Effects of Cationic Polyacrylamide Characteristics on
May 30, 2014· 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

Effective sludge dewatering technique using the
In this study, the combination of Fenton's reagent and cationic polyacrylamide (CPAM) was used in sludge conditioning for the enhancement of sludge dewatering performance. The effects of CPAM, H 2 O 2 , and Fe 2+ dosages and pH on the moisture content (MC) of the filter cake, the specific resistance of filtration (SRF), and the residual

Effects of Cationic Polyacrylamide Characteristics on
Centrifugal sludge dewatering efficiency after CPAM conditioning . In this study, two series experiments were conducted. In the first experiment, the original sludge was conditioned using CPAM with 5 million MW and 60% CD at concentrations of 1, 2, 3, and 4 mg g −1.The conditioned sludge was then dewatered in a centrifuge (TDL-40B, Shanghai Precision Instrument Co., Ltd.) at 1600×g for 300 s.
