  • What is coagulant polymeric aluminum ferric sulfate (PAFs)?
  • In addition, the introduction of the PO 43 − group in the PFS improved the degree of polymerization, and increased the stability of the product . In this study, the composite coagulant polymeric aluminum ferric sulfate (PAFS) was synthesized using FeSO 4 .7H 2 O and nitric acid (HNO 3) under different Al/Fe, OH/Fe and P/Fe molar ratios.
  • Can polymeric aluminum ferric sulfate be used as a modified coagulation reagent?
  • Conclusions In this research, results of an experimental study on polymeric aluminum ferric sulfate as a modified coagulation reagents for treatment of wastewater were presented. During the process of preparing PAFS, parameters influencing the synthesis process were experimentally tested.
  • Can polymeric iron sulphate be used for industrial effluent treatment?
  • The combination of PFS with other chemicals or natural coagulants has high potential in treating water or wastewater. This is due to their greater effectiveness and cheaper cost compared to inorganic coagulants and organic flocculants . Previous studies of composite polymeric iron sulphate for different industrial effluent treatments
  • Why are PFS coagulants better than ferric sulphate?
  • Therefore, as the PFS coagulants consist mainly of polymeric species, they exhibit better coagulation behaviour. It is worth noting that for a 90% removal efficiency, only 20 mg/l of PFS are required, whereas the respective dosage of ferric sulphate in this case is much higher, i.e. 30 mg/l.
