DETERMINATION OF C-T VALUES IN OZONE DISINFECTION

这个小型企业创新研究第一阶段项目涉及设计和开发一种新的、直接确定消毒过程中臭氧接触时间的方法。使用彩色试纸监测接触时间(臭氧浓度与消毒时间的乘积)，提供简单、实时、大范围的消毒程度测量。该方法包括将臭氧活性染料浸渍在臭氧稳定的聚合物基质中，该聚合物基质可以被引入消毒环境中，在那里它将被缓慢漂白。拟议的第一阶段工作将用于设计一种成本效益高的方法来确定臭氧消毒过程中的接触时间。这种色带的好处是：(I)实时测量臭氧接触时间，(Ii)通过颜色变化简单确定，以及(Iii)广泛的工作范围。简而言之，在第一阶段将开展研究，以调查聚合物基材中包含的染料的臭氧漂白的关键问题，并将漂白程度与臭氧接触时间联系起来。 建议的商业应用：不可用

This small business innovation research Phase I project is concerned with the design and development of a new, direct method for determination of ozone contact time in disinfection processes. A color test strip will be used to monitor the contact time (product of ozone concentration and disinfection time), giving a simple, real-time, and broad range measurement of the degree of disinfection. The method involves impregnation of an ozone-reactive dye in an ozone-stable polymeric substrate that can be introduced into a disinfection environment where it will be slowly bleached. The proposed Phase I effort will be utilized to design a cost-effective method for determination of contact time in ozone disinfection processes. The benefits of this color strip are: (i) real-time measurement of ozone contact time, (ii) simple determination by color change, and (iii) broad working range. Briefly, in Phase I research will be carried out to investigate critical issues of ozone bleaching of dyes incorporated in a polymeric substrate and to relate the degree of bleaching to ozone contact time.
