SBIR Phase I: Ultraviolet (UV) Water Treatment with Short Wavelength Surface Discharge Lamps

0109181 Schaefer这个小型企业创新研究(SBIR)第一阶段项目解决了对具有成本效益的水处理的需求。紫外线(UV)光处理水中的化学污染物是有吸引力的，因为污染物被破坏，而不是像吸附技术那样将污染物转移到不同的介质中。然而，紫外线的使用受到灯电源电费的限制。该项目使用了最新开发的表面放电(SD)紫外线灯，其紫外线效率是行业标准汞紫外线灯的三倍，这将降低电力成本。此外，SD灯的紫外光谱波长较短，既可以提高破坏率，又可以减少化学氧化剂添加剂的用量。项目目标是优化灯的运行，展示SD灯在处理国家关注的两种污染物阿特拉津和亚硝基二甲胺(NDMA)方面的优势，并确定商业可行性。第一阶段的成功将确立基于SD灯的水处理过程的可行性，并将在第二阶段形成原型系统，并在第三阶段实现商业化。该项目近期的商业应用将在包括地下水、工业和市政废水、饮用水和一般消毒在内的大型水处理市场

0109181SchaeferThis Small Business Innovation Research (SBIR) Phase I project addresses the need for cost effective water treatment. Ultraviolet (UV) light treatment for chemical contaminants in water is attractive because contaminants are destroyed, unlike adsorption techniques that transfer the contaminant to a different media. However, the use of UV is limited by electricity costs for lamp power. This project uses a newly developed Surface Discharge (SD) UV lamp with UV efficiency three times higher than the industry standard mercury UV lamp, which will reduce electricity costs. Furthermore, the shorter wavelength UV spectrum of the SD lamp can both increase destruction rate and reduce the amount of chemical oxidant additive. Project objectives are to optimize lamp operation, to demonstrate the advantages of the SD lamp to treat atrazine and nitrosodimethylamine (NDMA), two contaminants of national concern, and to establish commercial feasibility. A successful Phase I will establish the feasibility of a water treatment process based on the SD lamp, and will lead in Phase II to a prototype system and to commercialization in Phase III.The near term commercial applications of this project will be in the large water treatment market that includes groundwater, industrial and municipal wastewater, drinking water and general disinfection
