Ferric sulfate is an inorganic iron salt with the chemical formula Fe2(SO4)3. It is commonly supplied as a reddish-brown aqueous solution or as solid granules, depending on the application and handling requirements. In water treatment, ferric sulfate reacts in water to form iron hydroxide species that capture and aggregate suspended particles and other impurities, allowing them to be separated through subsequent clarification and filtration. It is particularly useful where treatment systems require a coagulant that can operate across a relatively broad pH range.

Ferric sulfate is used mainly in drinking-water and wastewater treatment, while specialized grades may serve other industrial applications. Product concentration, iron content, acidity, impurities, and physical form are important quality parameters when selecting the chemical for treatment operations. The production process involves iron-containing raw-material preparation, acid reaction, oxidation, concentration, filtration, clarification, quality control, and liquid or solid product finishing.

Plant Capacity and Production Scale:

The proposed ferric sulfate production facility is designed with an annual production capacity ranging between 10,000-40,000 MT, enabling economies of scale while maintaining operational flexibility.
