Ferrous Sulfate Heptahydrate

Ferrous Sulfate Heptahydrate – Versatile Iron Source for Water Treatment, Agriculture & Industry

We supply high-purity Ferrous Sulfate Heptahydrate (FeSO₄·7H₂O), commonly known as copperas or green vitriol. This hydrated iron salt serves as an effective coagulant, reducing agent, and nutrient source. Consequently, municipalities and industries actively use it for wastewater treatment, soil amendment, and pigment production. Moreover, its solubility and reactivity make it a fundamental chemical for environmental management, agriculture, and various manufacturing processes.

Core Applications for Ferrous Sulfate Heptahydrate in Key Sectors

This versatile compound fulfills critical roles in environmental protection, crop production, and chemical synthesis. Its functions are both remedial and foundational.

First, the water and wastewater treatment industry relies on ferrous sulfate heptahydrate as a primary coagulant and reducing agent. It effectively removes phosphates, controls hydrogen sulfide odors, and reduces hexavalent chromium in industrial effluent. Therefore, treatment plants depend on it for meeting discharge regulations and improving water quality.

Second, the agricultural sector utilizes it as a soil amendment to correct iron chlorosis in crops and as a micronutrient supplement in fertilizers. Furthermore, it is a key raw material for manufacturing iron oxide pigments, serving as a reducing agent in chemical processes, and in animal feed supplementation.
