Membrane filtration methods are prone to significant fouling, which lowers the efficiency of the operation. Hybrid techniques combining ozone and membrane filtration are promising for removing dissolved contaminants and reducing membrane fouling. However, a detailed knowledge of fouling processes is necessary to incorporate these technologies in large-scale water and wastewater treatment plants. Although fouling models for conventional membrane filtration systems are well established in the literature, modeling data for hybrid systems (combining membrane/advanced oxidative processes) with antifouling features are scarce. Therefore, a ceramic α-Al₂O₃/ZrO₂ commercial membrane with a molecular weight cut off of 10 kDa was functionalized applying layer-by-layer deposition of CuO for application in a hybrid system (membrane/catalytic ozonation) to treat contaminated surface water. The findings show that CuO-membranes can mitigate membrane fouling during hybrid processes, enhancing total filtration efficiency in the treatment of surface water. A fitting model that incorporated Hermia’s law as well as surface and bulk reactions that contribute to fouling removal is proposed and was successfully applied. The model allowed parameters to be estimated for the coated and uncoated membranes in the presence or absence of ozone. Membrane reusability was also investigated.

膜过滤方法容易产生明显的污垢，从而降低操作效率。臭氧和膜过滤相结合的混合技术有望去除溶解的污染物并减少膜污染。但是，要在大型水和废水处理厂中采用这些技术，需要详细了解结垢过程。尽管传统膜过滤系统的污垢模型在文献中已经很好地建立，但具有防污特性的混合系统（结合膜/高级氧化过程）的建模数据很少。因此，截留分子量为 10的陶瓷 α-Al ₂ O ₃ /ZrO ₂商用膜 kDa 被功能化，应用 CuO 的逐层沉积，用于混合系统（膜/催化臭氧化）以处理受污染的地表水。研究结果表明，CuO 膜可以减轻混合过程中的膜污染，提高地表水处理的总过滤效率。提出并成功应用了一种拟合模型，该模型结合了 Hermia 定律以及有助于去除污垢的表面和本体反应。该模型允许在存在或不存在臭氧的情况下估计涂层和未涂层​​膜的参数。还研究了膜的可重复使用性。
