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.

描述（由申请人提供）：在各种水处理工艺中，人们对用臭氧取代氯非常感兴趣。一些工艺包括废水处理、饮用水净化和漂白作业。虽然氯被认为是一种低成本的消毒剂，但氯存在许多问题，包括使用和运输危险，消毒的副产物（例如三卤甲烷）是致癌物质，氯不是像臭氧那样强的氧化剂（氯不能破坏病毒和“隐孢子虫”，但臭氧可以）。CMS将采用一种新工艺推出其新型耐臭氧膜，以显著降低氧化工艺中臭氧的供应成本。计划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%。该项目将重点关注饮用水处理。我们认为，所提出的技术应具有广泛的适用性，包括废水，饮用水，注射用水和工艺用水应用。在第一阶段，我们将建造全氟膜组件和一个整体系统，用于供应低成本氧气和低成本臭氧。系统建成后，我们将展示其对一些污染物（硝基苯，腐殖酸和“隐孢子虫”）的性能。我们与许多行业组织建立了良好的合作关系。这些关系应该提高我们成功完成该计划以及随后商业化的能力。
