  • 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 is the polyelectrolyte producers group?
  • The Polyelectrolyte Producers Group (PPG) is the official association representing companies which manufacture polyelectrolytes in Europe. PPG was formed to further pursue common interests in the safety of polyelectrolyte products.
  • What are organic polyelectrolytes?
  • Polyelectrolytes are those polymers which are water soluble and carrying ionic charge. Organic polyelectrolytes were introduced into environment engineering because of its potentials. Polyelectrolytes are used successfully in water and wastewater treatment (Lee et al. 1998).
  • What are the applications of organic polyelectrolytes in potable water production?
  • Introduction The main applications of organic polyelectrolytes in potable water production are in coagulation and flocculation, and in the dewatering of treatment plant sludges. The water production processes are usually followed by sedimentation and filtration, although with only slightly contaminated waters the sedimentation step may be omitted.
