Product Description
Aluminium Sulphate (Al2(SO4)3) is a white crystalline inorganic chemical used predominantly as a coagulating agent in water treatment processes. It effectively removes suspended solids and impurities from water, improving clarity and quality. It is also employed as a sizing agent in paper manufacturing to enhance paper properties and as a mordant in textile dyeing. Aluminium Sulphate is valued for its high solubility, cost efficiency, and versatility, serving industries such as water treatment, paper production, textiles, mining, and chemical manufacturing across East Africa.
