If you're referring to potash alum (Potassium alum), that's a different compound from aluminum sulfate. Let me know if you need its composition instead.

Versatile Applications Across Industries

Alum Sulphate is valued for its astringent properties and effectiveness as a coagulating agent in water treatment, helping clarify and purify water. Its utility extends to paper manufacturing, dyeing, tanning leather, and fireproofing textiles, making it a cornerstone in various industrial processes. The product's stable chemical profile ensures consistency in industrial outputs.

Robust Quality and Safety Standards

Formulated to conform with IS 260:2001 specifications, Alum Sulphate is available in industrial and technical grades. It contains a minimum of 16% Al2O3 and a maximum insoluble matter of 0.5%. The compound is non-poisonous but may cause irritation-safety precautions, such as gloves and goggles, are recommended during handling to ensure user safety.

FAQ's of Alum Sulphate:

Q: How is Alum Sulphate typically used in water treatment processes?

A: Alum Sulphate acts as a coagulating agent in water treatment, binding with impurities to form flocs which are then easily removed, resulting in clearer, safer water.

Q: What are the main benefits of using Alum Sulphate in paper manufacturing?

A: It serves to improve paper quality by enhancing sizing and retention of fibers, resulting in stronger and smoother paper products.

Q: What safety precautions should be observed when handling Alum Sulphate?

A: It is advisable to wear protective gloves and safety glasses to prevent skin and eye irritation due to its astringent properties. Work in a ventilated area and avoid direct contact.

Q: Where should Alum Sulphate be stored for optimal stability?

A: Store Alum Sulphate in a cool, dry, and well-ventilated location to maintain its stability and effectiveness for up to 24 months.

Q: What is the standard packaging for Alum Sulphate and can it be customized?

A: Alum Sulphate is generally supplied in 25 or 50 kg HDPE bags, but packaging can be customized according to customer requirements.

Q: When does Alum Sulphate start to decompose, and what is its melting point?

A: Alum Sulphate decomposes at approximately 92.5C, and because it breaks down before boiling, no true boiling point applies.

Q: What grades and purity levels are available for Alum Sulphate?

A: Alum Sulphate is available in industrial and technical grades with purity levels of 98% or higher, and compositional specifications-such as Al2O3 content-can be customized to client needs.
