Audited Supplier Aluminum sulfate (chemical formula Al2(SO4)3, formula weight 342.15), white orthorhombic
crystalline powder, density 1.69g/mL (25ºC). In the paper industry, it is used as a precipitant for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, and as an internal retention agent for foam fire extinguishers, as raw materials for the production of alum and aluminum white, petroleum decolorization, deodorant, and some Raw materials for medicines, etc. It can also produce artificial gems and advanced ammonium alum. Aluminum sulfate, which accounts for about 50% of the total output, is used as a flocculant in the treatment of drinking water, industrial water and industrial wastewater, and accounts for about 40% of the total output of aluminum sulfate. When aluminum sulfate is added to this type of water, it can produce colloidal aluminum hydroxide flakes that can adsorb and precipitate bacteria, colloids and other suspended solids, which can be used in drinking water treatment to control the color and taste of the water.
