Microwaves in soil remediation from VOCs. 2. Buildup of a dedicated device

This work presents the design of a microwave opened applicator useful to perform the Microwave Induced Steam Distillation (MISD) process for soil remediation treatments. The prototype has been also realized and used to irradiate a 40 x 30 cm area with a given electromagnetic field distribution. Experiments carried out by in situ operations on a soil contaminated with VOC's are reported. Finally, the experimental data collected are described by a mathematical model previously proposed.
