Reverse osmosis (RO) is the most widely used technology in water treatment and desalination technologies for potable water production. Since its invention, RO has undergone significant developments in terms of material science, process, system optimization, methods of membrane synthesis, and modifications. Among various materials used for the synthesis of an RO membrane, the polyamide thin-film composite (PA-TFC) is by far the most common, owing to its excellent water permeability high salt rejection, and stability. However, a tradeoff between membrane permeability and salt rejection and membrane fouling has been a major hindrance for the effective application of this membrane. Thus, a broad investigation has been carried out to address these problems, and among which co-solvent interfacial polymerization (CAIP) and the surface modification of substrates and active layers of RO membrane have been the most effective approaches for controlling and improving the surface properties of the PA-TFC membrane. In this review paper, the problems associated with the RO membrane processes and strategies has been discussed and addressed in detail. Furthermore, as the focus of this review, the major advancements in the strategies used for enhancement of RO membrane performance through CAIP, and surface modifications were scrutinized and summarized.

反渗透膜的制造和改性技术及未来趋势:综述。

反渗透(RO)是用于饮用水生产的水处理和脱盐技术中使用最广泛的技术。自发明以来,反渗透技术在材料科学,工艺,系统优化,膜合成方法和改性方面取得了重大进展。在用于合成RO膜的各种材料中,聚酰胺薄膜复合材料(PA-TFC)由于其优异的透水性,高耐盐性和稳定性而成为最常见的材料。然而,在膜渗透性和除盐和膜污染之间的折衷一直是该膜的有效应用的主要障碍。因此,已经进行了广泛的研究以解决这些问题,其中,共溶剂界面聚合(CAIP),RO膜的基体和活性层的表面改性是控制和改善PA-TFC膜表面性能的最有效方法。在这篇综述文章中,与反渗透膜工艺和策略相关的问题已被讨论和详细解决。此外,作为本综述的重点,对通过CAIP增强RO膜性能和表面改性所采用的策略的主要进展进行了详细的审查和总结。与反渗透膜工艺和策略有关的问题已被讨论和详细解决。此外,作为本综述的重点,对通过CAIP增强RO膜性能和表面改性所采用的策略的主要进展进行了审查和总结。与反渗透膜工艺和策略相关的问题已被讨论和详细解决。此外,作为本综述的重点,对通过CAIP增强RO膜性能和表面改性所采用的策略的主要进展进行了详细的审查和总结。
