Product Overview

Zinc Sulphate is an essential inorganic compound widely used in agriculture, pharmaceuticals, water treatment, and industrial applications. It is available in two forms: Zinc Sulphate Monohydrate (ZnSO₄·H₂O) and Zinc Sulphate Heptahydrate (ZnSO₄·7H₂O). Both forms serve as a vital source of zinc, an essential micronutrient for plant growth, animal health, and industrial processing.

Industrial Applications

1. Agriculture & Fertilizers

• Used as a micronutrient fertilizer to correct zinc deficiency in crops.
• Enhances plant growth, chlorophyll production, and overall yield.
• Applied via soil application, foliar spray, or fertigation.

2. Animal Feed Supplements

• Added to animal feed as a zinc supplement to support growth, immune function, and metabolism.
• Prevents zinc deficiency disorders in livestock and poultry.

3. Pharmaceuticals & Healthcare

• Used in the production of medicines, dietary supplements, and antiseptics.
• Supports immune system function and wound healing.

4. Water Treatment

• Acts as a coagulant in wastewater treatment to remove impurities.
• Used to control algae growth in water reservoirs and cooling towers.

5. Industrial Applications

• Employed in electroplating to enhance corrosion resistance.
• Used in textile processing as a mordant in dyeing and finishing.

Differences Between Zinc Sulphate Monohydrate & Heptahydrate

• Zinc Sulphate Monohydrate (ZnSO₄·H₂O) contains a higher zinc concentration (≥ 33%), making it more efficient for agricultural use.
• Zinc Sulphate Heptahydrate (ZnSO₄·7H₂O) has a higher water content, making it easier to dissolve but with a lower zinc percentage (≥ 22%).
