CAS 10028-22-5 polyferric sulfate yellow powder for water treatment

Product description

PFS is the short name of polyferric sulfate. Polyferric sulfate is widely used for source water purification. Such as dyeing, paper making, coal washing, food, leather and other wastewater and municipal sewage treatment.
Especially for the treatment of high turbidity raw water, alkaline printing and dyeing wastewater, polyferric sulfate is better than other flocculants, it not only has obvious turbidity removal effect, but also has good decolorization.

Advantage

1. Fast hydrolysis
2. Soluble in water
3. Wide applicability
4. Less dosage
5. Cost save 20% than other flocculant


Usage and Dosage


1. Dissolve polyferric sulfate into a solution of 10-30% and dilute with water to the desired concentration.
2. The optimal PH value is 3.5-5.0, and the optimal PH value of coagulation can bring into play the maximum benefit.
3. Generally, 0.5-2.0kg (5-20ppm) of polyferric sulfate is added for every 100 tons of turbidity water. When the turbidity of raw water is high, the amount of drug is appropriately increased; when the turbidity is low, the amount of drug can be appropriately reduced.
