The special effects of polyferric sulfate (PFS)

Polyferric sulfate (PFS) morphological traits are pale yellow amorphous solid powder, easily soluble in water, 10% (by weight) aqueous solution of a reddish brown transparent solution, hygroscopic. PFS is widely used in drinking water, industrial water, industrial wastewater, urban sewage, sludge dewatering purification.

Widely used in drinking water, industrial water recycling and chemical, petroleum, mining, paper, printing and dyeing, brewing, steel, gas and other sectors of industrial waste water purification treatment, different types of water in different regions can achieve the desired results. When used, generally liquid ferric sulfate in 10% - 50% aqueous solution (in the source water turbidity is high direct dosing), SPFS in 10% - 30% aqueous solution, and then Depending on the circumstances with a good solution at the best conditions and dosing investment, after full mixing the best obtained after coagulation effect.

Polyferric sulfate, the sulfuric acid concentration of about 3% was added to ferrous sulfate, sodium nitrite and then iron phosphate ratio of about 3:100, passing air or oxygen oxidation, hydrolysis, polymerization reaction PFS.

Emergency treatment: isolation leakage polluted area, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wear anti-acid. Do not direct contact with leakage. A small leak: Dust to avoid using cleaner shovel collection in a closed container. Large Leak: plastic sheeting, canvas cover. Cleared under the guidance of experts. Handling Precautions: closed operation, local exhaust ventilation. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators, wearing chemical protective safety glasses, wear rubber acid suit, wear rubber gloves acid. Away from flammable and combustible materials. Avoid generating dust. Avoid contact with alkali, alcohol exposure. Particular attention to avoid contact with water. Handling of light when light unloading, packaging and containers to prevent damage. Equipped with spill response equipment. Empty containers may be harmful residues.

Storage: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat. Relative humidity below 75%. Packaging must be sealed, keep away from moisture. Should be easy (to) combustible, alkalis, alcohols, etc. stored separately and avoid mixing reservoir. Should not go far, to avoid deterioration. Storage areas should be equipped with suitable host material spill.

The use of PFS is very wide, so the application area is very large, the different regions to give us a different feeling, PFS, too, would be better.
