摘要：Composting of sludge is suitable waste management option as it maintains all essential physicochemical parameters, stability parameters and maturity parameters as per standard norms. The present study was carried out to investigate the applicability of the rotary drum composting technique for the stabilization of sludge from a Common Effluent Treatment Plant (CETP). Rotary drum composting was performed in two runs i.e., winter run and summer run. During the whole composting period in the two runs, the continuous monitoring of the physico-chemical parameters like temperature, pH, electrical conductivity, volatile solids, total organic carbon, ash content, NH4 +-N, NO3 - -N and phosphorus was made. All these parameters are in the agreement with recommended standards of the mature compost. It can be concluded that rotary drum composting could produce acceptable quality of compost which can be used further as fertilizer or soil amendment.
