Product Introduction
Polymeric ferric sulfate( PFS) is a new type of high efficient inorganic polymer flocculants, its chemical general formula is [Fe2(OH)n(SO4)3-n/2]m. The solid is light yellow amorphous powder, liquid is red brown viscous transparent liquid. The solid product has strong hygroscopicity. The condensation performance of this product is good. Stable chemical property, fast settlement, apply to the range of pH is wide, can be widely used in the purification treatment of drinking water, all kinds of industrial water, industrial wastewater and city sewage.
Product characteristics
Compared with other inorganic flocculants, the polymeric ferric sulfate has the following features.
1. New type, high quality, high efficient ferric salts of inorganic polymer flocculant.
2. Coagulation performance is good, can be miscible with water in any proportion, alum flowers dense, high adsorption activity, fast deposition speed, good filterability.
3. Water purification effect is good, the water quality of yielding water is good, does not contain harmful materials such as aluminum, chlorine and heavy metal ions etc. also no iron ion water phase transfer, non-toxic, harmless, safe and reliable.
4. Has the significant multiple benefits, such as decolorization, deodorization, dewatering, oil removing, sterilization and removal of heavy metal ions in water etc. Can effectively remove compounds contain nitrogen, silicon sol, radioactive substances and carcinogens, the removal rate of COD, BOD and colority as high as 90% above.
5. Adapt to the wide range of pH of water, it is from 4 to 11, optimum pH range for 6-9, the variation range of raw water pH and total alkalinity is small after purification, and can effectively remove calcium ions and magnesium ions, reduce the water hardness.
6. The purification treatment effect is remarkable for the raw water of micro pollution, including algae, low temperature, and low turbidity.
7. Less dosage, convenient operation, low cost, processing cost can save 10%-20%.
8. Product storage and treatment effect is stable, not affected by the temperature changes, suitable for area with different climate.
9. Stable performance, still can be stored for a long time after dissolution, without precipitation, not go bad, not plug pipeline.
10. Other series ancillary products: polyacrylamide, ferrous sulfate, poly aluminum ferric chloride, basic aluminum chloride, sterilization algicide, scale inhibitor, anthracite filter media, quartz sand filter material, pebble filter material, manganese sand filter material, magnetite filter material, nut shell filter material, activated carbon and active oxide ball etc.
