Membrane technologies have broad applications in the removal of contaminants from drinking water and wastewater. In recent decades, ceramic membrane has made rapid progress in industrial/municipal wastewater treatment and drinking water treatment owing to their advantageous properties over conventional polymeric membrane. The beneficial characteristics of ceramic membranes include fouling resistance, high permeability, good recoverability, chemical stability, and long life time, which have found applications with the recent innovations in both fabrication methods and nanotechnology. Therefore, ceramic membranes hold great promise for potential applications in water treatment. This paper mainly reviews the progress in the research and development of ceramic membranes, with key focus on porous ceramic membranes and nanomaterial-functionalized ceramic membranes for nanofiltration or catalysis. The current state of the available ceramic membranes in industry and academia, and their potential advantages, limitations and applications are reviewed. The last section of the review focuses on ceramic membrane fouling and the efforts towards ceramic membrane fouling mitigation. The advances in ceramic membrane technologies have rarely been widely reviewed before, therefore, this review could be served as a guide for the new entrants to the field, as well to the established researchers.
膜技术在饮用水和废水的污染物去除方面有广泛的应用。在过去几十年中，陶瓷膜在工业/市政废水处理和饮用水处理方面取得了快速的进展，因为它们具有优于传统聚合物膜的优势。陶瓷膜的有益特性包括抗污染、高渗透性、良好的可恢复性、化学稳定性和长寿命，这些特性在制造方法和纳米技术的创新方面得到了应用。因此，陶瓷膜在水处理方面具有很大的应用潜力。本文主要综述了陶瓷膜的研究和开发进展，重点介绍了用于纳滤或催化的多孔陶瓷膜和纳米材料功能化陶瓷膜。综述了工业和学术界中现有的陶瓷膜的现状、潜在的优势、局限性和应用。综述的最后一部分重点介绍了陶瓷膜污染和减轻陶瓷膜污染的努力。陶瓷膜技术的进展以前很少被广泛综述，因此，这篇综述可以为该领域的新进入者以及资深研究人员提供指导。
