By the second sludge dewatering method, the polyquaternary amine and an anionic polyacrylamide are added separately. By the third sludge dewatering method, a quaternized polyacrylamide, having the polyquaternary amine as part of its polymer chain, is produced by copolymerization of acrylamide with monomers of polyquaternary amine quaternization and is added individually to the sludge. By the fourth sludge dewatering method, the quaternized polyacrylamide from method three is added in concert

Performances and mechanisms of sludge dewatering by a
1. Introduction. The treatment of excess biological sludge has been considered as one of the most serious challenges in wastewater treatment plant (WWTP), because its management consumed about 60% of the total operational expense of a WWTP (Guo and Zhou, 2019; Liu et al., 2016).It must be thickened by reducing moisture due to the more and more stringent rules on the final disposal of the

Polyacrylamide in Agriculture and Environmental Land
Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.
