Use:
Aluminum sulfate is mainly used as paper sizing agent and flocculant for drinking water, industrial water and wastewater treatment, or the production of artificial gems and other aluminum salts, such as ammonia alum, potassium alum, refined aluminum sulfate raw materials. In addition, aluminum sulfate is also widely used in high quality clarifying agent, oil deodorization and decolorization agent, concrete waterproof agent, advanced paper forging white, titanium dioxide film treatment and catalyst carrier production.
