Biodegradation of Jet Fuel-4 (JP-4) in Sequencing Batch Reactors
1992
Bumpus, John A.
Several bacterial consortia were evaluated for use in the development of a sequencing batch reactor (SBR) for bioremediation of water contaminated with Jet Fuel-4. (JP-4). All of the bacterial systems tested had some ability to degrade components of JP-4. However, because of its ability to degrade rapidly components of JP-4 and because of it rapid oxygen utilization rates, a bacterial consortium from a soil contaminated with gasoline was selected for further study and was used in the development of an SBR to treat contaminated water. The bench scale SBR developed had a three liter capacity and a 1.5 liter head space. The atmosphere in the head space was changed only during the fill and draw portion of the reactor cycle. At other times, the system was closed and the only oxygen available was that dissolved in the water being treated or in the atmosphere of the headspace. Calculations revealed and experimental data confirmed that this amount of oxygen was sufficient to support extensive bioremediation of water contaminated with JP-4. Results demonstrated that this SBR was consistently able to bioremediate water contaminated with JP-4.
