The application of a rate expression for the reductive dehalogenation of TCE-contaminated groundwater to the design and performance of a funnel-and-gate system
- EPA, Athens, GA (United States)
Laboratory and pilot-scale experiments were performed to obtain data for the conversion of trichlorethene (TCE) in the presence of granular iron and iron/pyrite mixtures. A continuous flow system was used to treat artificial and natural groundwater over a range of flow rates. Axial concentration on profiles were determined for influent concentrations of up to 500 ppm TCE, An overall rate expression was developed from these results and the operating conditions associated with mass transfer control of the reaction identified. This rate expression was used to predict the performance of a prototype funnel and gate system. The influences of flow rate, residence time, and TCE concentration on the design of a funnel and gate system were considered in separate computer simulations.
