看ISPE的指南,可以用紫外去掉臭氧。
Example: Ozonated Storage and Distribution
An ambient storage and distribution system can be operated effectively with an ozonated storage and a periodically ozonated loop, for microbial control. Typical levels of 0.02ppm to 0.2ppm of continuous ozone protect the water from microbial contamination. Frequently, two methods of generating ozone are employed, electrolytic and corona discharge. The corona discharge method generates ozone from oxygen in the air, while electrolytic method uses the oxygen in the water. Ozone should be completely removed from high purity water prior to usage by using UV irradiation. Ozone monitors also should be included to verify that ozone has been eliminated prior to the points of use, to maintain consistent ozone levels, and to confirm loop sanitization. In addition, atmospheric ozone monitoring should be installed to address safety concerns (See Occupational Safety and Health Administration (OSHA) Standards(Reference 26, Appendix 1)). Additional atmospheric monitoring of oxygen or hydrogen should be evaluated dependent upon the technology and specific installation. Ozone should be periodically circulated through the distribution loop by de-energizing the UV light, as required for sanitization and controlling biofilm development.
Typically, the level of ozone concentration during sanitization is increased.
