  • What is poly ferric sulfate (PFS)?
  • Poly ferric sulfate (PFS) with the general formula of [Fe2 (OH) n (SO4)3-n/2] m (n < 2, m > 10) is a relatively new kind of inorganic coagulant. It has been reported by several researchers that it e...
  • What is the difference between PFS and Fe water treatment?
  • The water treated by PFS was much closer to neutral but fluctuated from 7.9 to 7.2 at dosages of 0.05–0.3 mmol L −1 as Fe, which showed similar performance among the three kinds of PFS. However, in the aspects of the requirement for the equipment, production cost and the scope of application, each method has different advantages.
  • Is PFS an effective coagulant for water and wastewater treatment?
  • Overall, while PFS can be an effective coagulant for water and wastewater treatment application, its use should be carefully considered in light of its economic and environmental impacts. More research is needed to synthesise PFS that is promising and acceptable for use in industry.
  • What is the turbidity removal rate of water treated by PFS?
  • When the coagulation dosage was 0.1 mmol L −1 as Fe, the turbidity removal rate was around 84% and the removal rate of natural organic matter (NOM) was 35%–40%. The water treated by PFS was much closer to neutral but fluctuated from 7.9 to 7.2 at dosages of 0.05–0.3 mmol L −1 as Fe, which showed similar performance among the three kinds of PFS.
