Abstract
A treatment system passes feed water containing a contaminant such as perchlorate through a bed of strong base anion exchange resin that has been placed in a form (e.g., in sulfate form) to selectively capture the contaminant while passing other ions (e.g., nitrate) that may also be present in the water. The bed may include a carousel, and the exhausted upstream portion of the resin may efficiently be disposed of by incineration, or may be rotated out for regeneration.
