  • 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.
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
  • What is Pam used for in water treatment?
  • PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.
  • How effective is Pam in coagulation?
  • As mentioned above, the coagulation process relied on the adsorption and bridging effect of added PAM forming large flocs to remove PE. From the Fig. 5 a, the removal efficiency of PE was poor greatly when the dosage of PAM was 1 mg/L and 2 mg/L, which was 28.94% ± 0.62% and 36.81% ± 0.61%, respectively.
