Patent number: 5958196Abstract: Planar electrodes include a carbon fiber cloth which is woven or braided from a plurality of PAN-derived carbon fibers and which is mounted in a frame. The frame is preferably made of an inert plastic material such as TEFLON, PVC, or DELRIN and the carbon fiber cloth is preferably affixed to the frame with metal strips and fasteners. The metal strips are preferably titanium or a noble metal and the fasteners are preferably made of the same metal as the strips. The metal strips form a low impedance electrical contact with the carbon fiber cloth and enable the electrode to be coupled to a wire lead or electrical contact for use in an electrochemical circuit. According to a second embodiment, the carbon fiber cloth is sandwiched between two metal frames. According to a third embodiment, the carbon fiber cloth is sandwiched between two plastic frames with conductive foil strips or titanium strips forming an electrical contact with the carbon fiber cloth.Type: GrantFiled: January 22, 1997Date of Patent: September 28, 1999Assignee: Upscale Water Technologies, Inc.Inventors: Mark Lubin, Sjef Otten

Patent number: 5935392Abstract: A carbon fiber electrode is coated with a noble metal oxide to create a noble metal oxide electrode with a very large surface area. According to a presently preferred embodiment, the noble metal oxide is iridium oxide. A method of making the electrode includes preparing a solution of iridium chloride and isopropyl alcohol, dipping a carbon fiber electrode into the solution, drying the electrode in the presence of nitrogen and heat, and heat treating the electrode in the presence of oxygen. An apparatus for removing nitrates from water includes an electrochemical flow cell through which the aqueous solution containing nitrates flows or a holding tank cell into which the solution is introduced and then released after processing, and an electrode system including an anodic iridium oxide coated carbon fiber electrode as described above, a carbon fiber cathodic electrode and a reference electrode.Type: GrantFiled: November 27, 1996Date of Patent: August 10, 1999Assignee: Upscale Water Technologies, Inc.Inventors: Mark Lubin, Sjef Otten

Patent number: 5614078Abstract: An apparatus for reducing nitrates in an aqueous solution includes an electrochemical cell having a container for containing the aqueous solution containing nitrates, a carbon fiber cathodic electrode, a carbon fiber anodic electrode, and a reference electrode immersed in the aqueous solution, and an electronic control circuit which impresses a voltage across the electrodes causing electrochemical reduction/oxidation reactions on the surfaces of the electrodes. The electrodes are at a potential such that nitrates are reduced to gaseous products, and further such that hydrogen, oxygen, chlorine, an other noxious substances are not produced. The cell may be a flow cell or a holding tank and apparatus of different size and capacity are disclosed. The apparatus is useful in reducing nitrates in any water system and is particularly useful in reducing nitrates in aquatic systems without harming aquatic life.Type: GrantFiled: June 26, 1996Date of Patent: March 25, 1997Assignee: Upscale Technologies, Inc.Inventors: Mark Lubin, Sjef Otten
