Product Description
Ferrous Sulfate Heptahydrate - Water Treatment Coagulant, Iron Supplement & Soil Amendment
Ferrous sulfate, commonly known as copperas or green vitriol, typically exists as the heptahydrate (FeSO₄·7H₂O), appearing as bluish-green crystals. This versatile ferrous salt plays significant roles in water treatment, agriculture, feed additives, chemical synthesis, and environmental protection, leveraging its properties as a reducing agent, coagulant, and source of iron. It is a cost-effective and readily available basic chemical, offering both economic and environmental benefits.
Core Applications
Water Treatment Solutions
- Coagulation and Phosphorus Removal: Acts as an inorganic coagulant, effectively removing suspended solids, colloids, and phosphates through charge neutralization, adsorption bridging, and sweep coagulation
- Reduction and Decolorization: Utilizes reducing properties to treat chromium(VI)-containing wastewater and partially decolorize dyeing wastewater
Agricultural Applications
- Iron Fertilizer: Most common and economical iron source for preventing and treating iron chlorosis in plants, including acid-loving flowers, fruit trees, and field crops
- Soil Amendment: Lowers soil pH in alkaline or calcareous soils, increasing iron availability and improving soil structure
Feed and Food Industries
- Feed-grade mineral additive providing essential iron for livestock and poultry to prevent anemia and promote growth
- Food-grade nutritional fortifier for products like flour and cereal preparations (compliant with standards like GB 29211)
Chemical and Industrial Manufacturing
- Important starting material for manufacturing iron-based products including pigments, polymeric ferric sulfate, and lithium iron phosphate cathode materials
- Fenton's Advanced Oxidation Process: Serves as ferrous ion source for generating hydroxyl radicals to degrade recalcitrant organic wastewater
- Used in wood preservation and conditioning sewage sludge
