  • Polishing of BTEX And MTBE Service Station Closure Effort - Case Study

    Aservice station in Montgomery County, Pa underwent a hydro- geologic re-assessment in March 2002. The contaminants at the site included BTEX constituents; MTBE, a fuel oxygenate; Isopropyl-benzene; and Napthalene. These Contaminants of Concern (COC’s) were not degrading rapidly through natural attenuation and direct oxidation in the form of Fenton’s Reagent. ...

  • The Analysis of BTEX and MTBE Using Specially Modified Purge Traps

    The existence of underground storage tanks containing gasoline and other petroleum products has facilitated the need for routine testing to determine if there has been any leakage into surrounding soil and ground water. The analytical methods test for “BTEX”, which is an acronym for benzene, toluene, ethyl benzene, and xylene. In many instances, testing is not limited to these ...

  • Degradation of methyl tert-butyl ether (MTBE) in water by glow discharge plasma

    This study evaluated the ability of the glow discharge plasma (GDP) technique to degrade methyl tert-butyl ether (MTBE) in an aqueous solution. The results showed that a large amount of hydrogen peroxide and highly active •OH free radicals were produced during the treatment. Various experimental parameters including discharge current, initial MTBE concentration and initial pH played significant ...

  • MTBE degradation by hydrodynamic induced cavitation

    Hydrodynamic induced cavitation generates imploding cavitation bubbles which can lead to degradation or even mineralisation of water constituents without addition of any chemicals. This technology overcomes the problems of ultrasound irradiation by the local production of a cavitation cloud close to the sonotrodes. Hydrodynamic cavitation can be stabilised downstream of the nozzle depending on ...

  • MTBE cleanup in Dunedin, Florida

    Field data from an MTBE cleanup in Dunedin, Florida, revealed reductions of MTBE from 1,700 ppb to 250 ppb in just two weeks. Within about 4 months, MTBE levels were reduced to 31ppb. After 7 months, the MTBE levels were 0 ppb. Over the same 7-month period Benzene levels fell from 610 ppb to 0 ppb. Toluene levels dropped from 2,400 ppb to 1.5ppb, Xylene fell from 11,000 ppb to 20 ppb, and ...

  • Effective treatment of MtBE and breakdown products using C-Sparge and Perozone®

    Ozone oxidation systems like C-SpargeTM (microbubble ozone) and Perozone® (peroxide-coated ozone) are used for treatment of a variety of contaminants. From non-volatile to volatile compounds, from saturated to unsaturated compounds. The most common contaminants treated are chlorinated solvents, petroleum products and PAHs. Engineered microbubble systems with ozone (C-SpargeTM) or a combination of ...

  • Application of photocatalytic process for removal of methyl tert-butyl ether from highly contaminated water

    The addition of methyl tert-butyl ether (MTBE) to gasoline as an additive to replace tetraethyl lead has brought about a significant improvement in air quality (Zang and Farnood, 2005a). MTBE raises the oxygen content of gasoline thus helps reduce harmful agent of CO, NOx and ydrocarbon emissions from vehicle exhausts (Jacobs et al., 2001; Zang and Farnood, 2005b; Guillard et al., 2003). About 20 ...

  • Overfill Spill at a Commercial Gas Station Results in NFA

    Site Summary This service station was approximately 150 feet from Peapack Brook, a stocked trout stream. In 1993, a petroleum hydrocarbon overfill spill occurred contaminating surrounding contaminated soils and underlying groundwater. In an effort to protect the stream from migrating BTEX, TBA, and MTBE plumes, two downgradient ORC barriers were installed. Additionally, following the excavation ...

  • Biodegradability of Alternative Oxygenates as a Sole Carbon Source or in the Presence of BTEX

    ABSTRACTThe biodegradability of alkylate compounds in serum bottles was investigated as a sole carbon source or in the presence BTEX. The biomass was acclimated with 2,3-dimethyl pentane (2,3- DMP), 2,4-dimethyl pentane (2,4-DMP) and 2,2,4-trimethyl pentane (2,2,4-TMP) in porous potreactors. The alkylates (2,3-DMP, 2,4-DMP, and 2,2,4-TMP) were completely biodegraded in all the sets of ...

  • Removal of methyl tertiary butyl ether (mtbe) vapour from contaminated air streams using different bacterial cultures in biotrickling filters.

    Methyl tertiary butyl ether (MTBE) was firstly introduced in the Islamic Republic of Iran in the end of 2001 as gasoline octane enhancer. Ordinary, reformulated gasoline contains 11-15% (v/v) of MTBE. Because of its low production cost and excellent blending characteristics, its production has been grown exponentially in the world, reaching a value of over 33 million tons per year (Fortin and ...
