摘要: The effects of the molecular weight (MW) and charge density (CD) cationic polyacrylamide (CPAM) on sludge dewatering moisture evaporation were investigated in this study. Results indicated that conditioning, optimum dosages 10, 6, 4, 4 mg g−1 CPAM with 5 million MW 20% CD, 40% 3 8 60% respectively. dosage was negatively correlated its CD or if above million. In centrifugal sludge, content conditioned gradually decreased extension centrifugation time, economical force 400×g. rates closely related to dewaterability, which turn significantly either positively solid particles >2 mm size measuring 1 2 diameter. During treatment, reduced from 80% by evaporation, 1.35, 1.49, 1.62, 2.24 times faster using than 6 10 Hence, ideal for dewatering.
