  • Does polyacrylamide flocculating sludge emit a strong odor?
  • Volume 234, article number 630, ( 2023 ) The supernatant fluid and sludge produced by traditional polyacrylamide flocculant (PAM) flocculation of municipal sewage emit a strong odor, and the dewatering performance of flocculant flocculating sludge based on acrylamide as the main synthetic raw material remains undesirable.
  • What is polyacrylamide flocculant?
  • The traditional use of polyacrylamide (PAM) flocculant for water treatment has been prevalent. However, its synthesis process heavily relies on petrochemical products, resulting in an increased carbon footprint and emissions from chemical production.
  • Where is Pam used in water treatment & sludge dewatering?
  • PAM used as a flocculant in water treatment or sludge dewatering is disposed in high-solid biogas digestors or landfills. 94 Although PAM is typically considered to be relatively recalcitrant to organic decomposition, 95 it can be degraded during anaerobic digestion.
  • 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.
