Overview
Given the growing population, rising costs, and the introduction of increasingly stringent environmental regulations, what are the key issues that operators of wastewater treatment plant installations face today?
We look at four primary categories, highlighting the most important challenges and examining how technological advancements can assist enhance performance.
People and their habitats all throughout the world rely on clean water to survive. Those who supply excellent wastewater treatment solutions play a critical role in restoring clean, safe water to its source. In treatment facilities, operational efficiency is always paramount, and this has fueled innovation for a long time. Although significant progress has been achieved in the development of efficient technologies in recent years, there are still obstacles to overcome.
What Are Wastewater Treatment Plants’ Biggest Issues?
Here are some of the most pressing issues in wastewater treatment:
Energy Consumption:
One of the most expensive aspects of running a wastewater treatment facility is energy consumption. Wastewater treatment is projected to use 2% to 3% of a developed country’s electrical power, or about 60 TWh (terawatt hours) each year. Biological treatment consumes the most energy in municipal wastewater treatment, accounting for roughly 50 to 60 percent of plant utilization.
Changes in biological treatment processes have the ability to reduce a treatment plant’s energy requirement dramatically. Fine screens in primary treatment, membrane technology for aeration, and direct treatment of high concentration return streams are only a few examples of solutions. We’re working on producing wastewater treatment solutions that are both cleaner and more environmentally friendly. We can lower the amount of energy consumed to treat wastewater. We can do this by combining these greener technologies while preserving the current water treatment infrastructure.
Staff:
Operators of wastewater treatment plants must have the necessary training and certification. They are available 24 hours a day and are in charge of everything from pipe leaks to valves to electrical and instrumentation equipment. During variations in influent and seasons, this labour becomes much more arduous. Wastewater treatment plants, like many other businesses, are suffering from a labour shortage. To successfully treat wastewater, you’ll need efficient and productive personnel that are also skilled in the field. However, there isn’t enough staff to go around.
While the actual presence of people responsible for overseeing activities at treatment facilities will always be required, operator management can account for up to 30% of a wastewater treatment plant’s operational expenditures. Emerging technologies, motivated by a desire to decrease OPEX, make use of the advantages of automation. This can reduce the need for operator involvement. Automation could be a solution to the labour problem. It will not only fill in the gaps in essential jobs, but it will also relieve stress on current employees.
Sludge production:
Sludge is the byproduct of physical, chemical, and biological processing. The disposal of surplus sludge created during the wastewater treatment process is a serious environmental concern. Sludge is the name for the residue that remains after the chemical, physical, and biological treatment procedures have been completed. One of the most difficult problems facing wastewater treatment companies is dealing with sludge and disposing of it in an acceptable, environmentally beneficial, and legal manner. Every wastewater treatment plant must devise long-term, safe disposal strategies for any sludge generated during the treatment process.
A sustainable running facility requires safe and long-term solutions for sludge disposal produced by wastewater treatment plants. The greatest solution is to recycle sludge in agriculture, which contains useful organic matter and nutrients. Some more advanced treatment technologies can even minimize sludge formation, hence reducing the burden. Recycling nutrient- or organic-rich sewage into agricultural fertilizers or soil treatments is now one of the most effective methods. Even more recent developments can aid in reducing the quantity of sludge produced in the first place. This make treatment plants more efficient, cost-effective, and ecologically benign.
Footprint:
One of the most significant issues of activated sludge treatment is the size of the footprint it necessitates. Activated sludge facilities are expensive to build and take up a lot of space. For vast and expensive settling tanks and aeration basins, primary and secondary processes require massive swaths of land. Municipal wastewater treatment plants must improve their capacity as well due to population growth. Treating wastewater is used to filter water in order to make it more environmentally friendly. When wastewater treatment plants treat water, they leave an environmental impact as well. After all, the organic debris that has been removed from the water must be disposed of.
Advanced technologies are leading the way in decreasing footprint. It’s done by increasing the amount of biomass per unit volume by adding media for biofilm attachment (such as IFAS and MABR) or raising the biomass concentration (such as MBR). A smaller footprint means lower land costs, but it also means lower CAPEX (less concrete, steel, and equipment). Green revolutionary technology has improved how we handle water, resulting in a smaller and less impactful environmental footprint from wastewater treatment plants. As automation and innovation improve, we will be able to expand on these environmentally favourable solutions, making wastewater treatment more environmentally friendly.
