Nanofibrous membranes for membrane distillation (MD) have demonstrated promising results in treating various water and wastewater streams. Significant progress has been made in recent decades because of the development of sophisticated membrane materials, such as superhydrophobic, omniphobic and Janus membranes. However, fouling and wetting remain crucial issues for long-term operation. This mini-review summarizes ideas as well as their limitations in understanding the fouling in membrane distillation, comprising organic, inorganic and biofouling. This review also provides progress in developing antifouling nanofibrous membranes for membrane distillation and ongoing modifications on nanofiber membranes for improved membrane distillation performance. Lastly, challenges and future ways to develop antifouling nanofiber membranes for MD application have been systematically elaborated. The present mini-review will interest scientists and engineers searching for the progress in MD development and its solutions to the MD fouling issues.
用于膜蒸馏(MD)的纳米纤维膜在处理各种水流和废水流方面已展现出令人期待的成果。近几十年来,由于超疏水、全憎水和Janus膜等先进膜材料的发展,取得了显著进展。然而,污垢和润湿仍然是长期运行的关键问题。本综述总结了在理解膜蒸馏中的污垢(包括有机污垢、无机污垢和生物污垢)方面的观点及其局限性。本综述还介绍了用于膜蒸馏的抗污垢纳米纤维膜的开发进展以及为提高膜蒸馏性能而对纳米纤维膜进行的持续改进。最后,系统阐述了开发用于MD应用的抗污垢纳米纤维膜所面临的挑战和未来方向。本综述将引起寻求MD发展进展及其MD污垢问题解决方案的科学家和工程师的兴趣。
