions as part of their preventative maintenance schedule can prevent the buildup of grease and food debris before it has a chance to become an issue. This simple step can save commercial kitchens from costly repairs and downtime in the future. 

More Thorough Cleaning 

Snaking, which was considered the standard drain clog treatment for years, is effective at breaking clogs and increasing water flow, but it doesn’t get the job done as well as hydro-jetting. The high-pressure water of hydro-jetting removes grease, food particles, and mineral deposits from inside the pipes. This is in contrast to snaking, which works by puncturing a blockage, and sometimes breaking it loose. The thorough cleaning that hydro-jetting offers reduces the risk of recurring blockages while optimizing flow capacity. 

Gentler, Eco-Friendly Drain Maintenance

Compared to chemical drain cleaners, hydro-jetting is a safer, gentler, and more eco-friendly solution. Harsh chemical drain cleaners can be harmful to the pipes and potentially contribute to corrosion. The chemicals aren’t friendly for the environment either, with residue making its way into local sewage and water systems. 

Improved Drainage Efficiency 

Hydro-jetting is effective for increasing drain efficiency. By removing debris and buildup from inside pipes, hydro-jetting eliminates slow drainage and minimizes the risk of backups. This is key for keeping commercial kitchens operational and avoiding safety risks and disruptions to business. 

Addresses Multiple Issues with One Treatment 

Unlike other drain cleaning methods, hydro-jetting is effective for treating a wide range of blockages, and it’s suitable for various types of pipe materials. In our experience, hydro-jetting can treat blockages caused by grease, food, sludge, scale, and in some cases, small tree roots. The versatility of hydro-jetting makes it a good first option for clogs or backups of unknown origin. 

Improving Workplace Safety and Cleanliness

When a drain in a commercial kitchen is blocked or slow-flowing, it can create hazardous and unhygienic conditions. Standing water that occurs as a result of backflow can significantly increase the risk of slips and falls. In high-volume, fast-paced commercial kitchens, this becomes an even greater risk as employees might not notice the issue before it’s too late. 

Additionally, with standing water comes lingering foul odors and the potential for bacterial growth. These are not situations that should ever be associated with a commercial kitchen. Standing water compromises the hygiene of the kitchen, and puts both employees and guests at risk. 

Cost Effectiveness 

The downside of hydro-jetting is that it’s typically more costly upfront compared to other drain treatment methods. Still, even with the higher upfront costs, hydro-jetting proves to be more cost-effective in the long run. A thorough hydro-jetting cleaning reduces the frequency of repairs and emergency service calls. By keeping drains and pipes in clean, optimal condition, hydro-jetting can also extend the lifespan of the plumbing system. Overall, hydro-jetting saves money and is a smart investment for the future. 

When To Use Hydro-Jetting In Commercial Kitchens 

Hydro-jetting is versatile enough to make it suitable for various commercial kitchen drain needs. 

Recurring or Difficult Clogs: Where hydro-jetting is used most frequently to remedying clogs, especially in kitchens that experience frequent or recurring blockages. Hydro-jetting helps to address the root cause, rather than providing a quick fix or temporary solution. 

Commercial Kitchen Grease Buildup: Hydro-jetting is the most effective way of removing resistant grease deposits that can easily become problematic for commercial kitchens. 

Routine Maintenance: It’s not necessary to wait until an issue occurs before contacting a hydro-jetting professional. Commercial kitchens can benefit from including hydro-jetting in their regular maintenance schedule. For most commercial kitchens, an annual hydro-jetting service will work for preventative maintenance. Kitchens that experience frequent or recurring clogs might want to schedule a cleaning once every six months until the issue is completely resolved. 

Post-Renovations: Commercial kitchens that have recently undergone renovations or new installations can benefit from a hydro-jetting sessing. This can help clear out construction debris, such as dust and dirt, along with stray construction materials that may have found their way into the pipes. 

What To Expect with a Hydro-Jetting Session

Whether the plumbing professional is called to a commercial kitchen for a plumbing issue or routine maintenance, a hydro-jetting session typically begins with an inspection of the drain and pipes. This is done using a small camera that is inserted into the plumbing system. From here, the professional will look for the source and severity of any blockages, along with buildup, debris, and structural issues in the plumbing. 

After the initial inspection, a hydro-jetting nozzle is inserted into the pipe and a high-pressure stream of water is released. The water pressure force and duration of treatment will depend on the severity of blockages and debris. 

Once the hydro-jetting session is complete, a second inspection occurs. This is to ensure that all blockages were removed and that plumbing is in good working condition. Sometimes, after debris is removed, a plumbing professional is better able to assess the overall health of the plumbing system. If they notice any issues or have recommendations, they will state so at this time. 

Hydro-Jetting for Plumbing Longevity in Commercial Kitchens

Commercial kitchens can’t afford for their drains and plumbing systems to go down. Maintaining a functioning, efficient drainage system is something that can’t be compromised on. Hydro-jetting stands out among other options as a powerful, eco-friendly, and cost-effective solution for maintaining commercial drains.

Wastewater treatment systems are essential for their role in maintaining public health and environmental quality. The importance of wastewater treatment doesn’t ebb and flow based on the weather. Even during the harshest winter months, wastewater treatment facilities need to maintain their functionality. During winter, freezing temperatures, heavy snowfall, and icy conditions can present challenges to wastewater treatment systems and their daily operations. 

