Specific Energy Requirements in Electrokinetic Remediation

Understanding the scaling-up process is essential for the application of the electrokinetic remediation at field scale, as the technique is site-specific and dependent on the target contaminants. In this paper, a generalized and easy-to-use model is presented for the prediction of the energy requirements at different scales. The mathematical model includes the definition of a specific energy parameter for each mobilized metal, obtained from the relationship between the amount of metal mobilized and the maximum that can be mobilized. The results indicate that the specific energy requirements for the removal of each target contaminant can be predicted as the process is scaled-up.
