Beware Of Problematic Wastewater Aeration Additives
Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for…

A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O2, and all those hungry little microbes are fat and happy. But what…
As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down…
Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated…
Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial…
The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the…
Conserving energy and saving costs are always on the minds of wastewater professionals. Aeration accounts for more than 50 percent of electrical usage at most treatment plants. Improved aeration efficiency…
As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to…
Aeration is the heart of every activated sludge system, as well as the most energy-intensive process. When designing or modifying a wastewater treatment facility, the aeration system design will have…
Wastewater aeration basins Sequencing Batch Reactors (SBRs) are a variation of the activated sludge process that combine treatment steps into a single basin. Based on a fill-and-draw method, major phases…
