Abstract : The Air Force frequently relies on air-stripping technologies to remove organic chemicals from groundwaters contaminated from fuel and solvent spills. Although air stripping is extremely efficient at removing contaminants from the groundwater, these contaminants are only transferred into the air and in several states, air pollution controls are also required. Activated carbon beds are one potential emissions control under study. The objective of this study was to determine the effects of contaminant concentration, humidity, and chemical competition on the sorption performance of activated carbons. Based on laboratory results, a preliminary cost comparison was made for heated and unheated carbon beds. Volatile organics of interest included benzene, ethyl benzene, toluene, xylenes. trichloroethylene and 1,1-dichloroethylene. Keywords: Water pollution control; Water pollution abatement; Air pollution.
