TA202D-II has high operating capacity and excellent regeneration efficiency, especially for high FMA (free mineral acids) feed water. It is also recommended to use for the demineralization system where amine odor is undesirable. In chloride form, TA202D-II also could be used to remove alkalinity and organics such as fulvic and humic acids.
