“…Recently, a modified SED stack, selectrodialysis with bipolar membrane (BMSED) has been developed to extend the applicability of this technology. Taking advantage of the ability of bipolar membranes to generate hydrogen and hydroxide ions, as well as the retention of divalent ions by monovalent permselective membranes, BMSED was successfully implemented for base/acid production [ 167 ], and lithium hydroxide production [ 168 ].…”

“…Although researchers are studying more complex effluents for specific ion recovery, SED prototypes still exhibit moderate current efficiencies for divalent ions, up to 43% for SED and 58% for BMSED [ 157 , 167 , 168 ]. A significant drawback for SED is the cost of MVCs and MVAs compared to IEMs, however Jiang et al [ 169 ] recently developed a new way to prepare these membranes by fouling deposition.…”

“…Lithium is not used exclusively for the production of Li-ion batteries, but also involved in CO 2 purification and nuclear energy production among others [ 191 , 225 ]. As ionic lithium is naturally occurring in salt lakes along with other cations such as Mg 2+ , extraction technologies have been developed, among which ED exhibit the lowest energy consumption [ 168 ]. Jiang et al [ 191 ] implemented an ED-EEDBM in order to produce high-purity LiOH.…”

“…The high current efficiency achieved (99%) and moderate energy consumption (8 kWh/kg) led to better performances than ED alone. Using a similar strategy, Qiu et al [ 168 ] produced LiOH by SED-BMSED. Using monovalent permselective IEMs led to an improved selectivity for Li + vs. other cations Mg 2+ and Ca 2+ , both during pre-concentration by SED and LiOH production with BMSED.…”

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.

To improve sulfuric acid recovery from sodium sulfate wastewater, a lab-scale bipolar membrane electrodialysis (BMED) process was used for the treatment of simulated sodium sulfate wastewater. In order to increase the concentration of sulfuric acid (H2SO4) generated during the process, a certain concentration of ammonium sulfate solution was added into the feed compartment. To study the influencing factors of sulfuric acid yield, we prepared different concentrations of ammonium sulfate solution, different feed solution volumes, and different membrane configurations in this experiment. As it can be seen from the results, when adding 8% (NH4)2SO4 into 15% Na2SO4 under the experimental conditions where the current density was 50 mA/cm2, the concentration of H2SO4 increased from 0.89 to 1.215 mol/L, and the current efficiency and energy consumption could be up to 60.12% and 2.59 kWh/kg, respectively. Furthermore, with the increase of the volume of the feed compartment, the concentration of H2SO4 also increased. At the same time, the configuration also affects the final concentration of the sulfuric acid; in the BP-A-C-BP (“BP” means bipolar membrane, “A” means anion exchange membrane, and “C” means cation exchange membrane; “BP-A-C-BP” means that two bipolar membranes, an anion exchange membrane, and a cation exchange membrane are alternately arranged to form a repeating unit of the membrane stack) configuration, a higher H2SO4 concentration was generated and less energy was consumed. The results show that the addition of the double conjugate salt is an effective method to increase the concentration of acid produced in the BMED process.

Lithium demands increase dramatically and make it highly attractive to develop advanced ion separation technology/material. However, high Mg2+/Li+ ratio impedes the extraction due to the difficulties in separation of the two ions. Here, we propose an ion‐“distillation” technology based on electro‐membrane stacking for the extraction of Li+ from lake brine (Mg2+/Li+ ratio: 31.58). This technology employs commercially available monovalent ion‐selective membranes, and ions are driven by electric. Using the four‐stage ion‐“distillation” technology, selectivity values of 26,177 and 27,000 are achieved between Li+ and Mg2+ and between Cl− and SO42−, respectively. The electro‐stripping mechanism when monovalent ion migrating across the membranes probably magnitude the Li+ selectivity, which is higher than the other reported values in the literature for membrane processes, and the purity of the final LiCl product is greater than battery grade (99.95%). The proposed process can potentially be applied in efficient ion fractionation and special separations.
