This Small Business Innovation Research Phase 1 research project will develop a low power germicidal flow cell with a reduced form factor for point of use (PoU) water disinfection. It will use ultraviolet light emitting diodes (UV LEDs) along with a novel and proprietary flow cell design. Current ultraviolet PoU water disinfection is accomplished using discharge lamps, which requires high voltage, ballasts, and a relatively large form factor. The use of UV LEDs instead of discharge lamps will allow the light sources to reside inside a smaller form factor, and to function at lower overall electrical power, without line voltage and ballasts. The proposed unit also will facilitate two distinct and complementary disinfection mechanisms. One involves the structure and material of the flow cell itself, which is designed to improve upon the conventional flow cell by maximizing the ultraviolet dose received by microorganisms in the water. The other involves a specific photochemical mechanism between a material constituent of flow cell and water, resulting in an independent chemical pathway to disinfection.The broader impacts of this project are low power PoU disinfection with a smaller form factor will allow more UV water disinfection units to be employed in more locations. As the cost of UV LEDs continues to decrease, the system will become increasingly commercially attractive to consumers. The low power aspect will make the system potentially useful for battery operated field applications where line voltage is not available.

该小型企业创新研究第一阶段研究项目将开发一种低功耗杀菌流通池，其外形尺寸更小，用于使用点 (PoU) 水消毒。它将使用紫外线发光二极管 (UV LED) 以及新颖且专有的流通池设计。目前的紫外线 PoU 水消毒是使用放电灯完成的，这需要高电压、镇流器和相对较大的外形尺寸。使用 UV LED 代替放电灯将使光源能够驻留在更小的外形尺寸内，并以更低的总电力运行，无需线路电压和镇流器。拟议的装置还将促进两种不同且互补的消毒机制。一是涉及流通池本身的结构和材料，其设计目的是通过最大化水中微生物接收的紫外线剂量来改进传统流通池。另一个涉及流通池的材料成分和水之间的特定光化学机制，从而形成独立的化学消毒途径。该项目更广泛的影响是具有较小外形尺寸的低功率 PoU 消毒，将允许在更多地点使用更多的紫外线水消毒装置。随着 UV LED 的成本不断降低，该系统对消费者的商业吸引力将越来越大。低功耗特性将使该系统对于无法获得线路电压的电池供电现场应用具有潜在的用途。
