Description
Ferrous Sulphate is a widely used iron salt, available in monohydrate and heptahydrate forms. It is used across various industries for its coagulating, reducing, and iron-supplying properties. In water and wastewater treatment, it acts as a coagulant and flocculant for phosphorus removal and odor control. Additionally, it is employed in agriculture as a micronutrient fertilizer, in pigment production, cement additives, and iron fortification in food and feed industries. Ferrous Sulphate is also an effective reducing agent for chromate and other oxidized contaminants.