Understanding the Impact of Winter Weather on Wastewater Treatment 

Winter weather presents unique challenges to the wastewater treatment industry. These challenges can affect the operation of the physical infrastructure, as well as biological processes that are used for certain types of wastewater treatment. 

For example, freezing pipes and equipment can become an issue in sub-zero temperatures. This can lead to broken equipment and mechanical failures as the risk of freezing increases. There are also increased energy demands required to keep wastewater treatment systems operating during freezing weather. 

For wastewater treatment processes that rely on biological methods, winter weather can reduce the effectiveness. When temperatures drop, microbial activity slows down, significantly impacting the efficiency of the biological treatment process. 

It isn’t just freezing temperatures that can interfere with wastewater treatment processes. As snow melts, it can lead to excessive inflow into sewer systems. Susceptible wastewater treatment facilities may find themselves overwhelmed to the point that they’re unable to effectively treat the overflow. 

Winterization Strategies for Wastewater Treatment Systems 

While winter weather can’t be avoided, there are steps wastewater treatment facilities can take to ensure smooth operations during the winter months. Here are a few examples of effective wastewater treatment winterization strategies. 

Infrastructure Insulation: Pipes, pumps, and other outdoor equipment can be wrapped with insulation to help prevent freezing. In some cases, electric heating cables can also be used. Wastewater treatment facilities that are located in especially harsh climates can design their facilities to have their critical equipment sheltered by enclosed buildings. 

Management of Biological Treatment Processes: Wastewater treatment facilities that use biological systems can equip their treatment tanks with heating systems to maintain optimal temperatures for microbial activity. Ensuring that tanks are covered during the winter can further prevent heat loss. Even with these measures, some facilities may need to modify their treatment processes during extreme winter weather. 

Managing Overflow Infiltration: Regular maintenance and practicing effective stormwater management are smart strategies for minimizing the potential damage caused by winter overflow. Ensure that all sewer lines are in good working condition and implement a system to divert excess stormwater away from the wastewater system. 

Being Prepared for Winter Weather Emergencies: While weather-related emergencies can happen any time of year, it’s important for treatment facilities to be prepared for potential winter emergencies. This included ensuring there is a working backup power system to maintain operations during power outages and making sure staff is fully trained on how to handle extreme weather events. 

Innovations in Winter Wastewater Treatment 

When looking at how wastewater treatment facilities effectively manage seasonal operations, it’s important to also look toward new innovations and how they are improving winterization processes for the industry. 

As an example, automated monitoring systems can assess temperature, flow rate, and performance in real-time to more efficiently identify and remedy potential winter-related issues. Some facilities are also taking advantage of geothermal energy to heat biological treatment tanks and buildings. Geothermal energy is a sustainable source of energy that can be an effective cold-weather solution for facilities located in colder climates. 

Environmental and Economic Considerations for Winter Wastewater Treatment 

Wastewater treatment plants need to consider environmental and economic factors when choosing how to handle winter challenges. 

Increased energy usage is a challenge for facilities during the winter months. Winterization strategies frequently demand additional energy usage, which can place a strain on the budget, as well as cut into a treatment facility’s sustainability goals. Today, more facilities are exploring how to utilize renewable energy sources to offset the increased energy demand during colder months. 

Treatment plants also play a critical environmental role in ensuring untreated sewage from snow melt doesn’t contaminate local water sources. Treatment facilities need to have a plan in place to effectively divert snowmelt and treat it effectively before it has the chance to negatively impact the environment and local ecosystems. 

Winterization strategies can be costly for wastewater treatment plants. By investing in technology and infrastructure that is winter weather-ready year round, they can help mitigate many extra costs. While there is a significant upfront investment, these are measures that can reduce expensive repairs, winterization methods, and environmental fines further down the road.  

Preparing for a Changing Climate in Wastewater Treatment 

Wastewater treatment facilities are just focused on managing winter weather operations today. They also need to be looking toward the future, including how climate change may affect the weather, and as a result, winter operating processes. In many regions, climate change is expected to cause shifts that intensify seasonal weather. For some, this will include colder temperatures, heavier snowfall, and longer winter seasons. 

When considering how future operations may be affected by climate change, wastewater treatment plants are looking at how to upgrade their current infrastructure with modern, weather-resistant equipment. They’re also looking at how to design and implement systems that are capable of handling extreme weather conditions. With this, the industry witnesses broader global collaboration in developing effective winterization solutions. 

Final Words 

While winter weather challenges are a challenge for wastewater treatment systems, there are viable solutions being implemented across the industry.

Wastewater treatment is an essential process for preserving a sustainable water supply, protecting local ecosystems, and maintaining public health. There are many components of wastewater treatment that play a role in this. Among the most important are wastewater aeration systems. In the process of wastewater treatment, it’s the aeration systems that are the first line of breaking down organic matter and reducing contaminants. 

Here, we explore the critical role of aeration systems, the different types used in wastewater treatment, and their benefits for today’s wastewater management. 

The Role of Aeration in Wastewater Treatment 

In the simplest terms, aeration is the process of introducing air into wastewater. This is essential to the biological decomposition of organic pollutants by various microorganisms. Aeration supports bacteria that thrive in oxygen-rich environments, where they work hard to metabolize organic matter. The process results in the matter being broken down into compounds such as carbon dioxide and water. 

In addition to ensuring wastewater has enough oxygen to support aerobic microbial activity, aeration also promotes a more even distribution of oxygen, microorganisms, and nutrients throughout the wastewater being treated. With effective aeration, wastewater treatment facilities are able to increase treatment efficiency and prevent environmental contamination. 

