A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Ferric sulfate (CAS 10028-22-5, Fe2(SO4)3) is an iron-based coagulant used in drinking-water and wastewater treatment for turbidity and color removal, phosphorus precipitation, hydrogen-sulfide/odor control, and sludge conditioning. It works across a wide pH range and leaves an iron rather than aluminum residual.
Ferric Sulfate: Applications & Grades
Ferric sulfate coagulates suspended solids and natural organic matter, precipitates phosphate in municipal and industrial wastewater, and controls H2S and struvite. It is often chosen over alum where an aluminum-free residual, better cold-water performance, or odor control is needed. Potable grades meet NSF/ANSI 60 and AWWA B406.

Frequently Asked Questions
What is ferric sulfate used for?
Ferric sulfate is an iron(III) coagulant for drinking-water and wastewater treatment — turbidity/color removal, phosphorus precipitation, hydrogen-sulfide and odor control, and sludge conditioning. It performs across a wide pH range. RawSource supplies NSF/ANSI 60 grades to spec.
Ferric sulfate vs ferric chloride — which should I use?
Both are iron(III) coagulants. Ferric chloride is a stronger acid and adds chloride; ferric sulfate adds sulfate, is often gentler on pH, and avoids chloride where corrosion or chloride limits matter. The best choice depends on alkalinity, target (turbidity vs phosphorus vs H2S), and downstream limits. RawSource quotes both.
Is ferric sulfate NSF certified for potable water?
Drinking-water-grade ferric sulfate is certified to NSF/ANSI 60 and meets AWWA B406. Reference your spec on the RFQ; we confirm certification and provide the CoA.
How is ferric sulfate supplied in bulk?
RawSource supplies ferric sulfate as ~50–60% liquid in bulk and totes, or dry granular in supersacks, under CAS 10028-22-5 / HS 2833.29. Grade, Fe content, packaging, and MOQ confirmed at quotation. Submit a bulk RFQ.
