Non Ferric Alum Powder
Non-ferric alum powder, also known as aluminum sulfate, is a white, crystalline powder that is soluble in water. It is a high-purity form of aluminum sulfate, produced without iron impurities, making it ideal for applications requiring high purity, such as paper manufacturing. It is used as a coagulant in water purification and as a sizing agent in paper production.
Key Characteristics:
Appearance: White, crystalline powder.
Solubility: Highly soluble in water.
Purity: Non-ferric, meaning it has very low iron content, making it suitable for applications where iron contamination is undesirable.
Chemical Formula: Al2(SO4)3.
Production: Typically made from aluminum trihydrate and sulfuric acid.
Common Uses:
Water Purification: Acts as a coagulant to remove impurities from drinking water and wastewater.
Paper Manufacturing: Used as a sizing agent to improve the paper's ink receptivity and overall quality.
Textiles: Enhances dye absorption and color permanence in the textile industry.
Distinction from Ferric Alum:
Ferric alum: contains iron impurities, whereas non-ferric alum is iron-free.
Ferric alum: is often sourced from bauxite, while non-ferric alum is derived from aluminum trihydrate.
Non-ferric alum: is preferred for applications where iron contamination is a concern, like in premium paper production.
