Aluminium sulfate is a widely used industrial reagent, usually with alum confusion. Alum aluminum sulfate and potassium sulfate is the salt and aluminum sulfate is a single salt. Salt and salt, by more than two single salt composition, in the solution for single ionization of salt ions. Aluminum sulfate was used as flocculant, used for purification of drinking water and sewage treatment equipment, but also for the paper industry. Under natural conditions, aluminum sulfate almost to the anhydrous salt form. It will form a series of hydrate, wherein the aluminum sulfate sixteen water is the most common. Aluminium sulfate is a kind of very effective mollusks insecticides, Spanish slugs ( Spanish slugs). Aluminum sulfate used in water purification and in textile printing and dyeing as a medium. In water purification, it makes impurity condensation, easier to sedimentation and filtration. When dissolved in a neutral or slightly alkaline water, produce colloidal precipitation of aluminium hydroxide, Al ( OH) 3. In printing and dyeing cloth, aluminum hydroxide gel that dye more easily attached to the plant fiber. Aluminium sulfate is also used to adjust the soil pH value, because it is hydrolyzed to generate aluminium hydroxide and sulfuric acid in dilute solution.
