  • Publication number: 20020076370
    Abstract: There is disclosed an apparatus and method using meta-stable radicals to treat air and porous solid mediums contaminated with organic material including bacteria, viruses, microbes and chemical contaminants. In a preferred embodiment, the meta-stable radicals are generated using a pulsed corona discharge apparatus. Further, in a most preferred embodiment, the meta-stable radical mixture includes ozone.

  • Patent number: 6080362
    Abstract: A method to disinfect a porous solid medium, such as soil, includes the steps of embedding a plurality of electrodes into the porous solid medium and applying a plurality of alternating current voltage pulses between the electrodes. The voltage pulses have a peak voltage of at least 10 kilovolts and are of an intensity and duration effective to generate a quantity of ozone. The ozone is produced in quantities sufficient to disinfect the porous solid medium.

  • Patent number: 5756054
    Abstract: There is disclosed an ozone generator having enhanced ozone generating capabilities. A cryogenic stream of oxygen is irradiated with a high voltage electron beam that converts a portion of the oxygen into ozone. When the oxygen stream is liquid, conversion rates of up to 33% are achieved. Separation of ozone from oxygen is achieved by exploiting physical properties. In one embodiment, a gaseous mixture is at a temperature between 90 K and 161 K. A condenser coil condenses the ozone to a liquid. The ozone may be directed to a reaction chamber containing a surface increasing medium, such as porous inert beads, to remediate air borne biological and organic contaminants.

  • Patent number: 4663567
    Abstract: An ionizable material is injected in the shape of concentric jet and cylindrical column of gases from a cathode-nozzle toward an anode and subjected to a very short, high voltage pulse of electrical current having sufficient magnitude to create a high magnetic field which implodes the cylindrical column of ionizable material and compresses the central jet of ionizable material to a very dense plasma that is relatively stable longitudinally that can be used as a gain medium for a long wave length X-ray laser.
