The specific function group offers TA202D-II with outstanding operating capacity and excellent regeneration efficiency, especially for high FMA (free mineral acids) feed water. TA202-II is devoid of taste and odor, so it is also recommended to use for the demineralization system where amine odor is undesirable. In chloride form, TA202-II also could be used to remove alkalinity and nitrates.
