Poly Ferric Sulfate (PFS)
Poly ferric sulphate also called Poly ferric sulfate, Polymeric ferric sulfate, Poly ferric sulphate. Poly ferric sulphate as a kind of high efficient inorganic polymer flocculants was widely applied to water treatment. The functions are obvious to the high turbidity of raw water, paper mills wastewater, electroplating wastewater, paint factory wastewater treatment, etc. Poly ferric sulfate (Poly ferric sulphate) is a polyhydroxy, combination of multi-core, cationic polymeric inorganic flocculant. It can be quickly mixed with water at any ratio.
Poly ferric sulphate solids are yellow or light yellow powders that are easily soluble in water. The liquid is a reddish brown transparent liquid. Excellent water purification effect, good water quality, no harmful substances such as aluminum,chlorine and heavy metal ions, no transfer of iron ion water, non-toxic, safe and reliable, turbidity removal, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, removal of COD, BOD, and heavy metal ions in water have significant effects.Poly ferric sulphate provides a large number of macromolecular complexes and hydrophobic hydroxide polymers, which has good adsorption. However, many kinds of nuclear hydroxyl complexes of Poly ferric sulphate in solution are different from organic polymer flocculants, and the relative molecular weight of these polymers is far less than that of organic flocculants. Because of the size and structure of the molecules, these complex ions have strong adsorption and neutralization effect in coagulation. Therefore, the main contribution of the high valence macromolecular complex ions in Poly ferric sulphate solution in coagulation is adsorption and neutralization of the charge of colloidal particles and agglomeration between particles.
Poly ferric sulphate floccules have large surface area, high surface energy, compact structure and certain strength. In the process of sedimentation, Poly ferric sulphate floccules have large adsorption capacity for colloidal particles. Poly ferric sulphate floccules have the function of adsorption coprecipitation and are easy to occur the phenomenon of sweeping deposition. The volume of sediment is small and the sedimentation speed is fast, which greatly improves the coagulation effect of Poly ferric sulphate.
Application And After-Sales Service:
Poly ferric sulfate is widely used in the purification of drinking water, industrail water, industrial wastewater, printing and dyeing wastewater, and municipal wastewater, casting, paper making, medicine, leather making and so on.