4 Types of Aeration Systems for Wastewater Treatment 

There are four main types of aeration systems used by wastewater treatment facilities. Each type of system is designed to meet very specific needs and wastewater treatment operational conditions. A professional wastewater treatment equipment provider can work with a facility to identify their needs and find the best aerator for their water purification processes. 

Surface Aerators 

Surface aerators are devices that agitate the surface of the, introducing oxygen into it. These are most commonly used in lagoons and aeration basins. Surface aerators are often preferred for their portable, simple design that just sits at the surface of the water. They are extremely easy to install and simple to maintain. 

The downside of surface aerators is that they are less efficient at introducing oxygen than other types of aerators, especially when used in deeper banks. They are highly efficient in shallow waters, but their capacity beyond this is more limited. Surface aerators can also suffer some challenges in climates with colder temperatures. 

Subsurface Aerators 

Subsurface aerators work below the surface of the water and release small air bubbles from the bottom of the tank. These small bubbles rise throughout the water to provide oxygen to microorganisms, which then work to break down all of the organic matter. Compressed air is delivered by an air pump that is connected to diffusers on the ground of the tank. Subsurface aerators are highly efficient at oxygen transfer and are often the aeration system of choice for activated sludge systems. 

The downside of subsurface aerations is the higher initial costs and more frequent and complex maintenance requirements. 

Jet Aerators 

Jet aerators are more complex systems that combine air injection with a pump mechanism to more efficiently mis the water and introduce oxygen. Due to the mechanisms through which jet aerators work, they are highly effective in industrial applications where high wastewater treatment loads are common. When comparing all types of aeration systems, it’s jet aerators that provide the highest level of mixing and aeration capabilities. 

Hybrid Systems 

Hybrid systems are multi-purpose aeration tools that integrate more than one type of aeration technology to optimize overall efficiency. Hybrid systems are well-suited for wastewater treatment facilities that have variable treatment needs. Of all the aeration systems, these are the most versatile and adaptable. With this comes more complexity than other types of systems, and are generally more costly. 

Benefits of Aeration Systems 

We know that aeration systems infuse the wastewater with oxygen to feed crucial microorganism populations. It’s also important to look deeper at the multifaceted benefits that contribute to both environmental health and wastewater treatment operational efficiency. 

More Efficient Organic Matter Removal: Organic matter removal is a critical component of wastewater treatment. Efficient organic matter removal prevents the depletion of oxygen and, more importantly, protects water quality by removing harmful byproducts. Aerations expedite this process, which is key to improving water quality in the most efficient way possible. 

Odor Management: Wastewater treatment can create unpleasant odors. Aeration systems that support aerobic water conditions are helpful in reducing these odors by reducing the production of pungent-smelling gasses. 

Reduction in Pathogens: Aeration systems are among the most effective means of reducing the population of dangerous pathogens. By supporting beneficial microbial activity, wastewater aeration systemically reduces disease-causing microorganisms. 

Compliance with Regulatory Guidelines: Wastewater treatment facilities are in a position where they are required to meet strict regulatory standards. The efficiency of aeration systems helps wastewater treatment facilities more efficiently meet these strict guidelines and water quality standards. 

Challenges of Aeration Systems in Wastewater Treatment 

Wastewater treatment aeration systems offer many benefits. However, there are also challenges that wastewater treatment facilities should be aware of, especially in areas of impacted efficiency and longer-term viability. 

Higher Energy Requirements 

Aeration systems are energy-hungry. They consume large amounts of energy resources to function optimally. As a result, they are often a significant portion of a treatment facility’s overall energy usage. This makes aeration systems a major contributor to overall operational costs. This might not be as much of an issue for larger treatment plants, but this can significantly cut into the budget of smaller operations. 

Clogging and Inefficiencies 

Even the most efficient aeration systems are prone to occasional clogging and inefficiencies. There are issues with biofilm, scaling, and debris that can significantly reduce function and efficiency. Treatment facilities should train staff members on how to identify clogs and inefficiencies in aeration systems and how to remedy them.

Maintenance 

With clogging and inefficiency comes a higher level of maintenance. Wastewater treatment facilities should be prepared to regularly monitor key components like motors and diffusers. These components require regular upkeep and often more frequent maintenance for optimal efficiency. Skipping out on maintenance of wastewater treatment systems can lead to more costly repairs down the road. 

Environmental Concerns

While aeration systems work to clean wastewater, which is critical to protecting the environment, they can also cause a level of environmental damage in other ways. For example, their high level of energy usage contributes to a larger carbon footprint. 

Innovations in Aeration Technology

With aeration being such an effective tool in wastewater treatment, we’re excited to look forward to how aeration systems will reshape treatment processes in positive ways. On the horizon, we see aeration systems that are even more efficient and environmentally friendly, requiring less in terms of energy consumption. For new systems, this can include smart control mechanisms and enhance oxygen transfer rates. Fine pore diffusers and high-efficiency blowers are examples of technology that are making aeration systems less energy-dependent and more efficient. 

Low-energy hybrid designs and systems with automated controls that adjust oxygen levels based on real-time need are making aeration something that is less of a financial stress on smaller wastewater treatment facilities.

Aeration in Wastewater Treatment Now and Into the Future

Preventative maintenance helps to protect all system components, extending the overall lifespan of the equipment. 

