Used extensively in water softening processes, removing calcium and magnesium ions to prevent scale formation in boilers and industrial equipment. Commonly applied in demineralization systems for producing high-purity water in power plants and pharmaceutical manufacturing. Employed in food and beverage industries for dealkalization and purification of process water. Also utilized in metal recovery and effluent treatment to remove heavy metal cations from wastewater streams. Its sodium form is preferred for ion exchange applications requiring minimal pH change in the treated solution.
