SBIR Phase I: Treatment of Organically Contaminated Water with Short Wavelength Ultraviolet Light

* 9760405舍费尔 这个小型企业创新研究第一阶段项目解决了对具有成本效益的水处理系统的需求。 紫外线（UV）水处理是有吸引力的，因为污染物被破坏，不像过滤技术，产生有毒的副产品。 紫外线水处理系统的使用受到灯功率的电力成本的限制。 该项目使用了一种新的紫外线灯，其效率比行业标准高出三倍。 此外，初步研究表明，新灯的较短波长紫外光谱既增加了氧化速率，又减少了许多有机分子的氧化剂量。 该项目的目标是设计一种具有实用寿命的新灯，并使用它来研究水处理过程，使用新灯的短波长光谱，同时最大限度地减少氧化剂的量。 该项目小组包括一个灯制造商，以支持灯工程和紫外线水处理公司，以支持控制有机销毁测试。 研究结果将用于建立基于新灯的水处理工艺的可行性，并旨在在第二阶段导致灯和水处理工艺的改进，原型，现场演示和第三阶段的商业化。 一个成功的项目将导致紫外线灯的商业化和一个新的紫外线水处理过程，将取代现有的商业紫外线地下水系统。 一个新的系统将是成本效益的清理粉红色，灰色，舱底和其他高浓度有机水污染的问题。 对于已经存在商业紫外线系统的地下水应用，水处理成本将大幅下降。 此外，新系统具有替代氯化的潜力。 ***

*** 9760405 Schaefer This Small Business Innovation Research Phase I project addresses the need for cost effective water treatment systems. Ultraviolet (UV) water treatment is attractive because contaminants are destroyed, unlike filtration techniques that produce toxic byproducts. The use of UV water treatment systems is limited by electricity cost for lamp power. This project uses a new UV lamp with three times higher efficiency than the industry standard. Furthermore, initial research indicates that the shorter wavelength UV spectrum of the new lamp both increases oxidation rates and reduces the amount of oxidant for many organic molecules. The project objectives are to engineer a new lamp with practical lifetime and use it to research the water treatment process using the new lamp's short wavelength spectrum while minimizing the quantity of oxidant. The project team includes a lamp manufacturer to support lamp engineering and a UV water treatment company to support controlled organic destruction testing. The results will serve to establish the feasibility of a water treatment process based on the new lamp, and are intended to lead in Phase II to refinement of the lamp and water treatment process, a prototype, field demonstrations and commercialization in Phase III. A successful project will result in the commercialization of UV lamps and a new UV based water treatment process that will supersede existing commercial UV groundwater systems. A new system would be cost effective for cleaning up pink, gray, bilge and other high concentration organic water contamination problems. For groundwater applications where commercial UV systems already exist, water treatment costs will decrease by large increments. Furthermore, the new system has potential as a replacement for chlorination. ***
