dephosphorization agent dephosphorizer polyferric sulfate polyferric sulphate water treatment chemical

Polyferric sulfate (PFS) is a type of inorganic coagulant that is commonly used in water and wastewater treatment. It is a polymeric compound that is formed by the reaction of ferric sulfate with hydrochloric acid,resulting in a complex mixture of polymeric species with varying degrees of polymerization.
PFS is a highly effective coagulant that can be used to remove suspended solids, organic matter, and other impurities from water and wastewater. It is particularly effective in the removal of colloidal particles and organic compounds that are resistant to other treatment methods. PFS works by destabilizing the colloidal particles, allowing them to aggregate and form larger flocs that can be more easily removed by sedimentation or filtration.
In addition to its coagulation properties, PFS also has some disinfection properties that can help to reduce the bacterial content of the treated water. It is also relatively stable and has a long shelf life, making it a convenient and cost-effective option for water treatment.
