  • 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.
  • Why are cationic polyelectrolytes used in wastewater treatment?
  • Synthetic cationic polyelectrolytes (CPEs) serve as coagulation and flocculation agents in wastewater treatment due to a synergy of inherent electrostatic interactions and hydrophilic properties. In wastewater treatment, CPEs act as coagulation and flocculation agents to aggregate impurities and enable water purification.
  • Are cationic polyelectrolytes used as coagulants?
  • According to literature, cationic polyelectrolytes have been most widely used as primary coagulants, however non-ionic and anionic polyelectrolytes are mostly used as flocculants (Bratby 2006). Different types of cationic polyelectrolytes are available commercially.
  • 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).
