  • Which polyelectrolyte is used in water treatment?
  • Synthetic polyelectrolyte namely non-ionic PAM has also been used in water treatment (Selvapathy and Reddy 1992). It consists of 1–3% anionic group as in case of PAM, where they are prepared by hydrolysis of amide groups under controlled conditions.
  • What are polymeric polyelectrolytes?
  • There are many definitions for polymeric polyelectrolytes in the literature , , . In the simplest sense, water-soluble polyelectrolytes are polymers that contain charged disassociating monomer subunits. The charges can be pendant to the polymer chain or be part of the polymer chain itself.
  • Can polyelectrolytes be used with inorganic coagulants?
  • So, organic polyelectrolytes were introduced in conjunction with inorganic coagulants for the treatment of water and wastewater. The optimum dosage of polyelectrolytes in all kinds of water and industrial wastewater can be very low if it will be used in conjunction with inorganic coagulants.
  • 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.
