Cationic polyacrylamide copolymers (PAMs): environmental half

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).

Isolation and Characterization of Polyacrylamide-Degrading

Conclusions. In this work, A PAM-degrading bacterial strain P. putida HI47 was isolated from dewatered sludge. The bacterial isolates grew well on medium with PAM as the sole source of nutrients at pH 7.2¨C7.6 and 36 ¡ãC¨C42 ¡ãC. The presence of glucose improved bacterial growth and the rate of degradation.

Biodegradation of Polyacrylamide and Its Derivatives

Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 ¡Á 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
