ET-DSP™ process description
ET-DSP™ takes advantage of the electrical resistive properties of soil creating conditions of increasing temperatures in an underground formation to a sufficiently high level thereby driving contaminants to separate from soil particles.
Electrodes are installed in shallow wells throughout the contaminated soil and groundwater volume.
The electrode array is connected to a Power Delivery System Unit, that uses standard, readily available three phase power from the grid. The process begins by passing current between electrodes causing the soil temperature to rise. This increased temperature results in the volatilization of contaminant compounds into the vapour phase. The vapour mass can then be removed from the soil with vapour extraction techniques.
Comprehensive computer controls are used to regulate and optimize the thermal response of the target formation.
