Researchers developed and tested microwave heating pilot units for three soil remediation applications: in a kiln, in contaminated surface soil, and in contaminated subsurface soil. The pilots included an efficient off-gas treatment system. The pilot tests were performed using 6kW 2.45 GHz industrial microwave generators to treat materials from several contaminated sites. During the study, detailed spatial temperature and contaminants mass distribution were measured in the tested material. Pilot results confirmed promising data from earlier lab tests; high efficiencies of different contaminant removals were achieved at mild temperatures and with low energy consumption. The empirical knowledge gained allowed the determination of practical limitations for further scale-up and field application or for validation of future numerical models.
