  • Plasma-based methods and systems for treating waters with high electrical conductivity and/or low surface tension
    Patent number: 11027990
    Abstract: An electrical discharge plasma reactor system for treating a liquid, the reactor system including: a reactor chamber configured to hold the liquid and a gas; a discharge electrode disposed within the reactor chamber, wherein the discharge electrode is disposed within the gas; an opposing electrode disposed within the gas within the reactor chamber; one or more gas diffusers disposed within the liquid, wherein the one or more gas diffusers is configured to induce the generation of a layer of foam on a surface of the liquid in a plasma-contact region; and a power supply connected to the discharge electrode and/or the opposing electrode, the power supply configured to induce the discharge electrode and the opposing electrode to generate plasma in the plasma-contact region.
    Type: Grant

    Date of Patent: June 8, 2021
    Assignee: Clarkson University
    Inventors: Selma Mededovic, Thomas Holsen
  • Enhanced contact electrical discharge plasma reactor for liquid and gas processing
    Patent number: 10357753
    Abstract: An electrical discharge plasma reactor system for treating a liquid, a gas, and/or a suspension. The reactor system includes a reactor chamber configured to hold the liquid and a gas, a discharge electrode disposed within the gas of the reactor chamber, a non-discharge electrode disposed within the liquid, a gas diffuser disposed within the liquid and configured to induce the generation of a layer of foam on the surface of the liquid in a plasma-contact region, and a power supply connected to the discharge electrode and configured to induce the discharge electrode to generate plasma in the plasma-contact region.
