Schafer Associates, Inc. (WJSA) demonstrated, tested and evaluated a new ultraviolet (UV) lamp integrated with an existing commercial technology employing UV catalyzed peroxide oxidation to destroy organics in groundwater at an Oak Ridge K-25 site. The existing commercial technology is the perox-pure[trademark] process of Peroxidation Systems Incorporated (PSI) that employs standard UV lamp technology to catalyze H[sub 2]O[sub 2] into OH radicals, which attack many organic molecules. In comparison to classical technologies for remediation of groundwater contaminated with organics, the perox-pure[trademark] process not only is cost effective but also reduces contaminants to harmless by-products instead of transferring the contaminants from one medium to another (such as in activated carbon or air stripping). Although the perox-pure[trademark] process is cost effective against many organics, it is not effective for some organic contaminants of interest to DOE such as TCA, which has the highest concentration of the organics at the K-25 test site. Contaminants such as TCA are treated more readily by direct photolysis using short wavelength UV light. WJSA has been developing a unique UV lamp which is very efficient in the short UV wavelength region. Consequently, combining this UV lamp with the perox-pure[trademark] process results in a means for treating essentially all organic contaminants. In the program reported here, the new UV lamp lifetime was improved and the lamp integrated into a PSI demonstration trailer. Even though this UV lamp operated at less than optimum power and UV efficiency, the destruction rate for the TCA was more than double that of the commercial unit. An optimized UV lamp may double again the destruction rate; i.e., a factor of four greater than the commercial system.

This book was released on 1995 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this task was to evaluate the technical-and cost effectiveness of advanced oxidation processes (AOP), specifically UV/Oxidation (UVIOX) in remediating groundwaters containing 2,4,6-trinitrotoluene (TNT) and other nitroaromatics by performing a pilot-scale demonstration. In addition to evaluating the effectiveness of UV/OX methods, USAEC wanted to identify the cost parameters associated with each of the commercially available processes for the treatment of explosives and assess the adequacy of bench-scale testing data for predicting full-scale equipment requirements. All four of the UV/OX processes evaluated achieved the treatment criteria for mT and mB on one or more days of the demonstration. There was considerable variation in the consistency with which the processes met these criteria, It was also concluded that, based on this demonstration, routine bench-scale testing is inadequate for providing sufficient data for accurate design, siting, and costing for full-scale UV/OX systems for remediating explosives-contaminated groundwater.

This book was released on 1990 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Allied-Signal Aerospace Company currently operates a production facility in Kansas City, Missouri, under contract with the US Department of Energy (DOE). Over the years the operation of the DOE Kansas City Plant has resulted in the contamination of groundwater with chlorinated hydrocarbons, including trichloroethene (TCE). One of the plumes of contaminated groundwater, the underground tank farm (UTF) plume, was selected for remediation with an advanced oxidation process (AOP) consisting of simultaneous treatment by ozone (O3), ultraviolet (UV) radiation, and hydrogen peroxide (H2O2). Since the use of AOPs is relatively new for the removal of organics from groundwater, information on design criteria, costs, performance, and operating experience is not well documented in the literature. Therefore, the Oak Ridge National Laboratory (ORNL) was requested to evaluate the treatment process. This report documents the work performed through FY 1989. The results of the initial year of the evaluations, FY 1988, have been published previously, and the evaluation will continue at least through FY 1990. This report first briefly describes the treatment plant and the mechanisms of the treatment process. Next, the methodology and the results from the evaluation are discussed. Finally, conclusions and recommendations are presented. 8 refs., 14 figs., 16 tabs.
