This review considers the forward osmosis (FO) membrane process as one of the feasible solutions for water desalination. Different aspects related to the FO process are reviewed with an emphasis on ultrasound assisted FO membrane processes. The different types of membranes used in FO are also reviewed and discussed; thus, their configuration, structure and applications are considered. Coupling ultrasound with FO enhances water flux through the membrane under certain conditions. In addition, this review addresses questions related to implementation of an ultrasound/FO system for seawater desalination, such as the impact on fouling, flow configuration, and location of fouling. Finally, the mechanisms for the impact of ultrasound on FO membranes are discussed and future research directions are suggested.
本综述将正向渗透(FO)膜工艺视为海水淡化的可行解决方案之一。对与正向渗透工艺相关的不同方面进行了综述,重点是超声辅助正向渗透膜工艺。还对正向渗透中使用的不同类型的膜进行了综述和讨论;因此,考虑了它们的构型、结构和应用。在某些条件下,将超声与正向渗透相结合可提高水透过膜的通量。此外,本综述还探讨了与实施超声/正向渗透海水淡化系统相关的问题,如对污垢的影响、流动构型和污垢位置。最后,讨论了超声对正向渗透膜影响的机制,并提出了未来的研究方向。
