Nuclear plants treat their liquid radwaste onsite. Many plants use a specialized radwaste treatment company to process the radwaste and several plants operate their own systems. Some of these original systems include Powdex® precoat vessels followed by ion exchange deep beds. Radwaste processors erect trains of small vessels containing some or all of the following: Granular Carbon, Cation exchange resin, Anion exchange resin, Mixed bed ion exchange, and a polishing cartridge filter housing. A few systems also include reverse osmosis. The standard cartridge filters have been replaced in some cases with a specialty cartridge containing Graver Technologies radionuclide selective media. A Graver product is available to enhance the performance of each phase of radwaste processing.
