Membrane contactor is a device generally used for the removal or the absorption of a gas into another fluid. The membrane acts as a barrier between the two phases and mass transfer occurs by diffusion and not by dispersion. This article is a review of the application of membrane contactor technology for ozonation applied to water treatment. The challenge of removing micropollutants is also discussed. In the first part, the ozonation process is mentioned, in particular chemical reactions induced by ozone and its advantages and disadvantages. In the second part, generalities on membrane contactor technology using hollow fibers are presented. Then, the benefit of using a membrane contactor for the elimination of micropollutants is shown through a critical analysis of the influence of several parameters on the ozonation efficiency. The impact of the membrane material is also highlighted. Finally, several modeling approaches are presented as a tool for a better understanding of the phenomena occurring in the contactor and a possible optimization of this process.
膜接触器通常用于将一种气体去除或吸收到另一种流体中。膜在两相之间起到屏障的作用，质量传递通过扩散而不是分散发生。本文综述了膜接触器技术在水处理中的臭氧应用。还讨论了去除微污染物的挑战。在第一部分中，提到了臭氧氧化过程，特别是臭氧诱导的化学反应及其优缺点。在第二部分，介绍了使用中空纤维的膜接触器技术的概况。然后，通过对几个参数对臭氧效率的影响进行批判性分析，表明了使用膜接触器消除微污染物的好处。还强调了膜材料的影响。最后，介绍了几种建模方法，作为更好地理解接触器中发生的现象并可能优化该过程的工具。
