Aluminum sulfate for water treatment ensures safe drinking water. Municipal water utilities rely on it to purify water by causing impurities to coagulate into larger particles, which then settle and can be easily filtered out. This process improves water quality by removing bacteria and sediment. The same principle is applied in treating process water and in swimming pools, where aluminum sulfate helps reduce cloudiness, making the water cleaner and safer for use.
Aluminum sulfate is also commonly used in the food industry for a variety of purposes and is considered safe when used according to good manufacturing practices. Its water solubility makes it effective as a thickener and emulsifier. Additionally, sodium aluminum sulfate in food is used to remineralize and clarify water in soft drinks and beer, regulate pH levels in vegetables, purify sugar beet juices, control pH and color in wine and liquor, act as a leavening agent in cake mixes, and aid in curdling and thickening cheese.
Aluminum sulfate has a variety of applications beyond water treatment and food. In fabric dyeing, it acts as a dye fixer by helping dyes adhere to cloth fibers, ensuring colors remain vibrant and water-insoluble. In papermaking, it was historically used to adjust the paper's absorbency and ink retention, although synthetic agents have largely replaced it. In the medical field, aluminum sulfate serves as a coagulating agent for treating minor wounds and as an antibacterial component in deodorants. It is also used in vaccines to enhance immune response and in pharmaceutical preparations, such as aluminum acetate ear drops.
