  • Optimized flux ERH electrode
    Patent number: 11642709
    Abstract: An in-situ thermal remediation method and a drip system for implementing the method. The drip water system collects data and changes its drip operation to optimize performance of the electrode. Electrical current, drip volume, drip cycle time and change in current are measured as a function of time and adjustments are made to the drip water volume and time between injections to optimize performance based on the observed current performance over time. A specialized screen delivers water where it is needed.

  • Thermal conduction heater well and electrical resistance heating electrode
    Patent number: 10987710
    Abstract: A combination subsurface heating system that incorporates electrical resistance heating and thermal conduction heating with systems disposed within a single borehole. The combination heating system includes an electrically conductive outermost well casing and a heating element that is electrically isolated from the casing but disposed within it or in an adjacent casing but within the same borehole. Each of the two heating components is powered by a separate power source.

  • PFAS REMEDIATION METHOD AND SYSTEM
    Publication number: 20200260533
    Abstract: A method and system to remediate soil containing PFAS compounds and organic carbon. Total organic carbon is reduced by heating the soil at a sufficient temperature and for a sufficient duration to reduce surface effects between the PFAS compounds and the organic carbon to permit evaporation and treatment of the PFAS compounds from the soil. A flexible helical heater is employed to heat the soil.
