Bioremediation of water contaminated with jet fuel-4 in a modified sequencing batch reactor

Various in situ or pump and treat systems are used for the remediation and/or containment of groundwater. Tougher air pollution regulations have mandated the implementation of pump and treat strategies that minimize losses of organic compounds because of uncontrolled air stripping. A modified bench-...

Description
Summary:Various in situ or pump and treat systems are used for the remediation and/or containment of groundwater. Tougher air pollution regulations have mandated the implementation of pump and treat strategies that minimize losses of organic compounds because of uncontrolled air stripping. A modified bench-scale sequencing batch reactor (SBR) was intermittently closed to test its flexibility and applicability as a system for the treatment of Jet Fuel-4 (JP-4)-contaminated groundwater associated with free product recovery. The SBR was operated for 180 days on JP-4-contaminated water that contained high concentrations of monoaromatic hydrocarbons. Typically, the effluent contained less than 50 μg/L of total petroleum hydrocarbons with much lower levels for the benzene, toluene, ethyl benzene, and xylenes and met the discharge levels required by most state regulatory agencies.
