A container for treating a fluid with an ion-exchange system is provided. The container includes a housing extending in an upright position between a bottom port and an opposed top port. The housing has an internal chamber. A bottom plate is disposed in the internal chamber above the bottom port and having a plurality of openings defined therethrough. The bottom plate divides the internal chamber between a main chamber and a bottom chamber. The bottom chamber is defined between the bottom plate and the bottom port. A plurality of diffusers extend from the bottom plate into the main chamber. Each one of the plurality of diffusers has a diffuser tube section projecting upwardly from the bottom plate and in fluid flow communication with the bottom chamber. The diffuser tube section has radial openings circumferentially distributed along a length thereof to radially discharge the fluid in the main chamber.

A purification method for spent fuel pool water from nuclear power generation, the method comprising: passing the water at a linear flow velocity of 50 m/h or less through a purification apparatus for the water comprising an ion exchange resin layer and a metal-doped resin layer which is laid at a bed height of 2 cm or more on a surface layer of the ion exchange resin layer wherein the water to be treated is contacted with the metal-doped resin layer to decompose a pro-oxidant contained in the water; and subsequently contacting the water with the ion exchange resin.

A method of producing treated ion exchange resin material includes exposing an enclosed vessel containing ion exchange resin and a pre-treatment solution to high energy radiation. The treated ion exchange resin material has reduced organic impurities or total organic carbon (TOC).

A method for purifying an organic solvent has a first treatment of bringing an organic solvent to be treated into contact with an H-type cation exchanger, and a second treatment of bringing a treated liquid from the first treatment into contact with an anion exchanger and an H-type strongly acidic cation exchanger. According to the present application, the provided method and an apparatus for purifying an organic solvent remove metal impurities of both metal species of monovalent and polyvalent metals in the organic solvent.
