Aluminium Sulfate is white lustrous crystalline, granular or powder. Stable in the air, soluble in water, insoluble in ethanol, acidic solution. Aluminium sulfate is used in water purification and for chemical phosphorus removal from wastewater. It causes suspended impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out) more easily. This process is called coagulation or flocculation.
