  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • 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.
  • How is partially hydrolyzed polyacrylamide wastewater treated?
  • Yongrui, P., et al. Treatment of partially hydrolyzed polyacrylamide wastewater by combined Fenton oxidation and anaerobic biological processes. Chem. Eng. J. 273, 1–6 (2015).
  • Does 125 W light reduce photolytic degradation of Pam?
  • Model studies show significant photolytic degradation of PAM under illumination by a 125 W lamp with a photon flux of 5.4 µmol/s, reducing the MW from 1.6 × 10 5 to 7 × 10 4 Da; no degradation was observed using an 80 W lamp with photon flux of 3.5 µmol/s (365 nm) after 3 h.
