Patent number: 7183453Abstract: A system and method is provided for producing a safely disposable end product from waste matter containing undesirable materials, such as infectious, biohazardous, hazardous, or radioactive elements. The method comprises the steps of providing a highly basic solvent, immersing the waste matter containing the undesirable materials within the highly basic solvent, and heating the solvent. The waste matter containing the undesirable materials is allowed to remain within the solvent until digested, thereby forming a solution void of any infectious or biohazardous elements and/or containing a decreased concentration of radioisotope.Type: GrantFiled: July 23, 2002Date of Patent: February 27, 2007Assignee: Waste Reduction by Waste Reduction, Inc.Inventors: Joseph H. Wilson, Gordon I. Kaye, Robert L. Hahn, Peter B. Weber, Kevin A. Morris

Patent number: 7160472Abstract: Methods and systems for treating a waste stream in a waste treatment system involve performing a unit process of the waste treatment system by contacting the waste stream with oxyhydrogen-rich gas generated on-site by an oxyhydrogen gas generator that implements water dissociation technology. In a preferred embodiment, the oxyhydrogen gas generator involves applying a pulsed electrical signal to a series of closely-spaced electrodes that are submerged in the waste stream to produce oxyhydrogen-rich gas from a water component of the waste stream. Operation of the oxyhydrogen gas generator in the waste stream may accomplish one or more unit processes for waste treatment, such as conditioning, stabilization, thickening, and dewatering, among others. At least a portion of the oxyhydrogen-rich gas can be conveyed for a second use in the waste treatment system, such as a source of combustible fuel for incineration or power generation, for example.Type: GrantFiled: November 19, 2003Date of Patent: January 9, 2007Assignee: Xogen Technologies Inc.Inventors: Dave Van Vliet, Herbert Wallace Campbell, Stephen Barrie Chambers

Patent number: 7087805Abstract: A method and apparatus for neutralizing biological and/or chemical warfare agents using an ozone-containing solution. The ozone-containing solution is produced by combining ozone-containing gas with an ozone vehicle, such as an organic solution. The ozone-vehicle prolongs the shelf life of the ozone to allow for extended periods of storage. A storage container is used to store the ozone-containing solution and facilitate its transportation to an environment contaminated by the biological and/or chemical warfare agents, or near a potential site for biological or chemical attack. The ozone-containing solution is drawn out of the storage container to apply it to a contaminated environment.Type: GrantFiled: October 22, 2002Date of Patent: August 8, 2006Assignee: STERIS Inc.Inventors: Michael A. Centanni, Daniel J. Subach, Iain F. McVey

Patent number: 7060236Abstract: A continuous and regenerative process for removal and destruction of VOC from effluents is disclosed. The process employs two fixed bed reactors in series filled with adsorbent/catalyst. The VOC containing effluent is passed over the first reactor for adsorbing VOC, while the second reactor, which is loaded with VOC from the previous cycle is regenerated with part of the treated gas made up with an appropriate amount of air. Just before the VOC breakthrough occurs at the first reactor, the roles of the two reactors are switched. The process is characterized by simple design, high VOC removal efficiency, no external heat requirement and low operation cost.Type: GrantFiled: October 21, 2002Date of Patent: June 13, 2006Inventors: Tsoung Y. Yan, Jen-Ray Chang
