Effect of BTEX and Ethanol on Biodegradation of MTBE
Methyl-tert-butyl (MTBE) is widely used in gasoline to reduce ozone and carbon monoxide emissions. However, it is highly water-soluble and does not absorb well to sediments, making it move quickly through groundwater systems. In addition, MTBE resists biological degradation, compared to other gasoline components, probably because of the high energy required to cleave its ether bond. The contami...
متن کاملAnaerobic Biodegradation of MTBE at a Gasoline Spill Site
To manage risk or to implement natural attenuation as a remedy, regulatory agencies must understand the processes that attenuate methyl-tert-butyl ether (MTBE) in ground water. Most case studies and laboratory studies in the literature indicate that natural biodegradation is not important; however, recent reports indicate that natural biodegradation of MTBE plays an important role under certain...
متن کاملRole of back diffusion and biodegradation reactions in sustaining an MTBE/TBA plume in alluvial media.
A methyl tert-butyl ether (MTBE) / tert-butyl alcohol (TBA) plume originating from a gasoline spill in late 1994 at Vandenberg Air Force Base (VAFB) persisted for over 15 years within 200 feet of the original spill source. The plume persisted until 2010 despite excavation of the tanks and piping within months after the spill and excavations of additional contaminated sediments from the source a...
متن کاملModel description and kinetic parameter analysis of MTBE biodegradation in a packed bed reactor.
A dynamic modeling approach was used to estimate in-situ model parameters, which describe the degradation of methyl tert-butyl ether (MTBE) in a laboratory packed bed reactor. The measured dynamic response of MTBE pulses injected at the reactor's inlet was analyzed by least squares and parameter response surface methodologies. Response surfaces were found to be statistically significant and thu...
متن کاملBiodegradation Kinetics of MTBE in Laboratory Batch and Continuous Flow Reactors
Methyl tert-butyl ether ~MTBE! biodegradation was investigated using a continuously stirred tank reactor with biomass retention ~porous pot reactor! operated under aerobic conditions. MTBE was fed to the reactor at an influent concentration of 150 mg/L ~1.70 mM!. An identical reactor was operated as a killed control under the same conditions. Operation of these reactors demonstrated that remova...
