What is Aluminium Sulphate?

Aluminium sulphate is a chemical compound with the formula Al2(SO4). It is a double salt, also known as an alum, following the formula AB(SO4)2.12H20 where both A and B are aluminium. Other hydrated forms also include hexadecahydrate and octadecahydrate.

Anhydrous aluminium sulphate is a white crystalline solid that occurs naturally near volcanoes or burning coal-mining dumps. This is an extremely rare mineral called mineralmillosevichite.

Uses of Aluminium Sulphate

Aluminium sulphate is well-suited to a variety of industrial applications. From water purification to textiles and construction, it is a versatile compound that finds many different uses in everyday life.

Purification of Drinking Water

Alternatively spelt aluminium sulfate, aluminium sulphate is most commonly used as a flocculating agent in the process of water purification. When added to water, aluminium sulphate causes impurities to bind together. This forms larger coagulates which settle at the bottom of the water before being removed by filtration.

Other Applications

In addition to being used in water treatment plants, aluminium sulphate has many other applications. It is used:

  • As a mordant in the textile industry
  • In soil to lower the pH
  • As a waterproofing agent
  • In construction as an accelerator in concrete
  • To provide relief from bites and insect stings
  • As an effective molluscicide
