Product Introduction

Polyferric sulfate is a new type of iron ion water purifying agent prepared by hydrochloric acid extraction of ferrous sulfate and then oxidation with a strong oxidizing agent. It is non-toxic, harmless, and has a wide range of applications. It has a high removal rate of COD in papermaking wastewater. When the raw water COD is 500mg/L, the original solution dosage of this product is 1.5-2kg/ton of water, which can reduce COD to below 100mg/L.

Product Use

Drinking water purification, papermaking wastewater, oil-containing wastewater from refineries, leather wastewater, industrial wastewater, pharmaceutical wastewater, and other treatments.

Usage Method

The liquid product can be directly dosed. If the on-site water treatment volume is too large or the original dosing pump flow rate is high, it can also be diluted to a 5-10% aqueous solution for dosing.

Dilute the solid with clean water to about a 5% aqueous solution, and dose according to the small-scale test results (generally, when the raw water turbidity is 100-500, the solid agent dosage is 10-20kg/kiloton of water).
