Aluminum sulfate (Chemical formula Al2 (SO4) 3, formula weight 342.15), White orthorhombic crystalline powder, Density1.69g / mL (25 ℃) [1]. In the paper industry as rosin, wax emulsion sizing precipitating agent, Water treatment in as flocculants, retention aids can be made within the foam fire extinguisher, manufacture alum, white aluminum raw materials, oil bleaching, deodorant, some drugs and other materials. It is also the manufacture of artificial stones and advanced ammonium alum.
Approximately 50% of the total output of aluminum sulfate largest Uses for papermaking, is the second largest Uses flocculant in drinking water, industrial water, and Industrial waste water treatment, approximately 40% of total production of aluminum sulfate. When water is added to this type of aluminum sulfate, you can generate colloidal, precipitated and can absorb bacteria, colloidal suspensions and other aluminum hydroxide flakes for use in drinking water Water treatment can control the color and taste.
