  • Patent number: 10580542
    Abstract: One aspect of the invention provides a system for treating wastestream, particularly a liquid or aqueous radwaste, for safe disposal and, in final processing, converting it into one or both forms including an aqueous form for safe discharge to the environment and a solidified form for safe disposal. Another aspect provides the capacity to employ a step where a specific target element strategy can be set up synchronizing sorbent substance choices and multiple recycle options to remove target substances from wastestream as a part of its Sorption or Powder Sorbent Isotopic Reduction step (II). Other steps cooperate with Sorption step (II) including Oxidation (I) to inactivate or destroy existing chelants, Solid-Liquid separation (III), and Selective Ion Exchange (IV) to deliver the wastestream to final processing.

  • Patent number: 8114004
    Abstract: A Method and Device for solidification of waste liquids and fluids is disclosed, which is particularly well suited to processing radioactive waste fluids. Set forth is a receiving unit or subassembly for housing solidification agent, and one or more manifold units or subassemblies positioned within the receiving unit for providing waste fluid. The subassemblies operate in relation to each other to provide, position and mix solidification agent or polymer with waste fluid so that a dirt-like polymerized waste product is produced and positioned in the container for removal or later safe shipment or storage. Mathematical relationships, in preferred embodiments or aspects are utilized in determining number and sizing of manifold openings, and pressure of waste to be provided, to meet the requirements of waste fluids to be transported through these openings into the receiving unit.

  • Patent number: 7645387
    Abstract: Method of maximizing resin utilization and optimizing reverse osmosis performance to polish an aqueous or radwaste fluid. The method provides resin scavenging of targeted isotopes and exposes filter media and resin to a higher influent activity concentration to enable higher waste loading and longer life of resin while protecting downstream reverse osmosis system from high concentration of contaminants. An aqueous waste feedstream is processed through steps of filtering, demineralizing, and reverse osmosis; and the feedstream is separated into permeate and reject streams for recycling and evaluation, respectively. The permeate stream is recycled in ways that permit it to return to a supply area for recycle reuse or discharge.

  • Publication number: 20080004477
    Abstract: A Method and Device for solidification of waste liquids and fluids is disclosed. The invention is particularly well suited to processing radioactive waste fluids; and employs a metered polymer supply assembly and metered waste supply assembly, which have a prescribed positional orientation in relation to themselves and a container. These assemblies operate in relation to each other to meter, mix and position a solidification agent or polymer with a waste fluid so that a dirt-like polymerized waste product is produced and positioned in the container for safe shipment or storage. The waste supply assembly in a preferred embodiment is provided with a novel waste trough. Prescribed mathematical relationships for determining the trough length, and the cross-sectional dimensional relationship of the polymer chute of the invention in relation to the cross-sectional dimensional magnitude of the waste trough is set forth.
