Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal.
  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
  • What is the rate of degradation of polyacrylamide (PAM) by oxidation?
  • Previous studies have shown high rates of PAM degradation by oxidation. concentrations by more than 95%. coagulation. Membrane processes such as RO can provide treated be high. Detailed cost analyses will need to be performed to polyacrylamide.
