In the context of preserving and improving human health, electrodialytic processes are very promising perspectives. Indeed, they allow the treatment of water, preservation of food products, production of bioactive compounds, extraction of organic acids, and recovery of energy from natural and wastewaters without major environmental impact. Hence, the aim of the present review is to give a global portrait of the most recent developments in electrodialytic membrane phenomena and their uses in sustainable strategies. It has appeared that new knowledge on pulsed electric fields, electroconvective vortices, overlimiting conditions and reversal modes as well as recent demonstrations of their applications are currently boosting the interest for electrodialytic processes. However, the hurdles are still high when dealing with scale-ups and real-life conditions. Furthermore, looking at the recent research trends, potable water and wastewater treatment as well as the production of value-added bioactive products in a circular economy will probably be the main applications to be developed and improved. All these processes, taking into account their principles and specificities, can be used for specific eco-efficient applications. However, to prove the sustainability of such process strategies, more life cycle assessments will be necessary to convince people of the merits of coupling these technologies.

Recently, water scarcity, world population rise and urbanization are causing desalting of seawater. Membrane separation processes such as reverse osmosis are applied for desalination over the conventional mass transfer techniques. For instance, reverse osmosis accounts for the treatment of nearly 1% of the world water supply and its applications are increasing with time. However, cost, technical management and efficiency are challenging aspects. Hence, membrane fouling, direct and indirect investment costs, and permeate quality are the major hurdles encountered. Toward solving these problems, various studies are being conducted including varying membrane operating conditions and separation methodologies whereby ionexchange-reverse osmosis hybrids and the coupling of two or more other membrane filtration techniques can be mentioned. Apparently, most of the hybrid techniques targeted for the selective removal of a pollutant. Hence, ion exchange-reverse osmosis is the most applied hybrid process particularly for boron removal due to its public and environmental health impact. Despite that, there is no current and comprehensive review that bridged the piece by piece and fragmented reports. In this review, desalination-ion-exchange coupling with other membrane filtration is explored in detail and the recent advances in composite membrane material synthesis are uncovered. Further, the status, cost and future potential of hybrid membranes are discussed and gaps are identified for future research.
