Mobile Radio-frequency Platform for a Thermally Enhanced Soil Vapour Extraction

A new technological approach for direct heating of large volumes of contaminated soil using radio-frequency (RF) energy is described. The method can be used to thermally enhance a variety of remediation techniques such as biodegradation and soil vapour extraction. The technical basis, a container-based modular and mobile radio-frequency platform is presented and the benefits of this platform working under harsh field conditions are demonstrated. Additionally, aspects of electromagnetic compatibility, system reliability and safety are discussed.
