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

*** 9760405 Schaefer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电灯电力成本的限制。该项目使用的新型紫外线灯的效率是行业标准的三倍。此外，初步研究表明，新灯的短波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数量。该项目的目标是设计一种具有实际使用寿命的新型灯，并利用这种新型灯的短波长光谱来研究水处理过程，同时最大限度地减少氧化剂的数量。项目团队包括一家灯具制造商，以支持灯具工程，以及一家紫外线水处理公司，以支持受控有机破坏测试。研究结果将有助于确定基于新灯的水处理工艺的可行性，并打算在第二阶段改进灯和水处理工艺，制作原型，在第三阶段进行实地示范和商业化。一个成功的项目将导致紫外线灯的商业化和一种新的基于紫外线的水处理工艺，将取代现有的商业紫外线地下水系统。一个新的系统将在处理粉色、灰色、舱底和其他高浓度有机水污染问题方面具有成本效益。对于已经存在商业紫外线系统的地下水应用，水处理成本将大幅降低。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. ***
