Book Description
Determines the feasibility of using a traytype air stripping technology to successfully remove volatile organic compounds such as benzene, toluene, and a range of hydrocarbons from groundwater. Discusses a system to destroy the contaminants by ultraviolet flashlamps once they are transferred into the air.

Book Description
A common strategy for hydraulic containment and mass removal at VOC contaminated sites is p̀ump and treat (P & T).̀ In P & T operations, contaminated ground water is pumped from wells, treated above ground, and discharged. Many P & T remediation systems at VOC sites rely on air stripping technology because VOCs are easily transferred to the vapor phase. In stacked-tray air strippers, contaminated water is aerated while it flows down through a series of trays. System operations at LLNL are strictly regulated by the California and federal Environmental Protection Agencies (Cal/EPA and EPA), the Bay Area Air Quality Management District (BAAQMD), the California Regional Water Quality Control Board (RWQCB) and the Department of Toxic Substances Control (DTSC). These agencies set discharge limits, require performance monitoring, and assess penalties for non-compliance. National laboratories are also subject to scrutiny by the public and other government agencies. This extensive oversight makes it necessary to accurately predict field treatment performance at new extraction locations to ensure compliance with all requirements prior to facility activation. This paper presents treatability test results for a stacked- tray air stripper conducted at LLNL and compares them to the vendors̀ modeling software results.

Book Description
Environmental Science and Engineering, Inc. (ESE) performed a series of test runs in a packed column air stripper to determine performance for removal of four volatile contaminants. Test results were used to determine effect of various conditions such as matrix, contaminant concentration, stripper configuration, and temperature on stripper performance for treating ground water at various Department of the Army installations.

Book Description
Air stripping is an economical and efficient method of removing dissolved volatile organic compounds (VOCs) from contaminated groundwater. Air strippers, however, produce a vent air stream, which must meet the local air quality limits. If the VOC content exceeds the limits, direct discharge is not possible; therefore, a carbon adsorption VOC capture system is used to treat the vent air. This treatment step adds a cost of at least $50/lb of VOC captured. In this program, a combined air stripper/membrane vapor separation system was constructed and demonstrated in the laboratory. The membrane system captures VOCs from the stripper vent stream at a projected cost of $15/lb VOC for a water VOC content of 5 ppmw, and $75/lb VOC for a water VOC content of 1 ppmw. The VOCs are recovered as a small, concentrated liquid fraction for disposal or solvent recycling. The concept has been demonstrated in experiments with a system capable of handling up to 150,000 gpd of water. The existing demonstration system is available for field tests at a DOE facility or remediation site. Replacement of the current short air stripping tower (effective height 3 m) with a taller tower is recommended to improve VOC removal.
