  • Why are polymer flocculants used in water treatment applications?
  • ... Polymer flocculants are commonly used in water treatment applications as they enhance floc size and strength . There are different types of polymers with various molecular weights, charge types, and charge densities, which are used as flocculants .
  • What are organic coagulants & flocculants?
  • Organic coagulants and flocculants (known as biocoagulants/bioflocculants) are usually water-soluble polymers (polyelectrolytes) originated from various natural macromolecule compounds, including polyamines, polydiallyldimethyl ammonium chloride, dimethylamine, and polyacrylamides (PAMs) .
  • Which polymeric coagulants are used in CF operations?
  • Polymeric coagulants whose cationic properties are expressed only in acidic medium and considered weak polyelectrolyte are also used. Examples of cationic polyelectrolytes that have been used in CF operations include poly (diallyldimethyl ammonium chloride), epichlorohydrin/dimethylamine polymers, cationic polyacrylamides, etc.
  • Why do we use polymeric coagulants in water treatment?
  • Relative to the use of the inorganic coagulants in water treatment, the use of polymeric coagulants significantly reduced the coagulant dose requirements, the sludge volume, the ionic load cum the residual aluminium concentrations in the treated water and the process economy (i.e. cost savings of up to 25–30%) [33, 47].
