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 boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.
With the evolution of the use of dissolved air and membrane solids separation systems, in many cases treatment capacity at industrial wastewater plants can be increased without adding tank volume. Aeration basins are the heart of a wastewater plant, where the biological removal of pollutants occurs. Aeration provides oxygen to the microorganisms that remove targeted pollutants from the water as well as provides the mixing required for the biological process to succeed.
