  • Which cationic water soluble polymer is best flocculant for kaolin suspension?
  • Five cationic water-soluble polymers with different molecular weights and charge densities were obtained and then applied as flocculant for kaolin suspension. It was found that the best flocculation properties showed polymer with highest charge density and molecular weight.
  • What are cationic flocculants used for?
  • Cationic flocculants are normally used to flocculate negatively charged particles, and are used in wastewater and sludge treatment, paper production, oily water clarification, textile industry, paint manufacturing, dairy processing, and biotechnology. Compared to nonionic monomers, cationic monomers are less accessible and stable.
  • Can polymer flocculants improve the performance of dewatering units?
  • The great demand for saving water resources for future gen-erations and protecting the environment from pollutants has driven researchers to synthesize efficient polymer flocculants that could increase the performance of dewatering units with minimum cost.
  • Can aluminum and iron based flocculants improve water treatment?
  • Recently, aluminum- and iron-based floc-culants have been widely used in water treatment applications, and it has been shown that they can improve flocculation com-pared to conventional flocculants.[55–58] Leng et al. synthesized composite flocculant of magnesium salt and poly(DADMAC).
