  • Why is polymeric ferric sulfate used in coagulation treatment?
  • To solve the related problems, polymeric ferric sulfate (PFS) has been extensively used in coagulation treatment due to its low price and high flocculation ratio. However, many previous studies found that the concentration of iron ions in effluents cannot be significantly reduced after the PFS treatment ( Li et al. 2017a, 2017b, 2017c ).
  • 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.
