Description
What is Non-Ferric Aluminum Sulfate Granular 16%?
Non-Ferric Aluminum Sulfate is a refined inorganic chemical with the formula Al₂(SO₄)₃. It is made by reacting bauxite or aluminum hydroxide with sulfuric acid and further purifying the solution to remove iron impurities. The result is a granular white to off-white solid that is free-flowing, easy to store, and simple to dose into treatment systems.
The granular form is preferred in many operations for its dust-free handling and uniform dissolution in water, offering a cleaner and more efficient alternative to powdered or liquid variants.

Key Applications
1. Municipal Drinking Water Treatment
Non-Ferric Aluminum Sulfate is widely used in coagulation and flocculation processes to remove suspended solids, turbidity, and bacteria from drinking water. Its iron-free composition ensures the water remains crystal clear without causing discoloration.
2. Paper and Pulp Industry
Used as a sizing and retention aid in papermaking, this coagulant enhances paper strength, texture, and brightness, making it suitable for high-grade white and colored paper production.
3. Textile Industry
Non-Ferric Alum is essential in dyeing and printing processes as a mordant that ensures consistent and true color shades. The absence of iron prevents unwanted staining or color shift.
4. Industrial and Effluent Water Treatment
Its high coagulation efficiency helps remove impurities and reduce chemical oxygen demand (COD) in industrial wastewater, especially in food processing, petrochemicals, and metal industries.

Handling and Safety
Although Non-Ferric Aluminum Sulfate is generally considered safe for industrial and municipal use, proper handling is necessary. Always wear protective gloves, goggles, and masks when handling the product. Store it in a dry, well-ventilated area, away from moisture and incompatible materials. Refer to the Safety Data Sheet (SDS) for detailed information.
Conclusion
Non-Ferric Aluminum Sulfate Granular 16% (Non-Ferrous) is a versatile, high-performance coagulant that supports clean water, brighter paper, and more consistent dyeing. Its high alumina content, minimal iron levels, and easy-to-use granular form make it an excellent solution for industries requiring precision and purity. Whether used in water treatment plants, textile mills, or paper factories, this non-ferrous alum offers reliable performance with environmental safety in mind.
