Aeration within Water Treatment
Aeration is a secondry treatment process which can be used in municipal or industrial wastewater treatment.
Aeration in an activated sludge process is based on pumping air into a tank, which assists the microbial growth in the wastewater. The microbes feed on the organic material, forming flocs which can easily settle out. After settling in a separate settling tank, bacteria forming the activated sludge flocs are continually recirculated back to the aeration basin to increase the rate of decomposition.
A well designed aeration system has a direct impact on the level of wastewater treatment it achieves.
