  • 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 polyferric sulphate?
  • Polyferric sulphate: preparation, characterisation and application in coagulation experiments. A new inorganic-organic composite coagulant, consisting of polyferric sulphate (PFS) and polyacrylamide (PAA). 2009 3rd International Conference on…
  • How is polyferric sulphate (PFS) prepared?
  • A range of effective optimal formulations of polyferric sulphate (PFS) can be prepared by a novel procedure, recently developed by the authors, involving an oxidation stage followed by a partial…
  • 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.
