Description:

A demonstration of the Zenon cross-flow pervaporation technology was conducted under the Superfund Innovative Technology Evaluation (SITE) program in February 1995 to determine the removal efficiency of trichloroethylene (TCE) from groundwaters at the Naval Air Station North Island, Coronado, California. Pervaporation is a membrane-based process that removes volatile organic compounds (VOCs) from aqueous matrices. It is suitable for reducing high concentrations, as a pretreatment step, but may require further VOC reduction by carbon adsorption to meet regulatory limits. Analytical results from the demonstration indicate that the Zenon technology, when operating at optimum conditions, effectively removed an average of 97.3 percent of the TCE from the groundwaters (from overall average of 140 mg/L to about 1.4 mg/L).
