SBIR Phase II: Electrochemical Ozone Generator

这个小型企业创新研究（SBIR）第二阶段项目将开发一种基于电化学发生器的水消毒系统，该发生器直接将臭氧产生到工艺用水中。 由于其优良的消毒和氧化品质，臭氧被广泛用于饮用水和工艺水净化处理。 臭氧已被证明可以灭活耐药微生物，如隐孢子虫和贾第鞭毛虫，这些微生物通过饮用水和工艺用水在美国引起了大量流行病。 为了能够更广泛地采用臭氧作为消毒剂，需要改进臭氧发生器，使其比电晕电弧放电系统操作更安全，并且安装和操作更具成本效益。 在第一阶段技术和经济可行性论证的基础上，第二阶段项目将开发一种基于电化学的水消毒系统，用于商业部署。 第二阶段计划的重点是最终确定电催化剂配方，优化模块设计的性能和成本，将反应器模块纳入包装的最终用途产品，并使用战略合作伙伴评估现场应用中的水消毒过程。该项目的更广泛/商业影响是改进和降低成本的消毒系统，这将防止大规模爆发的污染水伤害公众。 这些事件推动了先进质量控制方法的迫切性，特别是在食品制造业。 随着臭氧发生系统的广泛采用，由于其作为杀菌剂对李斯特菌、沙门氏菌、大肠杆菌的有效性，水和食源性疾病都将减少。大肠杆菌，以及水果、蔬菜、肉类和海鲜中发现的任何其他病原体。通过改进的电化学反应器设计和催化剂开发，将实现对科学和技术领域的贡献，从而实现低成本和高能效的臭氧消毒系统。

This Small Business Innovation Research (SBIR) Phase II project will develop a water disinfection system based on an electrochemical generator that produces ozone directly into process water. Because of its excellent disinfection and oxidation qualities, ozone is widely used for drinking water and process water purification treatment. Ozone has been proven to deactivate resistant microorganisms such as Cryptosporidium Parvam and Giardia Lambia that have caused a large number of epidemics in the United States through drinking and process water. To enable wider adoption of ozone as an disinfectant, improvements in ozone generators are needed that are safer to operate than the corona arc discharge systems and that are more cost effective to install and operate. Building on demonstration of technical and economic feasibility during Phase I, this Phase II project will develop an electrochemistry based water disinfection system for commercial deployment. The Phase II program will focus on finalizing the electrocatalyst formulation, optimizing the module design for performance and cost, incorporating the reactor module into a packaged end-use product, and evaluating the process for disinfecting water in field applications using strategic partners. The broader/commercial impact of this project is an improved and lower cost disinfection system that will prevent the vast outbreaks of contaminated water that harm the general public. These occurrences push the utmost urgency for advanced quality control methods, especially in food manufacturing. With the wider adoption of ozone generation systems, both water and food-borne diseases would diminish due to its effectiveness as a disinfectant against Lysteria, Salmonella, E. coli, and any other pathogens found in fruits, vegetables, meats, and seafood. Contributions to the scientific and technological field will be realized by the improved electrochemical reactor design and catalyst development that enables an ozone disinfection system that is low in cost and energy efficient.
