Comparison of Integrated AOP Systems for BTEX Removal From Solution
Comparison of Integrated AOP Systems for BTEX Removal From Solution This paper investigates the removal of BTEX compounds (benzene, toluene, ethylbenzene and xylene) from water using different advanced oxidation processes (AOPs) used singly or in combination with one another. This research is an extension of our work performed under the Environmental Management Science Program (EMSP) which addressed treating chlorinated organic contaminated water using sonication, vapor stripping and combined sonication + vapor stripping. In our current study, various AOP processes were investigated for their ability to remove BTEX compounds from solution, including the following. ? Ultraviolet (UV) light alone ? UV light + hydrogen peroxide (H2O2) ? Sonication alone ? Air sparging alone ? Air sparging + sonication ? Air sparging + UV light ? Sonication + UV light ? Sonication + H2O2 ? Sonication + air sparging + UV light ? Sonication + air sparging + H2O2 ? Sonication + air sparging + H2O2 + UV light ? Sonication + air sparging with O3 ? Sonication + O3 + H2O2 ? Sonication + O3 + H2O2 + UV light
