Strong base anions
Strong Base Anion (SBA) exchanger containing TypeII quaternary ammoniumgroups are used for dealkalization, deionization, demineralization,desilicizersand organic removal. SBA's have excellent operating capacityand good kinetics even when regenerant levels are comparitively low.
Lanlang ® TA202-II Is a premium grade gel type II strong base anion exchange resin with polystyrene matrix and type II quaternary amine (Dimethylethanolamine) function group in standard Gaussian size distribution. 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.
Water demineralization, dealkalization, nitrates removal.
