Ferrous Sulfate
Product Description
Monohydrate & Heptahydrate | Industrial Grade & Agricultural Use
📌 Product Overview & Key Advantages
Ferrous sulfate is a green or bluish-green crystalline material commonly used in water treatment, fertilizers, and pigment manufacturing. It exists in two common forms: monohydrate (FeSO₄·H₂O) and heptahydrate (FeSO₄·7H₂O), both offering cost-effective iron supplementation and strong flocculating properties.
✅ Two forms available: Monohydrate & Heptahydrate
✅ High iron content, up to 30% Fe
✅ Widely used in wastewater treatment & agriculture
✅ Bulk supply with reliable delivery capacity
✅ Supports OEM packaging & long-term supply contracts
