This recirculation is often a vital feature in the activated sludge process. The recycled microbes are very well acclimated for the sewage natural environment and conveniently metabolize the natural elements in the key effluent. The remaining 70 per cent in the secondary sludge have to be taken care of and disposed of in a suitable method (
