  • Are cationic polyacrylamide copolymers used for sludge dewatering?
  • Environmental Sciences Europe 30, Article number: 16 (2018) Cite this article Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land.
  • Can polyacrylamide improve sludge dewatering performance?
  • Accordingly, chemical methods to enhance sludge dewatering have attracted increasing attention. Polyacrylamide (PAM) is widely used as an organic polymer flocculant to improve the rheological properties of sludge and enhance its dewatering performance.
  • Are cationic polyacrylamide copolymers bad for the environment?
  • Cationic polyacrylamide copolymers (PAMs) 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.
  • Is polyacrylamide a water soluble polymer?
  • Polyacrylamide, a water-soluble polymer formed by the polymerization of acrylamide monomers, is among the most used chemicals for wastewater treatment and sludge dewatering .
