  • Publication number: 20150380117
    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. Still further aspects of the invention address the recovery and safe handling of substances such as C-14.

  • Publication number: 20130345488
    Abstract: The present Treatment System (10) addresses destruction of general nitrogen based organic (plastic) explosives in wastewater discharge applications and potential recovery of quantities of explosives otherwise lost to the environment. The Invention (10) addresses the problem of such explosive matter entering the environment in one aspect of the invention by treating a wastestream or aqueous substance from a plant containing such matter by a process including selective filtration (16), reverse osmosis (18), crystallization (20) and continuous retained biological treatment (12) to recover a maximum amount of explosive material from the wastestream or aqueous substance, containing organic nitrate explosive matter and related materials prior to discharge to the environment, or for the purposes of recycle, burning or food for the continuously retained biological subsystem when utilized in the invention.

  • Patent number: 7708890
    Abstract: Environmentally protective Method of treating an aqueous radioactive fluid (AF) in a nuclear reactor cycle or radwaste system to selectively capture or remove radioactive isotopes in a reduced quantitative package to minimize radwaste generated and revitalize neutron absorption capacity of nuclear reactor coolant by separately carrying away boron constituents, when B10 is later added.

  • 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.

  • Patent number: RE40943
    Abstract: A method in treating aqueous feedstream in diverse plant site environments is disclosed for improving filter flux rates, cleaning filter media and prolonging useful operative life of media. In preferred embodiments the method is provided with steps for contacting, reacting, pressurizing and equalizing ozone and feedstream within a central area or multiple areas and sustaining high pressure throughout the system to achieve qualitatively and quantitatively improved permeate products, and reject for recycle. The method and system provide an improved cleaning and processing system characterized by an ozone-concentrated, homogeneous single phase liquid conversion of a generated ozone gas mixture and a feedstream source containing organic and inorganic pollutants. The method improves and monitors ozone oxidizing power and reflecting ORP values, and provides further media cleaning and improved oxidation reactions for attack on pollutants on each cycle/recycle operation.
