Used in water treatment processes to remove calcium and magnesium ions from high-salinity water, improving water quality and preventing scale formation in industrial systems. Effective in desalination pre-treatment, boiler feedwater purification, and wastewater recycling where high ionic strength would degrade standard resins. Enables efficient ion exchange even in seawater or brine environments, supporting longer equipment life and reduced maintenance in oil and gas, power generation, and marine applications.
