SBIR Phase I: Delivery of Hyper-Concentrated Dissolved Ozone for More Effective Treatment of Drinking Water

该小型企业创新研究第一阶段项目旨在测试中试规模的超浓缩溶解臭氧（HYDOZTM）喷射器系统的有效性，效率和安全性，用于市政饮用水处理厂预防和去除消毒副产物（DBP），去除藻类（MIB和土臭素）的异味，以及消毒细菌。这项正在申请专利的技术是一种新的方法，可以更有效，可控和安全地将臭氧从气相转移到高浓度的液体溶液中。HYDOZ处理将与氯化进行比较，并将在试验工厂内的两个位置进行：试验工厂的流入口结构和处理后氯化之前的流出口。HYDOZ技术将为饮用水处理设施提供一种经济的替代方案，以降低2006年1月颁布的第二阶段DBP规则所要求的消毒副产物（DBP）浓度，同时实现改善病原体处理和减少饮用水异味的好处。臭氧在饮用水处理设施中的广泛使用将提高美国和国外饮用水的安全性和质量。

This Small Business Innovation Research Phase I project proposes to test the effectiveness, efficiency and safety of a pilot-scale Hyper-concentrated Dissolved Ozone (HYDOZTM) Injector system for use within municipal drinking water treatment plants for prevention and removal of disinfection byproducts (DBP), removal of off-flavors from algae (MIB and geosmin), and disinfection of bacteria.. This patent-pending technology is a novel method for more efficient, controllable and safe transfer of ozone from gas phase to liquid solution at high concentrations. HYDOZ treatment will be compared to chlorination and will occur at two locations within the pilot-plant: at the flow inlet structure of the pilot plant and at the flow outlet prior to post-treatment chlorination. HYDOZ technology will provide drinking water treatment facilities with an economic alternative to reduce the concentration of disinfection byproducts (DBPs) as mandated by the Stage II DBP rules that were enacted in January 2006 while simultaneously realizing benefits of improved treatment of pathogens and reduction of off-flavors in drinking water. The expanded use of ozone in drinking water treatment facilities will improve the safety and quality of drinking water in the U.S. and abroad.
