Used in water purification systems to remove dissolved ions and impurities, especially in industrial demineralization processes. Effective in separating cations such as calcium, magnesium, and heavy metals from aqueous solutions. Commonly applied in power plants, pharmaceutical manufacturing, and electronics industries where high-purity water is critical. Also utilized in chemical processing for catalyst recovery, product purification, and wastewater treatment to meet environmental discharge standards. Performs well in both continuous and batch operations due to high capacity and physical stability.
