Aluminum sulfate (chemical formula: Al2(SO4)3) is a widely used industrial reagent that is often confused with alum. Aluminum sulfate is commonly used as a flocculant in purified drinking water and sewage treatment equipment, and is also used in the paper industry. Under natural conditions, aluminum sulfate is almost not in the form of anhydrous salts. It forms a series of hydrates, of which aluminium sulphate hexahydrate is the most common. Aluminum sulfate is also an effective mollusk insecticide, killing Spanish slugs.
