This recirculation is a essential element on the activated sludge process. The recycled microbes are well acclimated to the sewage environment and readily metabolize the natural and organic products in the first effluent. The remaining 70 per cent from the secondary sludge needs to be treated and disposed of in a suitable fashion (
