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，直接的方法，用于确定消毒过程中臭氧接触时间。将使用颜色测试条来监测接触时间（臭氧浓度和消毒时间的乘积），从而对消毒程度进行简单、实时和宽范围的测量。该方法包括将臭氧反应性染料浸渍在臭氧稳定的聚合物基材中，该基材可以被引入消毒环境中，在该环境中它将被缓慢漂白。拟议的第一阶段工作将用于设计一种具有成本效益的方法，用于确定臭氧消毒过程中的接触时间。该颜色条的优点是：（i）实时测量臭氧接触时间，（ii）通过颜色变化进行简单测定，以及（iii）工作范围宽。简而言之，在第一阶段的研究将进行调查的关键问题，臭氧漂白的染料纳入聚合物基板，并与臭氧接触时间的漂白程度。 拟议商业应用：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.
