3、e simultaneous thickening, digestion, and dewatering of waste activated sludge w as investigated. After 19 days of operation, the total reduction in efficacy of the instantaneous sludge thickening and digestion system in term of mixed liquid suspended solids (MLSS) and mixed liquid volatile suspende

4、d solids (MLVSS) was approximated at 63.7% and 80% , respectively, and the MLVSS / MLSS ratio decreased from 80.8% to 67.2%. The MLSS concentratio n reached 39 g / L from an initial on the day of 7 g / L, indicating a good thickening efficacy. In using FO for sludge dewatering, two major factors wer

5、e verified, namely, initial sludge depth and draw solution (DS) concentration. A sludge depth of 3 m, w here a dry sludge content of approximately 35% can be achieved in approximately 60 m in, is recommended for future applications. In addition, the present study proved the feasibility of using seaw

Introduction Large quantities of excess high water content are produced in wastewater treatment plants (WWTPs) everyday. To minim the costs of sludge transportation and handling, reduction in sludge volume and through water separation is the most important that needs to be addressed prior to final disposal. Sludge thickening and dewatering are usually practic
