Heterotrophic bacteria

Vedclass · Answer

(B) During the secondary treatment of sewage,the primary effluent is passed into large aeration tanks. In these tanks,the effluent is constantly agitated mechanically and air is pumped into it. This allows for the vigorous growth of aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh-like structures). These microbes are heterotrophic in nature,meaning they consume the organic matter present in the sewage,thereby significantly reducing the Biochemical Oxygen Demand $(BOD)$ of the effluent.
