    Abstract: Provided is a method that can remove fission products in a spent electrolyte produced in a dry reprocessing process by an easy operation and can vitrify the fission products easily, the fission products including not only the fission products that generate precipitate but also the fission products that generate no precipitate. A spent electrolyte produced in a dry reprocessing process is subjected to a phosphate conversion processing to obtain a processing target substance; the processing target substance is passed through a separating material 10 including an iron phosphate glass at a temperature of not more than a softening point of the iron phosphate glass in order to remove insoluble fission products included in the processing target substance by filtration with the separating material and to sorb fission products in solution to the separating material for separation; and the iron phosphate glass holding the fission products is used as a waste vitrification material.

  • Publication number: 20110226687
    Abstract: A system and method for uniformly distributing fluids (e.g., washing and in-service) through a filter bed of a filter. The system and method of the present invention can be used with any type of filter that uses media to remove impurities from a fluid. The filter bed can include one or more layers of media. The media can be natural (e.g., sand, gravel, anthracite, etc.) or can be fabricated (e.g., plastic). The filter media can be supported by one or more layers of gravel. Alternatively, the filter media can be supported by a porous plate or other support designed to replace the gravel layers. The present invention includes a system having one or more distribution members configured to uniformly distribute a fluid through a filter bed of a filter. Preferably, the one or more distribution members can be readily installed by relatively unskilled labor in both existing filters and new filters.

  • Patent number: 8002974
    Abstract: A stormwater inlet near an upper edge of a layered filter media vessel is equipped with a distribution header that ensures effective use of the surface area of the filter media by providing plural spaced streams of stormwater thereat, each at a point of impact having its energy dissipated by a layer of material that covers the upper layered filter media surface. The stormwater inflow is metered to control the stormwater pollutant removal process kinetics, thereby slowing the mean free path of the stormwater therethrough and optimizing pollutant capture. The water level within the vessel is height adjustable manually by a pivot arm in the form of a standing column of water coupled to the water within the container. Weep conduits are provided to slowly drain down the standing water in the system between storm events, simplifying maintenance and promoting best removal of pollutants from first-flush storm events. Stormwater pretreatment, e.g. by use of an oleophilic agent or a pH-buffering agent, is provided.
