Patent number: 7804077Abstract: The invention relates to the confinement of an alloy formed of actinide transuranic radioactive wastes and beryllium metal within a neutron moderating and reflecting apparatus to cause accelerated destruction (burning) of the actinide wastes. Waste actinides, including plutonium, neptunium, americium, and curium, emit alpha particles by radioactive decay. The alpha particles are converted into neutrons by the beryllium through an alpha-neutron (alpha, n) reaction. The neutrons developed by the alpha, n reaction are moderated by a surrounding layer of graphite, which allows the slowed neutrons to cause additional fission or decay events within the waste actinide alloy. This process is passive because the alpha particles that initiate the actinide burning are an intrinsic physical property of the actinides.Type: GrantFiled: October 10, 2008Date of Patent: September 28, 2010Assignee: Neucon Technology, LLCInventors: Laurence Danese, Alan Harvey Wells

The systems and methods include an optimized relationship between the hydraulic loading, zeolite mesh size, distribution of zeolite mesh sizes and zeolite bed volume expansion to provide a highly effective sorption column that resists clogging while increases capacity.Type: GrantFiled: October 28, 2004Date of Patent: February 5, 2008Assignee: WRT International LLCInventors: Charles S. Williams, Jody Kelso, David Jones

Patent number: 7229559Abstract: Hydrophobic polymer particles (e.g., granules or fragments) employed as filter media, e.g., for filtering runoff water, include an antimicrobial compound on exterior surfaces and can reduce proliferation of microbial organisms as well as sorb chemical contaminants from the water. By employing this dual decontamination action, filter systems employing such particles can improve the quality of runoff water (or other contaminated water streams) and reduce the risk presented by potentially harmful organisms.Type: GrantFiled: February 27, 2004Date of Patent: June 12, 2007Assignee: AbTech Industries, Inc.Inventor: Rodolfo B.

Patent number: 7226535Abstract: The invention relates to a method of distributing a liquid in the fluid bed of an up-flow or a down-flow fluid bed reactor. The invention provides efficient distribution and plug flow like fluid flow through the fluid bed where turbulence and/or back-mixing of the fluid are minimized. In accordance with the invention a fluid bed system for use in treating a fluid by contacting the fluid with a solid phase media is provided and the system includes a reactor chamber adapted to contain the solid phase media and at least one fluid distribution means adapted to distribute and/or deliver the fluid to be treated among the particles of the medium.Type: GrantFiled: September 13, 2005Date of Patent: June 5, 2007Assignee: Upfront Chromatography A/SInventors: Jurgen Hubbuch, Timothy J.
