(333j) A Simplified Mathematical Model Of An Ek Cell To Assess The Influence Of Buoyancy Driven Flows On Removal Efficiency

Soil clean up embraces a large family of approaches based on the fundamental principles applied in the operation. For example, EK soil remediation, identified as a versatile technology that can be applied to heavy metal as well as hydrocarbons, has a family of at least seven sub-technologies (i.e. Cation Selective Membrane, Ceramic Casting, Lasagna, Electrochemical ion exchange, etc). Although temperature development on the soil matrix has been observed, little effort has been dedicated to demonstrate or document how temperature triggered mechanisms may be used to overcome soil remediation pitfalls. This contribution focuses on the analysis of results obtained by simulation with a simplified mathematical model. The general hypothesis is that there exist an effect of buoyancy driven flows on the over all removal efficiency of contaminant and that the inclination a EK cell may be used to enhance solute transport. To validate the findings, an experimental approach will be outlined. On the overall, the results and conclusions derived from this study are the baseline for the EK cell system modeling. Comprehensive details of key factors are highlighted to illustrate the modeling technique as well as the system representation.
