  • 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.
  • 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 .
  • Does waste-activated sludge fermentation improve polyacrylamide biodegradation?
  • J. Water Process Eng. 18, 29–40 (2017). Dai, X. et al. Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal. Sci. Rep. 5, 11675 (2015).
  • Does the copolymer conditioned sludge improve the dewatering performance?
  • This result shows that after the sludge was conditioned by the copolymer, the bound water in the floc gaps was converted into free water, thereby improving the dewatering performance.
