2.Simple Introduction
Aluminum sulfate (chemical formula Al2(SO4)3, formula 342.15), white orthorhombic crystalline powder, density 1.69 g/mL (25 ° C). In the paper industry, as a precipitant for rosin rubber, wax emulsion and other rubber compounds, as a flocculant in water treatment, it can also be used as an internal retention agent for foam fire extinguishers to produce alum, aluminum white raw materials, petroleum decolorization, deodorizer, and some Raw materials for drugs, etc. It is also possible to manufacture artificial gemstones and advanced ammonium alum.

The first major use of aluminium sulphate, which accounts for about 50% of total production, is for papermaking. The second largest use is flocculant in drinking water, industrial water and industrial wastewater treatment, accounting for about 40% of total aluminum sulphate production. When aluminum sulfate is added to such water, it can form a colloidal aluminum hydroxide flake which can adsorb and precipitate bacteria, colloids and other suspended materials, and can be used in drinking water treatment to control the color and taste of water.
