Vacuum sparging process for treating contaminated groundwater and/or wastewater

摘要

A process for the removal of hydrocarbon contaminates from groundwater and/or wastewater in ground wells, treatment trenches or above-ground tanks which utilizes differential pressure between the area above the groundwater and/or wastewater and the purging gas introduced therein to the upward flow of bubbles of the purging gas through the groundwater and/or wastewater requiring stripping or volatilization to remove the hydrocarbon contaminates therefrom.
