Operation of a deionizer containing exhausted anion resin, where the principal anionic constituent of the influent is NO/sub 3//sup -/, will result in elution of the other anions from the column. In the moderator system, where the exhausted anion resin contains principally HCO/sub 3//sup -/, Cl/sup -/, and NO/sub 3//sup -/, most of the HCO/sub 3//sup -/ will be eluted before much of the Cl/sup -/ is released. This can be observed in the conductivity record of the effluent, for the conductivity will level off as H/sub 2/CO/sub 3/ is released, and rise with the release of the stronger acid, HCl. This behavior was observed in the miniature purification tests and also in the conductivity record of the P Area deionizers that were run to exhaustion. Operation of exhausted deionizers is to be avoided not only because of the possible release of chloride to the system, but also because they cannot remove chloride from the system. One source of chloride is the Amberlite IRA-400, which is not completely regenerated from the chloride form when purchased.
