Abstract
The opportunity of this proposal is to develop a new ¿Sparker¿ process for treating organic hazardous contaminants in water and liquid waste, including persistent and bioaccumulative and toxic chemical (PBT¿s), and polycyclic aromatic hydrocarbons (PAH¿s). Sparker technology also has potential for in-situ treatment of dense non-aqueous phase liquids (DNAPL¿s) and sludge. Sparkers are pulsed electrical discharges between electrodes in water the generate UV light, OH radicals, a strong pressure gradient and a sonicating bubble, that offer a possible multi-mode process for treating water. The multi-mode process may provide effective for treating dark water and sludge. Sparkers, as a potential replacement for UV lamps, are free of mercury, robust and potentially lower in cost. Because sparkers are immersed directly in the water, they have no fragile envelope that needs to be cleaned. This Phase I will use an innovative, patented sparker with intense UV emission, which has been used to treat water contaminated with the herbicide atrazine (ATZ) and industrial contaminated n-nitrosodimethylamine (NDMA). The sparker reduced contaminants with higher destruction rates and consumed less electricity than UV lamps. This preliminary demonstration is the basis of the proposed research aimed at developing a commercial sparker process for use in hazardous waste management. The overall objective of this Phase I is to demonstrate the feasibility of treating a range of PBT¿s and PAH¿s through the treatment of a benzo(a)pyrene, from the EPA¿s PBT list and fluorine, a PAH on the EPA Priority Pollutants List. Phase I also will test for the generation of breakdown byproducts, evaluate sparker operation in dark water and sludge, and address potential for in-situ water treatment. A successful Phase I will lead to a Phase II to conduct further research and develop the sparker process into a prototype for subsequent commercialization. Internationally known water treatment research and the largest UV water treatment company in North America re collaborators on this project.
