  • 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).
  • Why is polyacrylamide used in sludge dewatering?
  • Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane…
  • Does GH protect polyacrylamide from environmental degradation?
  • The results of these studies suggest that polyacrylamide can degrade to acrylamides by thermal and photolytic effects, that changes in pH do not promote the depolymerization of polyacylamide, and that GH does protect polyacRYlamide and acrieslamide from environmental degradation. ... ...
