Use of aluminum sulphate
Aluminium sulphate is used in water purification and as a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate. They can then be removed as the particulate settles to the bottom of the container or more easily filtered. This process is called coagulation or flocculation.
