  • Which coagulants are used in polymer flocculation?
  • The dual system used for polymer flocculation was poly (ethylene oxide)/phenol formaldehyde (PEO/PFR) and FeCl 3 -PAM hybrid polymer . It is worth noting that making these extensively used organic coagulants/flocculants , is difficult and costly, which has limited their usage in wastewater treatment.
  • 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.
  • What is the combination of coagulation and flocculation?
  • In industrial practice, the combination of coagulation and flocculation (described by the symbol C/F) is used by applying inorganic coagulants (electrolytes) and flocculants (ionic and non-ionic polymers).
  • Is cationic Pam effective in flocculation?
  • The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers. Non-ionic PAM was shown to be ineffective at flocculating tailing particles. The ionicity of the polymer appears to be highly relevant here, based on the results.
