Ferric sulfate hydrate

Ferric sulfate hydrate (CAS 15244-10-7), also known as Iron(III) sulfate hydrate, is an iron-based inorganic salt used industrially as a coagulant, flocculant, and pH-regulating agent.

Where is Ferric sulfate hydrate used?

• Municipal and industrial water treatment: primary coagulant
• Effluent streams: removes suspended solids, phosphates, and turbidity
• Mineral processing: leaching agent and oxidant in hydrometallurgical circuits for metal recovery
• Sulfide ores: recovers copper and other base metals
• Pulp and paper: precipitates lignin and color bodies from effluent before discharge
• Wastewater systems: supports pH adjustment and sludge conditioning where iron-based chemistry is preferred over aluminum alternatives

Good to know: Purity levels and hydration state should be confirmed with the supplier, as iron content and soluble fraction directly affect dosing calculations. Proper storage is required to maintain the integrity of the hydrate.
