Product Map:
Name:New Style Water Purifying Agent-Polymeric Ferric SulfateEnglish name:Polymeric Ferric Sulfate （PFS）Molecular formula::[Fe2(OH)n(SO4)（3-n）/2]m,n<2,m>10,m=f(n)
Product Description:
My company produces solid PFS are using the domestic advanced production technology and the leading domestic level centrifugal spray drying equipment production of inorganic polymer flocculants. Because of its multi-core structure, it purified water at the process, both rapidly and the water surface of colloidal particles of negative charge so that from stable, while in the inter-bridge or ion adsorption arising from flocculation. Generated flocs than significant, sedimentation speed, good flocculation effect, compared with other inorganic flocculant with high purification ability.

Performance characteristics of the product:
1. This product only contains minute quantities of heavy metal ions. It is free of water phase transfer of iron ions and is nontoxic, harmless and safe and secure. This product has wide applications in treatment of drinking water, industrial water purifying and industrial waste water.
2. It has such functions as discoloration, deodorization, de-oiling, de-germing and removing the heavy metal ions and radioactive substances in water. Its rate of removal for COD, BOD and chrominance exceeds 90%.
3. This product has a wide scope of application to PH of water bodies with its scope of application of PH values as PH5-11 and the optimal scope as PH6-9.
4. This product is water diffluent and has a high dissolution rate. After dissolution, no slurry will be left, so, it is convenient to use.
Scope of application:
Polymeric ferric sulfate is widely used in industrial waste water in metallurgy, ceramics, coal separation, paper making, printing and dyeing, leather, petrifaction, electric power and coal carbonization etc. as well as purifying treatment of domestic sewage and pre-treatment of drinking water in town.
