product description
Polyferric sulfate is a high-quality, high-efficiency inorganic polymer flocculant. It exists as a light yellow amorphous powder or liquid and is readily soluble in water. It features low dosage requirements, rapid floc formation, fast settling rates, and good sludge dewatering performance. In water treatment processes, it effectively removes suspended solids, organic matter, heavy metals, and phosphorus from water, with a wide pH application range. The residual iron content in treated water is low, and there is no secondary pollution from aluminum ions. It is widely used for the purification of drinking water, industrial wastewater, and municipal sewage.

Product Usage

Polyferric sulfate is a highly effective inorganic polymer flocculant widely used in water treatment. In drinking water and industrial wastewater treatment, it quickly neutralizes the negative charges on the surface of colloidal particles and forms large, dense flocs through adsorption bridging, efficiently removing suspended solids, organic matter, heavy metal ions, and phosphorus. It is particularly suitable for treating low-temperature and low-turbidity water, printing and dyeing wastewater, oily wastewater, and municipal sewage. Compared to traditional aluminum salts, it offers advantages such as lower dosage requirements, faster flocculation rates, lower sludge production, a wide pH application range (4–11), and no aluminum ion residue. Additionally, it is highly effective in sludge dewatering and decolorization of dyeing wastewater.
