Vedclass · Answer

(C) During the secondary treatment of sewage,the primary effluent is passed into large aeration tanks. Here,it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs. Flocs are 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 Biological Oxygen Demand $(BOD)$.

What is formed when aerobic bacteria associate with the fungal filaments in sewage water?
