Abstract

Electro-driven separation processes offer several potential advantages over pressure-driven separation processes such as reverse osmosis for water reuse and desalination, including energy savings for low-salinity waters, cation or anion selectivity, and versatility for fit-for-purpose treatment. In this perspective, we review technologies for electro-driven separation processes and evaluate their prospect for marginalized water sources and fit-for-purpose water treatment, which include improving freshwater sustainability, protecting environmental flows, and improving recycling of industrial process streams and municipal wastewater reuse. We discuss critical aspects related to application, implementation, and techno-economic evaluation of electro-driven separation technologies. Electro-driven processes provide viable options to enhance a circular water economy by reducing salinity and selectively separating contaminants while recovering valuable products with increased environmental sustainability.

电力驱动海水淡化过程在可持续应用中的挑战和机遇

与压力驱动的分离过程相比，电驱动的分离过程具有几个潜在的优势，例如用于水回用和海水淡化的反渗透，包括低盐度水的节能，阳离子或阴离子的选择性，以及适合目的处理的多功能性。从这个角度来看，我们回顾了电驱动分离工艺的技术，并评估了它们在边缘水源和适合用途的水处理方面的前景，包括提高淡水可持续性，保护环境流动，改善工业工艺流的回收和城市废水的再利用。我们讨论了与电驱动分离技术的应用、实施和技术经济评估相关的关键方面。电驱动工艺通过降低盐度和选择性分离污染物，同时回收有价值的产品，提高环境可持续性，为提高循环水经济提供了可行的选择。

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
