  • Are cationic polyacrylamide copolymers harmful to the environment?
  • Environ Sci Eur. 2018; 30 (1): 16. 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.
  • What are cationic polyacrylamide copolymers?
  • 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).
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (cPAM), a linear water-soluble and high-molecular polymeric compound with cationic charges, can effectively enhance solid-liquid separation through charge neutralization and interparticle bridging and is widely used worldwide ( Campos et al., 2008; Dai et al., 2014).
  • Why are cationic surfactants used in polyacrylamide adsorption?
  • This is due to the addition of cationic surfactants in the suspension, as cationic surfactants can assist the polyacrylamide adsorption of suspended particles in wastewater through electrostatic action, whereby the more negatively charged suspended particles are in wastewater, the more pronounced is this auxiliary flocculation effect [ 36 ].
