Publication number: 20040004040Abstract: Economical processes of the present invention are for separation of fluid mixtures to recover desired products using apparatus comprising a plurality of membrane modules disposed in a first product group, a second product group, and optionally one or more intermediate group. Advantageously integrated processes of the invention with the membrane modules in multiple groups are employed for simultaneous recovery of a very pure permeate product and a desired non-permeate product from a mixture containing organic compounds.Type: ApplicationFiled: June 27, 2002Publication date: January 8, 2004Inventors: Craig W. Colling, George A. Huff, John V. Bartels

Publication number: 20040004042Abstract: Apparatus and method for increasing dissolved oxygen levels in a liquid. An oxygenation system (100) includes a liquid source (102) from which liquid is introduced into a piping network (106) by a pump (104). Colloidal minerals are injected into the liquid in a dwell chamber (110). The mixture of liquid and minerals flows into an oxygenator (118) where gaseous oxygen is injected into the liquid. The resulting two-phase flow stream is accelerated to supersonic speeds through a linear flow accelerator (126) comprising a flat Venturi (130) and electromagnets (128) positioned adjacent the flat Venturi. The electromagnets generate an electromagnetic field to exert a force on the two-phase mixture in the direction of the flow. The flow stream then passes through a laminar flow grid (132) to remove turbulence, after which the oxygenated liquid is bottled at a bottling system (134).Type: ApplicationFiled: July 10, 2003Publication date: January 8, 2004Inventors: Darrell J Hadley, Jeffrey D Hadley, William R Rey, Geir O Eriksen

Publication number: 20040004043Abstract: Apparatuses and methods for separating, immobilizing, and quantifying biological substances from within a fluid medium. Biological substances are observed by employing a vessel (6) having a chamber therein, the vessel comprising a transparent collection wall (5). A high internal gradient magnetic capture structure may be on the transparent collection wall (5), magnets (3) create an externally-applied force for transporting magnetically responsive material toward the transparent collection wall (5). The magnetic capture structure comprises a plurality of ferromagnetic members and has a uniform or non-uniform spacing between adjacent members. There may be electrical conductor means supported on the transparent collection wall (5) for enabling electrical manipulation of the biological substances. The chamber has one compartment or a plurality of compartments with differing heights. The chamber may include a porous wall.Type: ApplicationFiled: June 24, 2003Publication date: January 8, 2004Inventors: Leon W.M.M. Terstappen, Gerald Dolan

Publication number: 20040004044Abstract: A water purifier that has a water container, preferably annular in configuration, within which the water to be purified flows in a continuous stream from an inlet to an outlet within a passageway. A UV emitter, external of the container, directs UV radiation through the water passing through the container. The passageway is a thin depth such that the UV radiation travels only a short path in penetrating the water and thus is very efficient. The UV source is located in close proximity to a thin wall of the water container to further enhance the efficiency of the UV energy. By such design, the water flows continuously through the water purifier and is purified by the time it exits through the outlet. There may be a reflective means proximate of on the outer wall of the container that reflects UV energy back toward the water passageway.Type: ApplicationFiled: July 3, 2002Publication date: January 8, 2004Inventor: Jeffrey J.
