Vedclass · Answer

(B) In the secondary treatment of sewage,activated sludge flocs consist of masses of bacteria associated with fungal filaments to form a mesh-like structure.These flocs require a constant supply of oxygen for the aerobic decomposition of organic matter.If the oxygen availability is reduced,the oxygen cannot diffuse into the interior of the flocs.Consequently,the centre of the flocs becomes anoxic (lacking oxygen).This leads to the death of the aerobic bacteria residing in the centre,which eventually causes the structural integrity of the flocs to fail,leading to their breakage.
