  • Can polycarbonate & polyacrylic acid be used for flocculation?
  • When employing each polymer specifically, Al Dawery demonstrated that combining a blend of polycarbonate and polyacrylic acid for flocculation results in improved liquid clarity. The combination of flocculants could raise the sludge volume index by 70%, compared to 40% in the case of polycarbonate alone.
  • 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.
  • 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.
