Reverse osmosis (RO) membrane technology is well-established in desalination. Aromatic polyamide (PA) thin-film composite (TFC) membrane dominates the commercial RO membrane market due to its high-salt rejection, water flux, and excellent chemical, thermal, and mechanical stabilization. However, membrane fouling is a common problem that has seriously hindered the wide application of RO membrane technology. This paper reviewed the PA RO membrane fouling types, and membrane fouling factors. Antifouling measures for RO membranes were summarized, including pretreatment, periodic cleaning, and modification of the support layer and PA layer. The future development of antifouling RO membranes was clarified.
反渗透（RO）膜技术在海水淡化领域已得到广泛应用。芳香族聚酰胺（PA）复合纳滤（TFC）膜因其高脱盐率、水通量以及出色的化学、热和机械稳定性，在商业RO膜市场占据主导地位。然而，膜污染是一个普遍存在的问题，严重阻碍了RO膜技术的广泛应用。本文综述了PA RO膜的污染类型和膜污染因素。总结了RO膜的防污措施，包括预处理、定期清洗以及对支撑层和PA层的改性。阐明了防污RO膜的未来发展方向。
