As a new, high-quality and efficient inorganic polymer flocculant of ferric salt, polyferric sulfate is widely used to purify drinking water, industrial circulating water and industrial wastewater from chemical, petroleum, mining, papermaking, printing and dyeing, wine making, steel, gas and other industries.

In the process of use, the liquid polyferric sulfate is usually prepared into 10% - 50% aqueous solution (which can be directly added when the turbidity of source water is high), and the solid polyferric sulfate is prepared into 10% - 30% aqueous solution. Then according to the specific situation, the conditions and dosage of the prepared solution are put into operation, and the good coagulation effect can be achieved by fully stirring.

According to the different turbidity of raw water, the appropriate dosage can be determined. General turbid water (turbidity 100-500mg / L) use this product 30-50kg per thousand tons, can be appropriate to add high turbidity industrial sewage non drinking water.

In the treatment of industrial wastewater, the first grade product polyferric sulfate was diluted to 1 ~ 2 times of water solution. When the concentration of source water is high and the amount of treated water is large, it can be directly added. Then according to the results of indoor simulation test, according to the appropriate process conditions and dosage, full stirring and coagulation sedimentation, the clarified water can be obtained.

The water treatment plant can also be diluted 2-5 times before adding. The dosage can be determined according to the nature of raw water, through production debugging or beaker experiment, depending on the amount of alum formation. The original dose of other drugs can be used as a reference for water treatment plants. Under the same conditions, the amount of the product is approximately equivalent to the amount of solid polyaluminum chloride, which is 1 / 2-1 / 3 of the amount of solid aluminum sulfate. If the original product is a liquid product, it can be calculated according to the corresponding drug concentration, which is roughly determined by the weight ratio of 1:3.
