Advances in electrokinetic soil remediation
- Louisiana State Univ., Baton Rouge, LA (United States)
Electrokinetic soil remediation, or electroreclamation, refers to a class of emerging techniques that use electricity to achieve decontamination, or chemical modification, of polluted soils or slurries. The EPA general classification, that they are in situ phase separation techniques is somewhat restrictive since the number and types of these methodologies are growing, for example, to include micellar electrokinetic soil decontamination and electrokinetic bioremediation. Following a discussion of the classical theory of electroosmosis, an overview will be given of the principles and current status of electrokinetic soil remediation for toxic metals extraction with illustrative bench, pilot, and field results. Emerging techniques, such as micellar electroremediation and electrokinetic bioremediation will also be reviewed and illustrated. The problems that can occur in a natural site will be shown and the economics of these methodologies, compared to alternative and competitive processes, will be estimated.
