  • Method and apparatus for non-thermal pasteurization
    Patent number: 6562386
    Abstract: A method and apparatus are provided for at least partially sterilizing a liquid that has pathogens living in the liquid. The liquid comprising living pathogens is placed in a reaction volume, and a non-thermal plasma is generated within the reaction volume to thereby kill at least a portion of the pathogens within the liquid.
    Type: Grant
    Filed: May 7, 2001
    Date of Patent: May 13, 2003
    Assignee: Regents of the University of Minnesota
    Inventors: R. Roger Ruan, Hongbin Ma, Mingliang Zhang, Paul L. Chen, Duane Oyen

  • Odor removal system and method having ozone and non-thermal plasma treatment
    Patent number: 6451252
    Abstract: An odor removal system includes an odorous gas inlet, a treated gas outlet and a gas treatment flow path from the odorous gas inlet to the treated gas outlet. A mixer is coupled in series with the gas treatment flow path and has an ozone inlet coupled to an ozone outlet of an ozone generator. A non-thermal plasma reactor is also coupled in series with the gas treatment flow path.

  • Dielectric barrier discharge system and method for decomposing hazardous compounds in fluids
    Patent number: 6146599
    Abstract: A dielectric barrier discharge system includes first and second non-thermal plasma reactors which are coupled together in series. The first reactor includes a first surface discharge electrode which defines a first discharge path along the first surface discharge electrode. The second reactor includes second and third electrodes which are separated by a gap and define a second discharge path which extends across the gap. The system can be used to decompose hazardous compounds in a liquid or a gas, such as in power plant flue gases.
