DESCRIPTION (provided by applicant): The availability of safe drinking water is a significant health concern. Waterborne diseases remain one of the most significant threats to human health worldwide, resulting not only in human suffering, but in significant economic loss as well. Ozone (triatomic oxygen) is a potent oxidant with many attributes as a disinfectant including the ability to inactivate a broad spectrum of waterborne pathogens. Although ideal for Point of Use water treatment, ozone has been difficult to generate on a small scale with conventional methods, restricting the use of ozone to relatively large scale water treatment installations. This Phase I study has demonstrated the feasibility of a new miniature electrochemical device for ozone generation. The miniature device is battery operated, portable, and can be manufactured at very low cost (<$10). The method is ideal for small-scale uses. It is possible to use the device to personally disinfect water immediately before water is consumed, by partial immersion of the device in the drinking vessel and allowing it to operate for a few minutes. In Phase I, the potential of this technology was realized by demonstrating a mass producible, compact, self-contained electrochemical generator. The goal of Phase II is to carry out pre-manufacturing tasks, providing a foundation for transitioning the device to the manufacturing environment. The long-term aim is to use technical information from the Phase II research as the basis for commercialization for a variety of pertinent Point of Use markets. Lynntech has assembled a highly skilled team of academic, manufacturing, and sales partners to successfully commercialize the proposed technology.

描述（由申请人提供）：安全饮用水的可用性是一个重大的健康问题。水媒疾病仍然是全世界人类健康面临的最严重威胁之一，不仅给人类带来痛苦，而且造成重大经济损失。臭氧（三原子氧）是一种有效的氧化剂，作为消毒剂具有许多属性，包括杀灭广谱水性病原体的能力。尽管臭氧对于使用点水处理是理想的，但是难以用常规方法在小规模上产生臭氧，从而将臭氧的使用限制在相对大规模的水处理装置中。第一阶段的研究已经证明了一种新的微型电化学装置产生臭氧的可行性。微型设备是电池供电的，便携式的，并且可以以非常低的成本（<10美元）制造。该方法非常适合小规模使用。通过将该装置部分浸入饮用容器中并允许其操作几分钟，可以在饮用水之前立即使用该装置对水进行个人消毒。在第一阶段，该技术的潜力是通过展示一个大规模生产，紧凑，独立的电化学发电机实现的。阶段II的目标是执行制造前任务，为将器械过渡到制造环境提供基础。长期目标是使用第二阶段研究的技术信息作为各种相关使用点市场商业化的基础。Lynntech组建了一支由学术、制造和销售合作伙伴组成的高技能团队，成功地将拟议的技术商业化。
