NEW POINT OF USE DISINFECTION METHOD

由水生微生物引起的传染病爆发是一个主要的 公共卫生问题。传染性病原体可以从许多 水源包括饮用水和娱乐用水， 高纯度的水，如果没有适当的维护。一个潜在 对抗水传播疾病的手段是通过更多的 使用点消毒系统的广泛实施。然而，在这方面， 许多现有的消毒方法作为使用点是不可行的 由于成本和工艺的限制。的工作的目的 本提案中描述的是开发一种小规模的使用点臭氧 臭氧发生器每小时可产生1克臭氧。臭氧很有吸引力 因为它是一种有效的生物杀灭剂， 反应副产物。然而，臭氧是困难和昂贵的， 在小范围内产生。我们建议开发一个鞋盒大小的 电化学臭氧发生器，强调其自成一体的性质 和创新的低成本辅助组件。新方法具有 提供重要的水处理能力的潜力， 经济不景气的社区、农村地区和高密度 邻域（例如，沿着美墨边境的社区）。医院 需要无污染的饮用水和超纯清洁水 也可以从这种治疗中受益。远的潜力- 实现公共卫生福利可以直接通过 这项技术的发展。 拟定商业应用： 这项技术的应用范围超出了水的进入点 治疗系统。该技术也可应用于污染清洁- 向上和流出物管理。

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.
