Description

What is Non-Ferric Aluminum Sulfate Powder 17%?

Non-Ferric Aluminum Sulfate (chemical formula: Al₂(SO₄)₃) is an inorganic salt composed of aluminum and sulfate ions. The 17% concentration refers to the minimum Al₂O₃ (alumina) content in the product. Unlike ferric aluminum sulfate, this non-ferrous version is free from iron, resulting in a pure white or off-white powder that is ideal for color-sensitive processes.

This powdered form is fine, free-flowing, and easily soluble in water, making it easy to handle and apply in treatment systems.

Key Applications

1. Drinking Water Treatment

Non-Ferric Aluminum Sulfate is used extensively in municipal water treatment plants for coagulation and flocculation. It binds with suspended solids and impurities, making them easier to filter and remove. Its iron-free composition ensures the water remains colorless and free of staining, which is particularly important in domestic water supply.

2. Paper Manufacturing

In the paper industry, Non-Ferric Alum is used as a sizing agent to improve paper quality and strength. Its high purity helps produce brighter, whiter paper, free from discoloration that can result from iron contamination.

3. Textile and Dyeing Industry

Used in textile processing, especially in dye fixing and mordanting, where iron-free alum ensures true dye color and avoids staining or hue alteration.

Benefits of Non-Ferric Aluminum Sulfate Powder 17%

• High purity and low iron content make it ideal for color-sensitive processes

• Consistent coagulation performance in water and wastewater treatment

• Cost-effective and widely available

• Fast dissolution and easy to dose in powdered form

• Environmentally friendly and compatible with eco-safe discharge standards

Safety and Handling

While Non-Ferric Aluminum Sulfate is non-toxic and safe for standard industrial use, it should be handled with care. Use gloves, goggles, and masks when handling the powder to avoid irritation. Store in a cool, dry, and ventilated area, away from moisture and reactive chemicals.

Conclusion

Non-Ferric Aluminum Sulfate Powder 17% (Non-Ferrous) is a versatile, high-quality coagulant that offers excellent performance in water purification, paper manufacturing, and textile processing. Its iron-free nature ensures clarity, brightness, and consistency across various applications. Whether you’re improving municipal water quality or enhancing industrial output, this non-ferrous alum powder stands out as a reliable, effective, and clean chemical solution.
