  • What is cationic polyacrylamide?
  • Cationic polyacrylamide is a water-soluble polymer that is mainly used for sludge dewatering in municipal wastewater treatment plants. The major physical forms of polyacrylamide include powder, liquid, and emulsion or dispersions. The various end-users of polyacrylamide are water treatment, oil and gas, pulp and paper, mining, and other end-users.
  • Are cationic polyacrylamide copolymers bad for the environment?
  • 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 is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
  • What is polyacrylamide?
  • Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
