Ferrous Sulfate Heptahydrate Supplier in Turkey – Industrial & Agriculture Grade

Ferrous Sulfate Heptahydrate (FeSO₄·7H₂O), also known as Iron Sulfate 7H2O or Green Vitriol, is a water-soluble iron compound widely used in agriculture, wastewater treatment, animal feed, and industrial manufacturing. As a reliable Ferrous Sulfate supplier in Turkey, we provide bulk quantities in 25kg bags and jumbo bags with full export documentation, competitive FOB pricing, and fast container loading.

This crystalline green compound is one of the most cost-effective iron sources for correcting iron deficiency in plants, removing phosphates in water treatment systems, and supporting industrial chemical production.

What is Ferrous Sulfate Heptahydrate?

Ferrous Sulfate Heptahydrate is an iron (II) salt of sulfuric acid containing seven molecules of crystallization water. Its chemical formula is FeSO₄·7H₂O. It appears as pale green to bluish-green crystals and is highly soluble in water.

Because it contains approximately 19–20% elemental iron (Fe), it is commonly used as an iron fertilizer and micronutrient source in alkaline soils.

Key properties:

• Chemical Formula: FeSO₄·7H₂O
• Iron (Fe) Content: ~19–20%
• Appearance: Green crystalline solid
• Solubility: High in water
• pH (5% solution): Slightly acidic

Production Process of Ferrous Sulfate

Industrial production of Ferrous Sulfate Heptahydrate is primarily linked to the steel industry.

During steel pickling, iron reacts with sulfuric acid:

Fe + H₂SO₄ → FeSO₄ + H₂

The resulting ferrous sulfate solution is filtered, purified, and cooled to induce crystallization. Under controlled temperature conditions, green FeSO₄·7H₂O crystals form. These crystals are then centrifuged, dried, and packed.

Since Ferrous Sulfate is often a by-product of steel processing, global supply is closely linked to steel production levels.

Applications of Ferrous Sulfate Heptahydrate

1. Agriculture Fertilizer & Iron Deficiency Treatment

Ferrous Sulfate fertilizer is widely used to correct chlorosis (iron deficiency) in plants. In alkaline soils, iron becomes unavailable to plants. Applying Ferrous Sulfate improves iron uptake and restores green leaf color.

Common agricultural uses:

• Citrus trees
• Olive trees
• Vineyards
• Lawns and turf
• Vegetable crops

It is one of the most economical iron fertilizers available for large-scale farming.

2. Water & Wastewater Treatment

Ferrous Sulfate is used as a coagulant in wastewater treatment plants. It helps in:

• Phosphate removal
• Reduction of odor
• Sludge conditioning
• Heavy metal precipitation

In water treatment systems, ferrous ions oxidize to ferric ions, forming flocs that capture impurities and improve water clarity.

3. Animal Feed Additive

In controlled dosages, Ferrous Sulfate is used as an iron supplement in animal nutrition to prevent anemia and support healthy growth.

4. Industrial Applications

Industrial-grade Ferrous Sulfate is used in:

• Iron oxide pigment production
• Cement processing
• Chemical synthesis
• Soil stabilization

Difference Between Ferrous Sulfate Monohydrate and Heptahydrate

Ferrous Sulfate Monohydrate (FeSO₄·H₂O) contains approximately 30% iron and is more concentrated.

Ferrous Sulfate Heptahydrate contains around 22% iron and is more widely used due to lower cost and easier handling.

For high-intensity agricultural applications, monohydrate may be preferred. For general fertilizer and water treatment use, heptahydrate is highly efficient and cost-effective.

Why Choose Turkey as a Ferrous Sulfate Supplier?

• Competitive bulk price
• Short transit time to Europe & Middle East
• Strong steel industry raw material base
• Flexible packaging options
• Reliable export logistics
