Advanced Iron-Based Poly Ferric Sulphate (PFS) | Efficient Coagulation for Water Treatment
Poly Ferric Sulphate | PFS
Poly Ferric Sulphate (PFS) is an iron-based inorganic polymer coagulant engineered for demanding water purification and wastewater treatment applications.
Presented as a free-flowing yellow to light yellow powder, PFS delivers rapid destabilization, strong aggregation, and reliable clarification across a wide range of water qualities.
What Is Poly Ferric Sulphate (PFS)?
Poly Ferric Sulphate (PFS) is a polymerized ferric coagulant produced through controlled hydrolysis and stabilization of iron salts.
As an experienced PFS manufacturer and exporter, we supply PFS products with stable ferric content, uniform polymer structure, and predictable treatment performance.
Once dissolved, PFS forms a clear reddish-brown solution capable of rapid charge neutralization and strong adsorption bridging.
Compared with conventional aluminum-based coagulants, PFS demonstrates superior decolorization, organic matter removal, and heavy metal capture, while eliminating concerns related to aluminum residuals in treated water.
PFS is widely applied in potable water treatment, municipal sewage systems, and complex industrial effluents where treatment stability and robustness are critical.
Core Advantages of Poly Ferric Sulphate
Powerful Destabilization Capability
Quickly neutralizes colloids and suspended particles, enabling fast floc growth.
Outstanding Color & Organic Removal
Highly effective for colored water, oily wastewater, and high-COD effluents.
Aluminum-Free Chemistry
Ideal for applications where aluminum residue must be minimized or avoided.
Efficient Dosage Utilization
Achieves reliable treatment results with optimized chemical consumption.
Adaptable to Complex Water Conditions
Performs consistently across a broad range of raw water qualities.
