How does ET-DSP™ work?
(Top) This process involves heating soil within and across both saturated and unsaturated zones by passing electrical current via electrodes placed at calculated depths and distances. A moderate volume of water is circulated through the electrodes to achieve both conductive and convective heating. Using a customized computer program, the quantity, timing, and location of power application is monitored and controlled on a continuous basis. Power to each electrode as well as water injection can be modified individually in response to the heterogeneous properties throughout a contaminated soil plume. As a result, the heating is precise, uniform, and efficient but rapid under this process.
