cationic polyacrylamide copolymers pam water treatment chemicals
cationic polyacrylamide copolymers (pam) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. concern has been expressed since little is known about the degradation of pams in soils.

novel thermodynamic mechanisms of co-conditioning with low cost
co-conditioning with 15 mg g −1 pac and 1 mg g −1 pam demonstrated superior dewatering, reducing co-conditioned sludge’s specific filtration resistance (sfr) to 4.38 × 10 12 m −1 kg −1, only 48.1% of raw sludge’s sfr. the cst after combined flocculation treatment decreased by 51.44%.
research on a new cationic polyacrylamide (cpam) with high purity,compared with cpamd and the commercial flocculants, the sludge dewatering effect (fcmc and srf) of tpamd has been evidently improved by 1.4% for fcmc and 1.01 × 10 12 m/kg for srf at least based on the sludge dewatering and flocculation test. tpamd had good flocculation effect on water plant sludge.
