Antenna-based rf heating technology for soil remediation

摘要

Results from two sites, Ft. Wainwright, Alaska and an active retail petroleum facility in the Midwest demonstrate two applications of radio frequency (RF) antenna heating for safely accelerating site closures. At Ft. Wainwright located in a cold climate, preliminary results suggest that RF enhanced bioremediation during one year of an ogoing pilot test. The combination of RF with soil vapor extraction (SVE) at a Midwest United States retail petroleum facility and convenience store resulted in a six-month instead of a two to three year cleanup using only SVE.
