NEW POINT OF USE DISINFECTION METHOD

由水媒微生物引起的传染病的暴发是主要的 公共卫生问题。感染性病原体可以从许多地方传播 水源包括饮用水和娱乐用水，甚至可能发生 如果没有得到适当的维护，在高度净化的水源中。一种潜力 抗击水传播疾病的手段是通过更多的 广泛实施使用点消毒系统。然而， 许多现有的消毒方法作为使用点并不可行 治疗由于成本和工艺的限制。这项工作的目的是 这项提案中描述的是开发一种小规模的使用点臭氧 每小时能产生一克臭氧的发电机。臭氧很吸引人 因为它是一种有效的杀生剂，产生的有害物质相对较少 副产物反应。然而，臭氧是困难和昂贵的 小规模地生产。我们建议开发一种“鞋盒”大小 电化学臭氧发生器，强调其自给自足的性质 和创新的低成本辅助部件。新方法具有 有潜力为小型、 经济不景气的社区、农村地区和高密度 社区(例如，美国和墨西哥边境的社区)。医院 需要无污染饮用水和超纯净水 也可以从这种治疗中受益。远方的潜力-- 实现公共卫生福利可以通过 这项技术的发展。 建议的商业应用： 这项拟议的技术的应用范围超出了入口点水域。 治疗系统。该技术还可以应用于污染清理- UP和流出物管理。

Outbreaks of infectious diseases caused by waterborne microbes is a major public health concern. Infectious agents can be transmitted from many sources including drinking water and recreational water and can occur even in highly purified water sources if not properly maintained. A potential means to combat the transmission of disease from water is through the more widespread implementation of point-of-use disinfection systems. However, many existing disinfection methods are not viable as point-of-use treatments because of cost and process limitations. The aim of the work described in this proposal is to develop a small scale point-of-use ozone generator able to produce one gram of ozone per hour. Ozone is attractive because it is a potent biocide that produces relatively few harmful reaction by products. However, ozone is difficult and expensive to generate on a small scale. We propose to develop a "shoe-box" sized electrochemical ozone generator, emphasizing the its self-contained nature and innovative low cost auxiliary components. The new method has the potential to provide an important water treatment capability to small, economically depressed communities, rural areas, and high density neighborhoods (e.g., communities along the US Mexican border). Hospitals requiring contaminant free drinking water and ultra pure cleaning water could also benefit from this type of treatment. The potential for far- reaching public health benefits can be directly advanced through the development of this technology. PROPOSED COMMERCIAL APPLICATION: The proposed technology has applications beyond point-of-entry water treatment systems. The technology can also be applied to pollution clean- up and effluent management.
