Application

1.Water treatment
Aluminium sulfate is used in water purification it causes impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out)
2.Textile agent
In dyeing and printing cloth, the gelatinous precipitate helps the dye adhere to the clothing fibers by rendering the pigment insoluble.
3.Others
Aluminium sulfate is sometimes used to reduce the pH of garden soil, medicine and food,etc.
