Bengal Solid Particle Type Polyacrylamide for Sludge Dewatering

solid bowl type and disc-stack type. ... Govt. of West Bengal] ... a new intense sludge dewatering technique using conditioner of coagulant and flocculant (polyacrylamide) mixture and the ...

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 …

CATIONIC POLYACRYLAMIDE FOR SLUDGE DEWATERING. Issuing time-25 10:43. Currently, the amount of wastewater treated by wastewater treatment plants in China exceeds 125,000,000 m 3 per day. As a result, approximately 6,000,000 dry tons of sewage sludge is generated each year . This amount increases substantially with the development of ...

Cationic polyacrylamide (CPAM) is a type of polyelectrolyte that has been widely used as a sludge conditioner because of its low dosage requirement, …

Polyacrylamide (PAM) used in sludge dewatering widely exists in high-solid anaerobic digestion. Degradation of polyacrylamide accompanied with accumulation of its toxic monomer is important to disposition of biogas residues. The potential of anaerobic digestion activity in microbial utilization of PAM was investigated in this study.

Cationic polyacrylamide（high degree of ion） used for sludge dewatering: 1.Solid content:89% 2.Degree of ion:5-65%(adjustable) 3.Molecular weight:6-15million 5.Disolving time:60mins.
