Vedclass · Answer

(C) Sewage treatment involves the use of microorganisms to break down organic matter present in wastewater. Specifically,heterotrophic bacteria are used in the secondary treatment (biological treatment) phase. These bacteria grow rapidly and form flocs (masses of bacteria associated with fungal filaments to form mesh-like structures) which consume the major part of the organic matter in the effluent,thereby reducing the Biological Oxygen Demand $(BOD)$ of the sewage.
