ABSTRACT

Dentists wish to prepare enough volume to meet the dental office ozonated water consumption and to reach the desired concentration in the least amount of ozonation time. Several factors affect ozone gas mass transfer in water and the corresponding ozonated water concentration can be measured with analytical or direct in-line monitoring methods. An alternative, ozone gas solubility ratio (SR) may be used as a reference to predict ozonated water concentration. SR of 0.25 is often cited in the literature, but it can vary between 0.2 and 0.4 according to different ozonation configurations and parameters. A total of 70 tests were performed using different ozonation configurations which are commonly used in dental practice. Ozone concentration in water was measured and the SR was calculated. SR varied between 0.13 and 0.4. To our knowledge, this study has never been carried out before and aims to propose practical guidelines on selecting the optimum water ozonation configurations in dental practice, as well as to calculate their corresponding dissolved ozone concentration.

摘要

牙医希望准备足够的体积来满足牙科诊所臭氧化水的消耗量，并在最少的臭氧化时间内达到所需的浓度。有几个因素会影响水中的臭氧气体传质，相应的臭氧水浓度可以通过分析或直接在线监测方法进行测量。另一种方法是臭氧气体溶解度比 (SR) 可用作预测臭氧水浓度的参考。文献中经常引用 0.25 的 SR，但根据不同的臭氧化配置和参数，它可以在 0.2 和 0.4 之间变化。使用牙科实践中常用的不同臭氧配置进行了总共 70 次测试。测量水中的臭氧浓度并计算 SR。SR 在 0.13 和 0.4 之间变化。据我们所知，