Environmental Considerations of Regularly Wastewater Treatment Maintenance

Yes, regular maintenance is essential for optimizing production and efficiency and reducing repair costs. Still, we don’t want to ignore the environmental benefits of proper maintenance. 

Properly maintained wastewater treatment systems ensure that treated wastewater meets current environmental standards. This includes preventing pollution of local natural water sources and protecting local wildlife. Properly functioning equipment also reduces overall water and energy usage. 

Preventative Maintenance Strategies for Wastewater Treatment Facilities

Wastewater treatment facilities can take a proactive approach to maintenance. By adding a few proactive maintenance steps to regular operations, wastewater treatment staff can help reduce the risk of equipment failure while extending the life of wastewater treatment equipment. 

Set a Maintenance Schedule 

A regular maintenance schedule for all equipment should be followed. The schedule should be based on manufacturer recommendations, but it’s also important to consider operational conditions. A wastewater treatment center that is experiencing higher than typical processing will want to increase the frequency of regular maintenance checks. 

Regularly Monitor Wastewater System Performance 

Systems should be monitored daily for key performance parameters. Daily monitoring should include flow rates, pressure, and chemical levels as applicable. 

Provide Training to All Staff

Managers of wastewater treatment facilities should ensure all staff is trained on maintenance protocol and how each system operates. They should be able to identify and troubleshoot issues with the equipment they work with. All staff should be invited to a training session each time there are updates or new technologies implemented in the wastewater treatment system. 

Maintenance Challenges and How to Overcome Them 

In the best of times, all wastewater treatment runs smoothly and efficiently without issue. However, even with a proactive approach there are challenges that exist. Here are a few of the most common maintenance challenges wastewater treatment centers face. 

Inconsistency with Recordkeeping: Proactive and regular maintenance are key to keeping systems operating at optimal capacity. It’s also equally important that all maintenance activities are documented. Failure to properly document leads to staff resources being used inefficiently by repeating tasks, or missing tasks and inspections completely. Digital tracking systems are an effective way of eliminating this challenge and providing a clear record of maintenance for all equipment. 

Budget: Smaller wastewater treatment facilities can face the challenge of budget constraints limiting their ability to perform regular maintenance tasks. Putting off even small maintenance tasks significantly increases the risk of costly system failures later down the road. The long-term cost savings make regular maintenance something that should be factored into the budget, regardless of how large or small. 

Absence of Maintenance Inventory: Wastewater treatment facilities should keep at least a baseline inventory of replacement parts for critical components. Without this backup inventory delays in repairs can happen, increasing the risk of system failure. Keep essential spare parts, such as seals, filters, and gaskets on hand to minimize lengthier downtimes while waiting for parts to arrive. 

Factoring In the Environment: Even when facilities follow suggested maintenance schedules it might not be enough. Harsh operating environments, which include exposure to extreme weather conditions, the use of corrosive chemicals, or exposure to abrasive materials can accelerate normal wear and tear on equipment. Facilities that operate under more extreme conditions adjust their maintenance schedule to reflect these challenges. 

Advanced Maintenance Innovations  

Today, we’re seeing the use of advanced technologies improving the efficiency of wastewater treatment maintenance. 

Predictive maintenance is one example that uses sensor data and analytics to provide anticipated timelines for when equipment will require maintenance. There are also remote monitoring systems that provide real-time analysis of system performance. This is especially beneficial for facilities that experience challenges in adhering to maintenance schedules.  

Developing a Maintenance Checklist 

One way for wastewater treatment facilities to ensure that preventative maintenance tasks are completed is by creating a maintenance checklist. Checklists will vary depending on the facility’s needs, but a general template will look something like this:

Daily Tasks: Check general performance metrics, including pressure and flow rate. Inspect key components such as pumps, blowers, and tanks for any obvious issues. 

Weekly Tasks: Actions like cleaning filters and screens should take place at least weekly. Add additional tasks such as removing sludge from tanks. 

Monthly Tasks: Conduct a more in-depth analysis of equipment health and performance. Test backup systems and ensure emergency generators are in working order. Sensors should also be assessed and calibrated monthly. This is also a good time to ensure that all current staff have been properly trained on maintenance procedures.

Quarterly Tasks: Gaskets and seals should be checked quarterly and replaced if any signs of wear are showing. Add checking system piping to the quarterly tasks list, including scheduling any professional maintenance appointments for tasks that can’t be handled by in-house staff. Check inventory to ensure adequate backup components. 

Annual Tasks: At least once a year, perform a comprehensive assessment of equipment performance. Assess whether any equipment is showing significant signs of wear or performing less than efficiency. All maintenance schedules should be updated annually, as well as updating all team members on any changes. 

Conclusion

Proper maintenance of wastewater treatment equipment is a critical component for efficient operations and regulatory compliance for treatment centers. Knowing how to properly maintain equipment, setting a comprehensive maintenance schedule, and taking advantage of the many advanced tools available are all keys to ensuring optimal performance.

When we talk about plastic pollution, the image is typically of landfills overflowing with plastics or harmful plastic bottles and bags floating in the ocean. This represents the tangible type of plastic pollution that we can see. However, there is an entire world of plastic pollution that exists beyond what we can touch or see. This is the world of microplastic pollution, which are minuscule plastic pieces that find their way into our water systems, and environment. The microplastic problem is substantial, but microplastic filtration in wastewater treatment is one way we can begin to tackle it. 

What Is Microplastic Pollution?

