Polyferric Sulphate

Polymeric Ferric Sulfate (commonly abbreviated as PFS) is a high-efficiency inorganic polymer flocculant with a chemical formula generally expressed as [Fe₂(OHₙ(SO₄)₃₋ₙ/₂)]ₘ. It is a reddish-brown powdery solid or dark brown liquid product, featuring strong hygroscopicity, good solubility in water, and no secondary pollution. As an upgraded alternative to traditional flocculants such as aluminum sulfate and ferric chloride, it has become a core agent in the global water treatment industry due to its excellent performance and environmental friendliness.

COA:

Printing and dyeing wastewater: Efficiently removes water chroma (decolorization rate over 90%), while reducing COD and BOD(Biochemical Oxygen Demand); treated water meets recycling or discharge standards.
Papermaking wastewater: Adsorbs and removes fiber impurities and lignin from wastewater, improves water clarity, and supports the recycling of papermaking wastewater.
Food-grade Polymeric Ferric Sulfate can be used in waterworks and rural safe drinking water projects, replacing traditional aluminum salt flocculants to avoid potential harm of aluminum residues in water to the human body. It also efficiently removes sediment, algae, and colloidal substances from raw water, improving drinking water safety and taste.

Aquaculture: Adjusts the transparency and water quality of aquaculture water, inhibits the reproduction of harmful microorganisms,and creates a good aquaculture environment.
