Aluminum polysulfate is widely used in water treatment processes due to its effectiveness as a coagulant. It helps in the removal of suspended particles, organic matter, and other impurities from water, making it clearer and safer for consumption. In the paper and pulp industry, it is utilized as a retention aid and to improve the strength and quality of paper products. It also aids in controlling pitch and resin deposits during the manufacturing process. In wastewater treatment, aluminum polysulfate is employed to treat industrial and municipal wastewater, reducing pollutants and improving the efficiency of the treatment process. Additionally, it is used in the textile industry for dye fixation and improving the color fastness of fabrics. Its ability to bind with dyes ensures vibrant and long-lasting colors on textiles. In construction, it is applied as a concrete additive to enhance the setting time and durability of concrete structures. It also helps in reducing water permeability, making the concrete more resistant to environmental factors. Overall, aluminum polysulfate plays a crucial role in various industries by improving efficiency, quality, and environmental safety.
