Aluminum Sulfate 'or' Non-Ferric Alum Lumps

Aluminum Sulfate, also known as Non-Ferric Alum Lumps, is a high-purity, iron-free chemical compound primarily used as a coagulant in water treatment to remove suspended particles, a sizing agent in paper manufacturing, and a mordant in textile dyeing. It appears as white, crystalline lumps or powder and is valued for its clarity-enhancing properties, making it suitable for applications like high-grade paper and cosmetics where iron content would be undesirable.

Characteristics Aluminum Sulfate 'Or' Non-Ferric Alum Lumps:

Purity: It is a "non-ferric" form, meaning it has very low or no iron content, resulting in a white or off-white color.

Form: It is often sold in solid, crystalline "lumps" that can be crushed into powder.

Chemical Formula: The basic chemical formula is Al₂(SO₄)₃.

Uses and Applications of Aluminum Sulfate 'Or' Non-ferric Alum Lumps:

Water Treatment: It acts as a coagulant to clump together impurities and suspended particles in both municipal and industrial water, facilitating their removal through filtration.

Paper Manufacturing: It is used in the sizing process to improve the strength and quality of paper.

Textile Industry: It Functions as a mordant, helping dyes to fix and adhere to fabric.

Other Applications:

Gardening: It can be used to adjust and improve soil pH levels.

Cosmetics & Personal Care: Its astringent properties make it suitable for use in some cosmetic products.

Other Industrial Uses: It is found in leather tanning, as a component in fire-resistant materials, and for clarifying oils and fats.
