This recirculation is usually a critical element on the activated sludge process. The recycled microbes are well acclimated into the sewage ecosystem and conveniently metabolize the organic and natural resources in the main effluent. The remaining 70 p.c on the secondary sludge has to be treated and disposed of in a suitable manner (
