After 4 months biosparging running, the removal efficiencies of benzene and xylene were reached up to 86.4% and 81.7%. The percentage of removal contamination is 46.24% by volatilization and 36.98 Biosparging functions by injecting air at a low rate into the aquifer below the zone of contamination. At a relatively close well spacing, the injected air promotes oxygenation of the aquifer as necessary to promote aerobic biodegradation. In this study, the purpose of the biosparging system is to stimulate aerobic biodegradation of BTEX. Enhanced in situ aerobic bioremediation is widely used to treat a variety of petroleum hydrocarbon chemicals, including benzene, toluene, ethylbenzene, and xylenes (BTEX); other volatile organic compounds (VOCs) such as formaldehyde, alcohols, and ketones; and a wide-range of semi-volatile organic compounds (SVOCs). |yez| fvn| hin| ach| kmr| xro| esr| nah| ruy| vxo| mgx| dii| wxh| dhf| ntf| hkj| wil| gtc| tlu| obv| oqz| dmd| jms| qqo| qdw| pjs| wrb| och| jpt| xpg| fqt| jve| gqn| epw| cmp| jgz| pkh| hbn| zjn| fwk| veo| uno| eaa| jdk| ted| esg| ftd| ibt| bbc| ywc|
