Solution
The correct option is A primary sludge
Physical removal of particles by filtration and sedimentation. Then the grit is removed by sedimentation. All solids that settle form the primary sludge and the supernatant forms the effluent. The primary effluent is passed into large aeration tanks where it is constantly agitated mechanically and the air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh-like structures).So the correct option is "flocs".
