is being developed. This simulation will map theoretical voltage and current distributions within the apparatus shown in Figure 1. These data will then be used to calculate local power release rates and temperatures in the apparatus. This computer simulation is needed to optimize the electrode and orifice geometry and to plan for higher capacity soil washing units. In the future, the cost of soil washing by this technology will be much cheaper than today by optimization using computer simulations. References (1) Krishnan, R., H.W. Parker and R.W.
