The Climb To The Top
Back in the late 1980's when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both…
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…
Making The Best of A Bad O2 Situation
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…
Location, Location – The Key To Aeration
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…
A Lid For Every Pot: Retrofitting To Meet Aeration Challenges
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…
Aeration Considerations: What To Know Before You Buy
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…
Translating Aeration Efficiency Into Dollars
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…
Energy Savings With Jet Aeration: The Devil Is In The Details
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…
How To Boost Industrial Plant Capacity By Retrofitting Aeration Tanks
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…
