Widely used in water treatment processes, this chemical acts as a coagulant to remove suspended particles and impurities. It helps clarify drinking water and treat wastewater by promoting the aggregation of fine particles into larger flocs that can be easily filtered or settled out. Commonly applied in municipal water purification plants and industrial effluent treatment systems. Also utilized in paper manufacturing to improve the sizing and strength of paper products. It assists in the retention of fillers and fibers during the papermaking process, enhancing the quality and durability of the final product. In agriculture, it is used to lower soil pH, especially in alkaline soils, making them more suitable for acid-loving plants. It provides a source of aluminum and sulfate, which can influence nutrient availability and plant growth. Additionally, it finds use in the textile industry as a mordant in dyeing processes, helping fix dyes to fabrics for improved colorfastness. Also applied in fireproofing materials and in the production of other aluminum compounds.
