  • Which oxidizing agent is used in the synthesis of PFS?
  • The synthesis of PFS commences with the oxidation of ferrous sulphate (5.59 × 10 −3 M as Fe) to ferric sulphate in highly acidic conditions (H 2 SO 4, 96 wt%). The oxidising agent was nitric acid (HNO 3, 65 wt%). FeSO4+1/2SO42−+oxidising agent→1/2Fe2(SO4)3(Step 1. Oxidation)
  • 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.
  • How effective is PFS in removing phosphate ions from municipal wastewater?
  • PFS is highly efficient in removing the phosphate ions from biologically pre-treated municipal wastewater. Moreover, PFS samples exhibit a significantly better coagulation performance, than the respective conventional coagulant, i.e. ferric sulphate, in treating such a wastewater under the applied experimental conditions.
