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

The cationic monomers on these microblock segments can be polymerized to form a CPAMD with a new cationic microblock structure. In addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (Wiesbrock et al. 2004; Hoogenboom and Schubert 2007

Acidovorax PSJ13, a novel, efficient polyacrylamide

Given the environmental challenge caused by the wide use of polyacrylamide (PAM), an environmental-friendly treatment method is required. This study demonstrates the role of Acidovorax sp. strain PSJ13 isolated from dewatered sludge in efficiently degrading PAM. To be specific, the strain PSJ13 can degrade 51.67% of PAM in 96 h (2.39 mg/(L h)) at 35 ¡ãC, pH 7.5 and 5% inoculation amount

Smectite-polymer composites from cationic polyacrylamide (PAM S,¦Ó40 Cl) were prepared to investigate the adsorption behavior of the smectite after the intercalation procedure. PAM S,¦Ó40 Cl solutions with two different concentrations ( ¦Ã = 5.18 g/L corresponds to 4.3 mmol/L and ¦Ã = 3 g/L corresponds to 4.3 mmol/L) were used to manufacture smectite-PAM + S,¦Ó40 composites.
