ULTRAVIOLET PHOTOOXIDATION FOR THE DESTRUCTION OF VOCS IN AIR

Article abstract of DOI:10.1016/0043-1354(94)90057-4

Air stripping is an effective and economical process for removing volatile organic chemicals (VOCs) from contaminated water sources. However the air stripping process simply transfers the contaminants from the water to the air phase where they may continue to pose an environmental problem. In this study, the use of ultraviolet light (u.v.) photooxidation for treating the off gas from air stripping is examined. Subsequent papers will address linking u.v. photooxidation with air stripping in a closed loop stripping process. Fundamental studies are conducted to characterize the kinetics of the gas phase photooxidation of five volatile chlorinated alkanes and alkenes under different operating conditions. - Keywords: u.v.; volatile organic compounds; photooxidation; kinetics; gas phase; water treatment