Microplastics are just as they sound – small bits of plastic, usually smaller than a single grain of rice, that come from various sources. There are some types of microplastics that appear to be pollution in their whole form. An example of this is the small microbeads that are popular in facial and body scrubs. These are an especially big problem for pollution due to how they are washed down drains when they are used. Eventually, they flow into wastewater treatment plants. 

Other sources of microplastics are called secondary microplastics. These are formed by the degradation of larger plastic items. For example, a plastic shopping bag that has shredded or torn, leaving small pieces of plastic behind. Secondary plastics can also easily make their way down drains and sewage systems, eventually landing in wastewater treatment plants.

If microplastics make it past wastewater treatment plants, they can more easily end up in rivers, and oceans, and eventually into our food chains and bodies. Wastewater treatment plants play an important role in managing microplastic pollution. 

The Role of Wastewater Treatment Plants in Microplastic Pollution

We like to think of wastewater treatment plants as the guardians of our water quality. On both small and large scales, these facilities process a vast amount of debris and pollutants in the water. This includes a mixture of physical, biological, and chemical pollutants, including microplastics. 

Wastewater treatment facilities are designed to capture pollutants and impurities while using different purification methods based on the type of pollutant. For larger debris, such as sticks, leaves, and other organic debris, equipment such as trash rakes are highly effective. However, microplastics pose different challenges due to their small nature. Systems designed to capture larger debris aren’t always efficient at filtering out microplastics. 

We’re at a critical point when it comes to removing microplastics from our waters. It’s estimated that by the year 2050, the amount of plastic in the sea will likely outweigh the fish. Addressing microplastic pollution at wastewater treatment facilities is one of the most important steps for reducing the impact of microplastics in our local and global water sources.  

Current Methods for Microplastic Filtration in Wastewater Treatment 

The type of filtration used depends on the type of microplastics and their source. There are a few ways that wastewater treatment facilities can tackle the microplastic problem. 

The first is through primary treatment. This is used for pieces of plastic debris that can be filtered out with screens and similar types of equipment. Primary treatment is effective at capturing larger pieces of plastic debris and microplastics that are at least a few millimeters in size. Primary treatment isn’t as efficient for capturing smaller microplastics. 

Biological treatments can be used to target the smaller particles. This type of treatment helps capture plastics using attached or suspended growth systems. After this stage, the final step is the chemical treatment, which helps to disinfect and filter microparticles from the water. 

Challenges in Microplastic Filtration 

One of the biggest challenges in microplastic filtration is detection. Microplastics come from so many different sources, that detecting their presence isn’t a straightforward process. Relatively larger microplastics are captured with rakes and screens, but smaller particles are much more difficult to detect and filter. Unfortunately, it’s these smaller particles that often pose a more significant threat to the integrity of water sources and wildlife. 

Cost and infrastructure present additional challenges. The industry is evolving to the point where technology is making it possible to detect and remove smaller microplastic particles. However, retrofitting wastewater treatment centers with new equipment is expensive. The ability of the industry to tackle microplastic pollution is heavily reliant on the ability of individual treatment centers to adapt and absorb the costs. 

Secondary pollution is also an issue. During the filtration process, some microplastics may end up in organic waste that has been filtered from wastewater. Sometimes, this waste is used for fertilizer or recycled in other ways. If microplastics are present in this waste, there is a higher chance of them leaking back into the environment. 

Benefits of Effective Microplastic Filtration in Wastewater Treatment 

The benefits of wastewater treatment facilities being able to effectively filter microplastics are extensive. Microplastics are a growing issue, both for our personal and environmental health. The first step is for each of us as individuals to reduce the amount of microplastics that enter water systems. However, it’s wastewater treatment facilities that serve as the true heroes. 

When microplastic pollution is addressed at wastewater treatment facilities, all of us are able to benefit from the results. 

Cleaner Environment: The more efficient we become at filtering microplastics, the better able we are to prevent them from entering water sources like rivers and oceans. This not only preserves the quality of these water sources, but also protects the fish, birds, and other wildlife that either live in or consume water from these sources. 

Benefits for Health: Microplastics are almost impossible to avoid. Research has determined that microplastics can be found in the human body, including the lungs, blood, breast milk, and placental tissues of expectant mothers. The continual exposure from so many sources can pose a risk to health. While microplastic filtration won’t solve this problem entirely, it does help to eliminate large amounts of microplastics from the water we are exposed to and consume. 

Improved Clean Water Standards: As wastewater treatment plants become more capable and efficient at removing microplastics, we’re able to advocate more strongly for better filtration standards. Water treatment facilities are in a position to be the leaders in advocating for improved benchmarks for water purity. 

Future Innovations and Research in Microplastic Filtration 

Today, it’s more important than ever that we’re looking toward the future for innovations in microplastic filtration. We’re seeing some promising new tools on the horizon. 

An example of this innovation is advanced membrane filters that are capable of filtering microplastic particles more efficiently. Biofiltration, using biological methods to trap and remove minuscule microplastics is another area being explored. There are even some scientists looking at how we can break down and degrade microplastics using electrochemical treatments. 

Technology and tools aside, microplastic pollution is an issue that needs to be addressed on a global scale. Countries around the world are beginning to work together, set stronger regulations, and develop collaborative practices for the research and development of microplastic filtration solutions. 

Solving the Complex Problem of Microplastics with Wastewater Filtration 

There’s no question that microplastic pollution is one of the most challenging and complex problems the wastewater treatment industry faces today. These facilities play an incredibly important role in preventing this problem from getting worse. Microplastic pollution is an issue that needs to be tackled on every level, from the role of the individual to the responsibilities of the manufacturing industry, and beyond. Wastewater treatment is one tool that can make a real impact right now.

