Cationic polyacrylamide copolymers (PAMs): environmental half life

Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

Research on a new cationic polyacrylamide (CPAM) with a cationic

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.

Preparation, Characterization, and Sludge Conditioning of Cationic

Cationic polyacrylamide (CPAM) has been widely used for sludge conditioning because it can neutralize the surface charge of solid and bridge particles through its long polymer chain to form large flocs that can reduce the specific resistance and cake compressibility of sludge [4,5,6].

Cationic polyacrylamide: synthesis and application in sludge dewatering

The HbQF treatment could not reduce the sludge water content when combined with membrane-based filtration post-treatment because of the pore blocking of fractured and lysed cells; however, it could achieve sludge microbial cell rupture, disinfection, and floc disintegration, causing enhanced reduction of water content and enhanced dewatering capability via a sedimentation post process.

Preparation of a hydrophobically associated cationic polyacrylamide

This effect occurs because the large number of cationic groups in the copolymer neutralize the negative charge of the sludge, and they carry a large number of hydrophobic groups, such as -CH-, -CH 2 - and -CH 3, that form molecular chains that sweep and shrink the sludge flocs, squeezing out the bound water in the sludge flocs and eventually leading to the release of the water and its
