  • What is the difference between polyacrylamide and polyferric sulfate?
  • Polyacrylamide (PAM) is a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile and environmental protection. Polyferric sulfate (PFS) is a polyhydroxy, combination of multi-core, cationic polymeric inorganic flocculant. It can be quickly mixed with water at any ratio
  • 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.
  • Can PFS be used in tertiary treatment of municipal wastewater?
  • Overall, PFS is highly efficient in removing the phosphate ions and, particularly, achieving the limit concentration in wastewater to be discharged in sensitive areas, even with the lower applied dosage, thus illustrating the potential of PFS for efficient employment in the tertiary treatment of municipal wastewater.
  • Is PFS a good coagulant?
  • Furthermore, it has been reported by several researchers that PFS exhibits a superior efficiency in the removal of chemical oxygen demand (COD), biochemical oxygen demand (BOD), turbidity and colour, than the conventional coagulants based on iron , , .
