Vedclass · Answer

(C) The process of sewage treatment involves several stages:$1$. Primary treatment: This involves physical removal of particles through filtration (sequential filtration) and sedimentation (grit removal).$2$. Secondary treatment (Biological treatment): The primary effluent is passed into large aeration tanks where it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs.$3$. After aerobic treatment,the effluent is passed into a settling tank where the bacterial 'flocs' are allowed to sediment. This sediment is called activated sludge.$4$. $A$ small part of the activated sludge is pumped back into the aeration tank,and the remaining major part is pumped into large tanks called anaerobic sludge digesters,where anaerobic bacteria digest the bacteria and fungi in the sludge.Therefore,the correct sequence is Filtration $	o$ Sedimentation $	o$ Aerobic bacteria $	o$ Anaerobic bacteria.
