  • 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
  • Can ferrous sulfate be used for environmental remediation?
  • The main application of ferrous sulfate for environmental remediation is related ot water and wastewater treatment when FeSO 4 (as a coagulant) could be used as solid waste or after pretreatment methods.
  • Is ferrous sulfate a coagulant?
  • Ferrous sulfate is often used in as a coagulant in wastewater applications as it is cheaper than ferric chloride. However, as was shown in Eq. (4), once dosed it undergoes a two-step reaction to form the iron hydroxide needed to react with inorganic constituents.
  • 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.
