Aluminium sulphate purified

Purified aluminium sulphate is typically available with assay purity of around 98% or more. It is commonly supplied in the form of aluminium sulphate hexadecahydrate (Al2(SO4)3·16H2O) and is used as a flocculating agent in water purification, wastewater treatment, paper manufacturing, and other industrial and laboratory applications. The purified grade usually has very low impurities, such as chloride below 0.01% and ammonia below 0.05%, ensuring high quality and consistency.
