Aerobic treatment such as activated
sludge and aerated lagoon applications is by far the greatest application
of mechanical aeration equipment. Aeration is also used in water
treatment operations for chemical oxidation of inorganic constituents such
as iron, manganese and hydrogen sulfide. It is also used for odor
control and/or oxygen content restoration.
Suspended growth or activated sludge systems typically consist of some type of pretreatment followed by an aeration basin and a final solids separation unit. The purpose of pretreatment is to remove large suspended solids than can interfere with the mechanical features in biological treatment equipment or to reduce the organic load reaching the aeration basin. . Most aerator types and brands are suitable for activated sludge applications, but each has its own best applications. For example, brush aerators are best for oxidation ditches while fixed diffusers and surface aerators are best for conventional AS systems. The key is to size the unit properly for each application. Once OTR characteristics are established, the sizing is fairly straightforward. Other factors include alpha factor, impact of floc size and settleability, impact on effluent TSS, etc. The key phrase is "if properly sized/selected."
