摘要: Anaerobic digested sludge dewatering is very important in management and disposal. In this study, flocculation behaviour of anaerobic were investigated using metal cations (sodium, magnesium, calcium, ferric aluminium salts) chitosan as dual conditioners. The trivalent ions found to be more effective than the monovalent divalent improving dewaterability measured by capillary suction time (CST). Post-addition into pre-coagulated with further enhanced dewaterability. This study suggests that pre-destabilisation coagulation followed addition polymeric flocculant may improve sludge.
