Secondary treatment

Vedclass · Answer

(B) The image shows an aeration tank,which is a key component of the secondary treatment of sewage. In this stage,the primary effluent is passed into large aeration tanks where it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh-like structures). These microbes consume the major part of the organic matter in the effluent,significantly reducing the Biochemical Oxygen Demand $(BOD)$.
