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.

说明(申请人提供)：安全饮用水的可获得性是一个重大的健康问题。水媒疾病仍然是世界范围内对人类健康的最大威胁之一，不仅造成人类痛苦，而且造成重大经济损失。臭氧(三原子氧)是一种强有力的氧化剂，作为消毒剂具有许多特性，包括能够灭活广泛的水传播病原体。虽然臭氧是使用点水处理的理想选择，但用传统方法很难小规模地产生臭氧，限制了臭氧在相对较大规模的水处理设施中的使用。这项第一阶段的研究证明了一种用于臭氧产生的新型微型电化学装置的可行性。这种微型设备由电池供电，携带方便，可以非常低的成本(10美元)制造。这种方法非常适合小规模使用。在喝水之前，可以使用该设备对水进行个人消毒，方法是将该设备部分浸入饮用水容器中，并允许其运行几分钟。在第一阶段，通过展示一种可批量生产的、紧凑的、自给自足的电化学发生器，实现了这项技术的潜力。第二阶段的目标是执行制造前任务，为将设备过渡到制造环境提供基础。长期目标是利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已经组建了一支由学术、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。
