Aluminium sulfate, commonly known as alum, is widely used in water purification as a coagulant. It works by neutralizing the electrical charges of tiny suspended particles in the water, causing them to clump together into larger, heavier particles (floc) that settle out more easily, making the water clearer. 

Aluminium sulfate, commonly known as alum, is widely used in textile dyeing as a mordant to fix dyes onto fabrics, improving color retention and washfastness. It acts as a bridge, forming a chemical bond between the dye and the fabric, preventing the dye from easily washing out. This process is crucial for achieving desired hues and enhancing the overall dyeing outcome. 

Aluminium sulfate, also known as alum, is used in papermaking as a sizing agent, particularly in conjunction with rosin soap, to control the paper's absorbency and improve its ink-holding properties. While it has been largely replaced by synthetic sizing agents, alum is still used in certain applications, especially when making acidic paper. 

Aluminum sulfate, known as E520 as a food additive, is a firming agent used in some food products like pickles and maraschino cherries. It helps maintain the texture and quality of these foods. It can also be found in baking powders as a slow-acting leavening acid, often in combination with other acids like MCP.
