What is Polyferric Sulfate?
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.

What is the Main Application Scenarios of Polyferric Sulfate?
- 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.

FAQ
Q: What is Polyferric Sulphate (PFS)?
A: Polyferric Sulphate (PFS) is a high-performance iron-based coagulant widely used in water and wastewater treatment. It is designed to remove suspended solids, turbidity, and pollutants, making water clean, safe, and clear.
Q: How does Polyferric Sulphate work?
A: PFS works through coagulation and flocculation:
1.Neutralizes charged particles in water
2.Forms flocs that capture dirt, organic matter, and impurities
3.Settles particles quickly, improving water clarity
4.Reduces chemical oxygen demand (COD) and turbidity in wastewater
This makes it ideal for municipal water plants, industrial wastewater, and environmental research.
Q: What are the main benefits of Polyferric Sulphate?
A: 1.High Coagulation Efficiency: Works faster and more effectively than traditional coagulants
2.Wide pH Range: Stable performance in varying water conditions
3.Low Sludge Volume: Reduces disposal costs and environmental impact
4.Versatile Applications: Suitable for drinking water, industrial wastewater, and sludge treatment
5.Research-Grade Quality: Ideal for water treatment studies and pilot projects
Q: What industries use Polyferric Sulphate?
A: Municipal water treatment: Drinking water clarification
Industrial wastewater treatment: Textile, paper, chemical, and food industries
Environmental research: Studies on flocculation efficiency and water purification
Sludge reduction projects: Minimize disposal costs and environmental impact