The impact of climate change is widespread, affecting areas of life that many people don’t typically give much thought to. One such area is the impact on water treatment systems. Rising global temperatures are creating an environment where storms are becoming more intense, arctic ice mass is melting, and sea levels are increasing. This is a recipe that places more pressure on wastewater treatment facilities. 

Wastewater treatment plants serve the important role of keeping water clean and contributing to a healthier environment. The concern is that these facilities have been built with more stable climate conditions in mind. Hurricanes, floods, and drastic shifts in rainfall levels have been considered outliers, not the norm. The fact that they are becoming more common is a challenge. 

The Effects of Climate Change on Wastewater Treatment Efficiency

Changes in climate have an immediate and direct impact on wastewater treatment plant efficiency. We see these effects in a number of ways. 

Effects on Biological Treatment Processes

Biological treatments are important for breaking down certain types of organic wastewater pollutants. This process involves using microorganisms, like bacteria, that will feed on organic matter, essentially clearing it from the wastewater. 

Temperature changes associated with climate change are creating challenges for biological treatment processes. Higher temperatures can interfere with the efficiency of biological treatment, making it more challenging to remove organic contaminants. As temperatures rise, this also creates an environment where harmful bacteria can thrive, further reducing the water quality that comes through wastewater treatment facilities. 

Overwhelmed Systems

Some areas of the country have experienced devastating rainfall and flooding due to hurricanes and other extreme weather events. This takes a toll on wastewater treatment facilities. During these events, facilities can easily overflow, which overwhelms the systems. When systems become overwhelmed, they are not able to effectively filter and treat wastewater. 

The result is wastewater that is either untreated or only partially treated spilling over into ournatural waterways. The unfortunate consequence of this is increased pollution levels that are bad for the ecosystems they support, and our environment as a whole. 

Reduced Water Availability

In contrast to flooding, other areas have experienced periods of prolonged drought, which also has an effect on the efficiency of the water treatment process. Less water means that pollutants in the water can become more concentrated, creating challenges for filtration and purification. 

Challenges for Coastal Water Treatment Facilities 

A challenge that is specific to wastewater treatment facilities in coastal areas is the amount of saltwater exposure as a result of rising sea levels. This can lead to interference with treatment processes but also cause damaging corrosion of equipment. Combined, these lead to reduced efficiency overall. Looking at the long-term effects, wastewater treatment plants are then faced with the financial challenges of repairing or replacing costly equipment. 

Current Infrastructure Challenges in Wastewater Treatment Due to Climate Change 

As the effects of climate change have crept up on the wastewater treatment industry, the effects of the added stress on the infrastructure are reaching a critical point. One of the most significant areas of concern is the industry’s aging infrastructure. 

The fact that the majority of wastewater treatment plants are decades old at this point, means they were built during a time when the effects of climate change were a less pressing issue.  Older facilities with aging equipment aren’t designed to handle the load of our modern environmental pressures. This means aging equipment needs to be replaced sooner than anticipated, adding extensive costs to already stretched budgets. 

Geographical challenges are also becoming a more prominent issue. Facilities in lower-lying areas are now dealing with flooding that wasn’t an issue a decade or two ago. Not only does flooding halt processing and lead to lower overall efficiency, but it also leads to costly repairs and potentially the costs associated with relocation. 

From a cost standpoint, electricity costs are an issue that is stressing many facility budgets. Combined with the potential of power outages from extreme weather disrupting service, more wastewater treatment centers are at a point of considering alternative energy sources. While more efficient in the long term, this can be a costly venture upfront. 

Exploring the Environmental and Public Health Implications of Inefficient Wastewater Treatment 

When looking at the effects of climate change on wastewater treatment facilities, it’s important to also look at how all of this affects public health and the environment. 

Public Health Risks: One of the most significant implications is the risk to public health. When wastewater treatment systems become overwhelmed or work inefficiently, this opens up the door for the discharge of untreated water. As a result, we see an increase in the presence in not-so-friendly microorganisms, including viruses and bacteria that can spread disease among humans. This can significantly increase the risk of waterborne illnesses in affected communities. 

Increased Water Pollution: As mentioned earlier, the risk of dangerous water pollution is increasing as a result of climate change. Pollutants that include chemicals, pathogens, and nutrients that can be harmful in uncontrolled amounts harm aquatic life and the area’s ecosystems.

Issues with Algal Blooms: The nutrients we just mentioned can create a scenario where higher than-normal levels of nitrogen and phosphorus exist. The result of this is an increase in algal blooms. Large algal blooms on the surface can block sunlight from reaching the life below the surface. This is especially troublesome for plant species that rely on photosynthesis. Algal blooms can also rob the environment of nutrients and deplete oxygen. All of this combined can have a devastating effect on water ecosystems. 

Economic Significance: It’s equally important to consider the long-term economic consequences of the impact of climate change. Everything from wastewater treatment infrastructure that needs to be replaced, to the increased cost of healthcare and the financial stress on fishing and tourism industries has an impact. 

Strategies for Enhancing Wastewater Treatment Resilience to Climate Change 

While the impact of climate change on wastewater treatment facilities is nothing to take lightly, it’s not all gloom and doom either. There are steps that can be taken today for the industry to adapt. 

