Low Cost Ozone Sanitization of Drinking Water

描述(由申请人提供)：在各种水处理过程中，人们对用臭氧取代氯有很大的兴趣。一些过程包括废水处理、饮用水净化和漂白操作。虽然氯被视为一种低成本的消毒剂，但氯也存在许多问题，包括使用和运输氯是危险的，消毒副产品(如三卤代甲烷)是致癌物质，氯的氧化剂不像臭氧那么强(氯不能摧毁病毒和隐孢子虫，但臭氧可以)。CMS将推出其新型的抗臭氧薄膜，使用一种新的工艺来显著降低氧化过程中供应臭氧的成本。该计划的目标是将系统氧气成本(臭氧成本的主要组成部分)降低至少20%。这个项目将重点放在饮用水处理上。我们认为，建议的技术应具有广泛的适用性，包括废水、饮用水、注射用水和工艺水应用。在第一阶段，我们将建造全氟膜组件和一个整体系统，以供应低成本的氧气和低成本的臭氧。在该系统建成后，我们将展示其对一些污染物(硝基苯、腐植酸和隐孢子虫)的性能。我们与许多行业组织建立了牢固的工作关系。这些关系应该会增强我们成功完成这一计划以及随后商业化的能力。

DESCRIPTION (provided by applicant): There is a significant interest in displacing chlorine with ozone in a variety of water treatment processes. Some processes include wastewater treatment, purification of drinking water and bleaching operations. While chlorine is seen as a low cost disinfectant, there are many problems with chlorine including it is hazardous to use and ship, by-products of disinfection (e.g. trihalomethanes) are carcinogens and chlorine is not as strong an oxidant as ozone (Chlorine does not destroy viruses and 'cryptosporidium', but ozone does). CMS will introduce its novel ozone resistant membranes using a novel process to significantly reduce the cost of supplying ozone for oxidation processes. Program objectives are to reduce the system oxygen cost (which is a major component of ozone costs) by at least 20%. This program will focus on drinking water treatment. We believe the technology as proposed should have broad applicability including wastewater, drinking water, water for injection, and process water applications. In Phase I we will build both perfluoromembrane modules and an overall system for supplying low cost oxygen and low cost ozone. After the system is built we will demonstrate its performance on a number of contaminants (nitrobenzene, humic acid, and 'cryptosporidium'). We have established strong working relationships with a number of industrial organizations. These relationships should enhance our ability to successfully complete this program as well as subsequent commercialization.
