Aluminium in drinking water: An overview SSWM

2018-2-12  Al-based coagulants such as aluminium sulphate (Al 2 (SO 4) 3) (better known as alum) or polyaluminium chloride (PACl) are commonly used in drinking water treatment to enhance the removal of particulate, colloidal, and dissolved substances via coagulation processes. The treatment of surface water with aluminium sulphate has been in operation for over a hundred

Aluminum (Al) and water Lenntech

Adding aluminum sulphate and lime to water causes aluminum hydroxide formation, which leads to settling of pollutants. Hydroxide is water insoluble, therefore only 0.05 ppm dissolved aluminum remains. This is below the legal limit for drinking water of the World Health Organization (WHO), of

Alum an overview ScienceDirect Topics

Alum yields about 13% alumina (Al 2 O 3) on cotton.Addition of alkali to alum solution produces basic aluminium sulphate, which is used as a mordant. For mordanting 10. kg of cotton, 1 kg of alum and 0.5 kg of sodium hydroxide are dissolved in 200 l of water to give basic aluminium sulphate of required strength.. As stated above, two different methods are employed for mordanting cotton with
