Polyferric sulfate(PFS) is an inorganic polymer coagulant with excellent performance. Its shape is light yellow amorphous powder solid, which is easily soluble in water. The aqueous solution with a mass fraction of 10% is a reddish brown transparent solution with hygroscopicity. It is mainly used for water purification with good effect and good water quality. It does not contain harmful substances such as aluminum, chlorine and heavy metal ions, and does not contain water transfer of iron ions. Non toxic, harmless, safe and reliable. It has significant effects on turbidity removal, decolorization, oil removal, dehydration, sterilization, deodorization, algae removal, COD removal, BOD removal, heavy metal ion removal, etc. It can also be used for the treatment of industrial wastewater such as printing and dyeing wastewater, and is widely used in foundry, papermaking, medicine, tanning and other industries.
Polyferric sulfate is an inorganic iron salt coagulant. The pH value of the product is acidic. The pH value of the 1% concentration of Polyferric sulfate aqueous solution is about 2.3. If the pH value of the produced Polyferric sulfate is higher than 4, the product is easy to hydrolyze and precipitates will appear in water treatment. However, if the pH value of the produced polyferric sulfate is less than 2, the alkalinity of the product is relatively low, and a large amount of alkaline regulator needs to be added during use, which increases the cost of water treatment.
Solid polyferric sulfate products need to be stored in a ventilated, dry and heat-resistant place, and transported waterproof and moisture-proof. During the transportation process, pay attention to prevent heat and moisture and avoid package damage. The product is packaged in 25kg / bag, double-layer packaging with plastic moisture-proof film and woven bag. For the polyferric sulfate products after unpacking, pay attention to seal the packaging bag before use, empty the air in the bag and avoid atomization and hardening of polyferric sulfate.
