Product Overview

Strong Coagulation for Demanding Effluent

Polyferric sulfate (PFS) forms dense, fast-settling flocs with outstanding removal of COD, phosphorus, sulfides and color. It performs well in low-temperature water and across a wide pH range, and the iron hydroxide flocs it builds also help co-precipitate heavy metals — making it a favorite for printing & dyeing, tannery, food processing and municipal phosphorus removal.

Produced by long-term partner factories in Gongyi, our PFS powder meets GB/T 14591-2016 with Fe content ≥19%. It pairs naturally with PAM in a two-step coagulation-flocculation setup — and as a one-stop supplier we ship PFS and PAM together in one container under one invoice.

FAQ

PFS — Common Questions

PFS or PAC — which coagulant is right for my wastewater?
PAC is the general-purpose, cost-effective default. PFS wins when you need stronger COD and color removal (dyeing, printing, leather), chemical phosphorus removal, or heavy metal co-precipitation. The decisive test is a jar test on your actual water — we provide free samples of both and our technical team will help you compare results and cost per treated ton.
Does PFS color the treated water?
Correctly dosed PFS does not leave residual color in the clarified water — the iron settles out with the flocs. Overdosing or poor pH control can leave a slight yellow tint, which is why we recommend confirming dosage by jar test. Residual iron in treated water is typically well below the limit relevant to your discharge or reuse standard.
Can PFS and PAM ship together in one container?
Yes. Mixing PFS with PAM, PAC or any of our other products in one container is standard for us — one supplier, one invoice, one document set. This typically reduces your per-ton freight cost and simplifies import clearance in Vietnam and Indonesia.
What is the reference price of PFS?
Reference FOB price is US $230–290 per metric ton (Fe ≥19%, basicity 8-16%) — final quote depends on spec, order quantity and market. MOQ is 1 ton. We send a firm quote with COA, packing and freight options to your port within 48 hours.
