Widely used in water treatment processes to remove anions such as nitrate, sulfate, and chloride from drinking water and industrial wastewater. Effective in demineralization systems when paired with cation exchange resins. Commonly applied in the food and beverage industry for deacidification and purification of sugar syrups, juices, and alcoholic beverages. Used in pharmaceutical manufacturing for purification of antibiotics and other bioactive compounds. Also utilized in the recovery of valuable metals from mining effluents and electroplating wastewater by capturing anionic metal complexes. Its macroporous structure provides good mechanical strength and resistance to fouling, making it suitable for treating liquids with high organic content.
