Aluminium Sulphate

Aluminium sulfate, alternatively spelled either Aluminium or sulphate, is a chemical compound with the formula AI2 (SO4)3. It is soluble in water and is mainly used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing.


Aluminium sulfate is used in water purification and as a mordant in dyeing and printing textiles.

Aluminium sulfate is sometimes used to reduce the PH of garden soil, as hydrolyzes to form the aluminum hydroxide precipitate and a dilute sulfuric acid solution.

In the construction industry, it is used as waterproofing agent and accelerator in concrete.

Another use is a foaming agent in firefighting foam.

It also used in styptic pencils, and pain relief from stings and bites.

It can also be very effective as a molluscicide.

It is used in dentistry (especially in gingival retraction cords) because of its astringent and hemostatic properties.