• It’s Time for an Infrastructure Upgrade: Facilities with outdated infrastructure can stay ahead of the damage by updating their equipment and technology, such as advanced filtration systems and UV disinfection. Updating facilities before it becomes a necessity allows for more financial control and management of the process. 
• Implementing Renewable Energy: Wastewater treatment plants can look toward renewable energy, such as solar power, wind power, or biogas. The less reliant facilities become on external power resources, the more resilient they become against power outages. 
• Flood Proofing: Wastewater treatment facilities in flood areas can take steps to install flood barriers and other flood prevention strategies. 
• Shifting Toward Corrosion-Resistant Materials: Equipment made from corrosion-resistant materials can reduce maintenance and extend the lifespan of treatment centers located in coastal regions. 

Managing the Effects of Climate Change in Today’s World

Climate change is changing how wastewater treatment plants function and posing challenges to their efficiency. Extreme weather is becoming more common, and as environmental shifts continue to occur, wastewater treatment plants are required to adapt. Upgrading infrastructure and investing in durable equipment is a good place to start. 

Wastewater treatment centers carry a huge responsibility. Being equipped with the latest tools and technology can help these facilities succeed, even in the face of climate change.

Water is essential to daily life in so many ways, and we couldn’t live without it. Water treatment facilities are responsible for taking wastewater and treating it to remove contaminants before it makes its way to our soil and natural water resources. To accomplish this, wastewater treatment facilities can use either biological or chemical water treatment methods. 

Both methods are effective, but they work differently and are best used in different scenarios, against specific types of contaminants. Let’s take a closer look at both biological and chemical treatment methods, and how they’re different. 

What Is Biological Water Treatment?

Biological water treatment is a process where microorganisms, such as bacteria, are used to eliminate organic matter in the water. Microorganisms essentially consume and break down organic matter. The organisms used in biological water treatment thrive and are robust in environments such as wastewater that contains organic pollutants. Through microorganism consumption, harmful pollutants are converted into less harmful byproducts. 

There are two different processes used in biological water treatment. The first is aerobic wastewater treatment. With this method, microorganisms that require oxygen are used. Wastewater is transferred to an oxygen-rich environment where microorganisms can get hard to work breaking down contaminants. Wastewater treatment facilities that treat sewage will often use an aerobic process when using biological water treatment. 

The other process is anaerobic treatment, which is the exact opposite of aerobic treatment. In this case, microorganisms that can thrive in environments void of oxygen are used. This process is fermentation, much like how fermented foods, such as pickles or sauerkraut are created in an oxygen-free environment. Anaerobic treatment is effective for certain types of waste, such as the sludge left after wastewater treatment. 

Understanding Chemical Water Treatment

Chemical water treatment relies on chemical reactions to remove pollutants from wastewater. Chemicals are added to wastewater to neutralize the pollutants. Once the chemicals are added, a chemical reaction occurs, resulting in the contaminants separating from the water so that they can be easily removed. Other times, chemicals are added to kill potentially harmful pathogens. Water that has been chlorinated is a common example of this. 

A benefit of chemical water treatment is that it is very fast and effective. In situations where wastewater must be treated quickly, chemical treatment is typically the preferred route. 

How Are They Different

Both biological and chemical treatments are effective for cleaning wastewater. Wastewater treatment facilities need to consider the differences between the methods, rather than the similarities when choosing which process to use. 

The most obvious difference is the nature of the treatment. Biological treatment removes contaminants through a natural process that breaks down organic waste. Chemical treatment relies on the use of chemicals to either kill, neutralize, or remove pollutants from the wastewater. 

From an efficiency standpoint, chemical treatment is much faster. However, biological treatments may be preferred when there isn’t a sense of urgency or reason for the wastewater to be treated quickly. 

Each method has applications that it is best suited for. With biological treatment, it’s most effective at breaking down various types of organic matter. This would include organic materials such as plants, food, and human waste. For this reason, biological treatment is generally preferred for sewage. On the other hand, chemicals are effective at breaking down pollutants that microorganisms aren’t effective against. This includes pathogens and pollutants such as heavy metals. 

There’s also an environmental impact for each type of wastewater treatment. Biological treatments are considered to be more environmentally friendly. When microorganisms are introduced to wastewater treatment environments, the process is a natural one. In contrast, chemical treatment can lead to toxic byproducts, which present their own issues with removal and management. Chemical treatment can be exponentially more effective in certain cases, but it does require more careful thought and handling.

Best Uses for Biological and Chemical Treatment Methods

Using the right wastewater treatment method means a more efficient process and cleaner output. Treatment facilities need to consider the types of pollutants they need to clear from the water, along with other factors in deciding which process to use. 

Chemical wastewater treatment serves an important role. It’s the primary means of disinfecting potable water. With new initiatives supporting the reuse and recycling of wastewater, effective and safe chemical treatments are important. 

For example, chlorination is effective in killing harmful pathogens. The level of chlorine used for disinfecting drinking water isn’t the same as what’s used in swimming pools, which many people are familiar with. The tap water that comes from your faucet has likely been treated with a low level of chlorine to kill organisms you don’t want anywhere near your food, beverages, or skin. 

Treatment facilities that handle medical wastewater, such as from hospitals, face unique treatment challenges. A combination of pharmaceutical residue, chemicals, and pathogens, requires an approach to effectively treat the water so that it’s safe for disposal. In this scenario, chemical treatment is the safest option. 

Chemical wastewater treatment is also used when heavy metals, such as lead, mercury, or arsenic are involved. These metals cannot be degraded using biological methods, so the industry turns to chemical treatment to ensure compliance with wastewater regulations. 

