Description:
The AWD technology simultaneously treats groundwater and soil-gas contaminated with volatile or ganic compounds (VOC), such as trichloroethylene (TCE) and tetrachloroethylene (PCE). This technology integrates two processes: (1) AquaDetox®, a moderate vacuum (pressure about 50 mm Hg or greater) stream stripping tower that treats contaminated groundwater, and (2) a soil vapor extraction (SVE) system that removes contaminated soil-gas for subsequent treatment with granular activated carbon (GAG) beds. The two technologies are integrated into a closed-loop system, providing simultaneous remediation of contaminated groundwater and soil-gas with no air emissions.
