Effect of Chitosan/Polymeric Aluminum Composite Flocculant on Activated Sludge

Abstract:

Effect of the dosage of flocculants on activated sludge dewatering is analyzed through the determination of sludge specific resistance to filtration．Sludge dewatering behaviors conditioned on PAC, CTS and composite flocculants have been compared. The results show all the conditioning agent have help to sludge dewatering .Compared with Polymeric aluminum , Chitosan(CTS) and PAC/CTS composite coagulant, the optimum coagulant with its optimum dosage is obtained .PAC/CTS can greatly reduce the sludge specific resistance and improves the sludge dewatering performance largely while the clarity of the filtrate was higher.