While chemical treatment is highly effective in these cases, it’s not a viable option for all treatment facilities. Municipal wastewater treatment plants often turn to biological treatment which is ideal for organic matter found in domestic wastewater and sewage. By using microorganisms, municipal wastewater becomes safe to release into natural water sources. 

The same is true for agricultural wastewater treatment, which typically contains significant amounts of organic waste. This includes everything from organic plant residue to animal waste. A major benefit of biological treatment in this case is the generation of biogas. 

Biogas is a renewable energy source generated from the breakdown of organic matter, such as that found in agricultural wastewater. Biogas has many potential uses including being transformed into fuel for vehicles. 

Industrial wastewater can be high in contaminants best suited for chemical treatment, but this isn’t always the case. Industrial wastewater from industries like food and beverage produces a high level of organic matter that can be mitigated through biological treatment. 

The dairy industry is a great example of this, as biological treatment can be used to degrade organic waste produced as a result of bovine milk processing. Breweries, both macro and micro also produce wastewater filled with organic pollutants, necessitating the use of biological treatment agents. 

Biological and Chemical Treatment Are Both Important 

Biological and chemical wastewater treatment processes each have pros and cons, but each is important for effective and safe treatment. In the United States, each individual person produces as much as one hundred gallons of wastewater each day. Utilizing both wastewater treatment methods and continually looking toward new, innovative methods, allows the industry to manage wastewater in the most effective way.

We’re seeing changes both big and small with emerging wastewater treatment regulations. From increased pressure to address some of the bigger issues with wastewater treatment to the adoption of innovative technologies in the wastewater treatment industry, each change in regulation is important for maintaining clean, sustainable water resources while continuing to meet global industrial needs.  

Strict Effluent Standards

Effluent standards are put into place to regulate the level of allowable pollutants that can enter the environment through wastewater. Governments are tightening regulations around the thresholds for wastewater pollutants. This includes common contaminants like heavy metals and chemicals, but also others that you might not think of as being dangerous. 

Nutrients, such as phosphorus can be problematic. The same is true for nitrogen. Current regulations are pushing for lower concentrations of phosphorus and nitrogen to be released into the water. The issue here is that excess nutrients overfeed algae and plant life, leading to damaging overgrowth. 

Reuse and Recycling Mandates

Water scarcity is a growing concern. As we begin to look toward solutions, wastewater treatment is emerging as one possible answer. Regulations regarding the reuse and recycling of treated wastewater have the potential to change the course of water scarcity in regard to agriculture and other industries. 

We’re already seeing changing regulations in California to increase wastewater reuse. On a global scale, Singapore has been a leader in putting initiatives in place to recycle wastewater into potable water. 

If the idea of wastewater as potable water sounds unsanitary, rest assured that filtration and disinfection technologies have kept pace and are capable of safely and effectively purifying wastewater. 

Emerging Contaminant Regulations

Today, we’re seeing an increasing focus on wastewater contaminants that have not previously been prioritized. For example, the growing concern over the level of PFAS in wastewater is catching widespread attention. 

As a result, the Environmental Protection Agency has begun regulating PFAS in drinking water. As a natural consequence, wastewater treatment facilities are in a position to both test their wastewater product for levels of PFA and adopt new methods to reduce or eliminate them. 

We can expect to see more changes like this in emerging regulations as more attention is brought to the levels and potential dangers of chemicals in our water supplies. 

Impacts of Regulations on Treatment Technologies

The goal of emerging regulations is to provide overall cleaner wastewater and lessen the burden on the environment, water supplies, and human health. The impacts of these efforts are far reaching and require new technologies to keep up with the increased demands. 

As a result, we’re seeing innovation in wastewater treatment technologies. Membrane bioreactors combine the efficiency of membrane filtration systems with biological treatments to meet the demands of stricter regulations, without increasing the burden on the environment. Innovations in technology that allow for safe, clean, and efficient water recycling is also an exciting area of interest in the wastewater treatment sector. 

Challenges in Meeting New Regulatory Demands

The shifts in regulations to protect our water, health, and environment are important. As the world around us changes, so must our approach to meeting tighter regulations. These regulations are overall positive movements for the future, but this doesn’t mean they don’t come without challenges. 

For example, technological limitations can pose a challenge. The removal of contaminants like PFAS is extremely difficult with current technology. The industry needs solutions that are not only effective, but also affordable enough to be adopted on a large scale.

There are also concerns as to how smaller wastewater treatment facilities, that might be operating with older technology and reduced budgets, will be able to adapt without significant stress on their operations. 

What the Future of Wastewater Treatment Looks Like 

So, what does the future of wastewater treatment look like with all of these emerging regulations and changes in the industry? With new regulations comes a shift toward sustainability and energy-neutral treatment facilities. Green energy technology is coming into focus and new innovations are on the horizon. 

Water reuse is an area we’re expecting to see become a priority in wastewater management strategies. This includes moving toward more closed-loop systems, which are key for water recycling. 

There’s also the potential for artificial intelligence and machine learning to play a more prominent role in improving wastewater treatment processes, making them more efficient and more cost-effective while meeting tighter regulations. 

Final Words

Emerging regulations are shaping the future of wastewater treatment. New regulations are pushing the industry as a whole to look more closely at sustainable practices and developing innovative ways to approach purification. We see emerging regulations as being the force that drives innovation and beneficial changes in wastewater treatment. Contact us today to learn more!
