About 30 per cent of your sludge is recirculated back again into the aeration tank, where it is actually combined with the primary effluent. This recirculation is a critical characteristic of the activated sludge process. The recycled microbes are well acclimated to the sewage environment and conveniently metabolize the organic elements in the principal effluent. The remaining 70 p.c on the secondary sludge should be treated and disposed of in an acceptable way (
