Ferrous Sulfate Monohydrate

 Applications 

1. For Agriculture And Crop Nutrition: Ferrous sulfate heptahydrate (FeSO₄·7H₂O, CAS 7782-63-0) is a widely used iron micronutrient fertilizer that corrects iron chlorosis in crops, turf and ornamentals, supporting healthy green growth and improved soil iron availability.

2. For Water And Wastewater Treatment: As an effective coagulant and precipitating agent, ferrous sulfate heptahydrate helps remove suspended solids, phosphates and impurities from industrial and municipal wastewater, supporting sludge settling and effluent quality.

3. For Animal Feed And Nutrition: Feed-grade ferrous sulfate heptahydrate serves as an iron fortification additive in animal feed, supporting healthy iron levels in livestock and poultry production.

4. For Pigments And Chemical Production: The compound is a key raw material for iron oxide pigments and other iron salts, and acts as a reducing agent in electroplating and chemical processes, giving manufacturers a versatile iron source.

5. Reliable Supply For Global Industry: Supplied in high-purity agricultural, feed, water treatment and industrial grades with consistent quality, ferrous sulfate heptahydrate gives farmers, water plants and chemical manufacturers a dependable iron salt with stable supply, flexible packaging and professional technical support.
