Uranium Removal Systems. Uranium removal systems consist of resin that removes uranium without the need for regeneration. The resin has a finite capacity that is dependent on the volume of water and the amount of uranium present in the water. Once the media reaches its maximum capacity, the resin is removed and must be sent to a nuclear waste site.

Ion Exchange (IX) is a method of removing undesirable metallic salt ions from water by exchanging them with other ions attached to a media or resin. This chemical process occurs because ions have differing affinities for the resin and these ions will replace ions with less attraction as they flow over the media.

Key Facts. Before its use in a nuclear reactor, a series of processing steps converts mined uranium ore into ceramic pellets, which are loaded into fuel rods.; Ore mined from open-pit and underground mines travels to a conventional mill. Solvents or ion exchange processing removes the uranium, resulting in uranium oxide, or yellowcake, which is then filtered, dried and packaged.
