Description:
Electrokinetic Soil Processing (or Electrokinetic Remediation) uses two series of electrodes (anodes and cathodes) positioned inside compartments that allow egress and ingress of pore fluids to the porous media. The compartments are filled with water or other process fluids and inserted into contaminated soil. A direct current (DC) is applied across the electrodes. Under such conditions, moist soil acts as an aqueous electrolyte and ions and solution move toward the electrodes. The coupling between electrical, chemical, and hydraulic gradients is responsible for the movement of both contaminants and the processing solution through the soil.
