Aerobic treatment such as activated
sludge and aerated lagoon applications is by far the greatest application
of 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.
Most 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." Diffused aeration systems are frequently classified into two major categories according to the diffuser's pore/bubble size, i.e. fine-pore diffusers and medium/coarse diffusers. Medium/coarse diffused aeration systems are used in foul-prone applications.
