The using method of polyferric sulfate (PFS)

Polyferric sulfate (PFS) is widely used in drinking water, industrial water recycling and chemical, petroleum, mining, paper, printing and dyeing, brewing, steel, gas and other industries industrial waste water purification treatment of different types of water in different regions can achieve the desired results .

When used, generally liquid polyferric 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.

Dosage can be different according to the raw water muddy degrees, measured optimal dosage is generally turbid (turbidity at 100-500mg / L) of water, the FDA 30-50 per thousand kilograms of non-potable water may be appropriate industrial wastewater with high turbidity dosage.

Industrial wastewater treatment, it will be first-class products PFS aqueous solution was diluted to 1-2 times. Higher concentrations in the source water, treated water is large, can be added directly. Then based on the results of laboratory simulation test at optimum conditions and dosing dosing, after adequate mixing, coagulation, it can be clarified effluent.

Diluted 2-5 fold purification plant also after dosing. Dosage determined, according to the nature of the raw water through the production debugging or beaker experiment, as the formation of an appropriate amount of alum may be, the original system can be used for other water dosage as a reference, under the same conditions of the product and the amount of solid PAC roughly the same amount of aluminum sulfate is a solid 1/2-1/3. If the original using a liquid product, according to the discretion of the appropriate drug concentration calculations.
