effects of cationic polyacrylamide characteristics on sewage sludge

Effects of Cationic Polyacrylamide Characteristics on Sewage Sludge

The effects of the molecular weight (MW) and charge density (CD) of cationic polyacrylamide (CPAM) on sludge dewatering and moisture evaporation were investigated in this study. Results indicated that in sludge conditioning, the optimum dosages were 10, 6, 6, 4, and 4 mg g?1 CPAM with 5 million MW and 20% CD, 5 million MW and 40% CD, 3 million MW and 40% CD, 8 million MW and 40% CD, and 5

enhanced dewatering of waste sludge with polyacrylamide/montmorillonite

Enhanced Dewatering of Waste Sludge With Polyacrylamide/Montmorillonite

In order to improve the waste sludge dewaterability of polyacrylamide (PAM), the composite conditioner of PAM/montmorillonite (MMT) was prepared. The structure and intermolecular hydrogen bonding of the composite were studied, and the effects of PAM/MMT weight ratio and dosage on the dewaterability of the waste sludge were systematically investigated.
