“…14 BMED particularly satisfies the sustainability of the modern industrial ecology because it perfectly integrates the advantages of accelerated water dissociation in a bipolar membrane and the oriented ion migration in the conventional ED. Therefore, BMED has been applied for environmental protection, resource recovery, food processing [15][16][17] as well as cleaner production of organic and amino acids such as citric acid, 18 lactic acid, 19 methionine, 20 acetic acid, 21 gluconic acid, 22 formic acid, 23 succinic acid, 24 and among others. 25 When BMED is performed to produce L-CSA, this technology allows the concurrently conversion of ammonium camphorsulfonate into targeted product and the generation of ammonia that can be recycled to the upstreaming procedure as raw chemicals to achieve a closed loop production (Figure 1).…”

In this study, bipolar membrane electrodialysis (BMED) was implemented for cleaner production of L-10-camphorsulfonic acid (L-CSA) to lower the environmental impact.Under the current density of 300-400 A/m 2 and feed salt concentration of 6-10 wt. %, the energy consumption and current efficiency were 2.24-2.70 kWh/kg and 20.89-29.5%, respectively. Positron annihilation lifetime spectroscopy, x-ray photoelectron spectroscopy with ion beam etching, and other characterizations were used to elucidate the transport behaviors of large-sized anions across the membranes. It was speculated that the large-sized camphor sulfonate ions were more likely to deposit on the surface of the anion-exchange membrane to form a deposition layer under a direct current electric field. The appearance of water splitting at this deposition layer would offset the water dissociation in the bipolar membrane. Nevertheless, the successful commissioning of industrial-scale stack proved the feasibility and sustainability of BMED technique for a closed loop L-CSA production.

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.

“…When the voltage drop changes from 6 to 8 V, the experimental time decreases from 65 to 55 min, respectively. This can be ascribed to the higher voltage drop resulting in higher driving force, thus a lower experimental time . At the same voltage drop, the maximum current exhibits an upward trend with an increase of operating step number, which is ascribed to the increase of the conductivity in the concentrated solution.…”

A novel industrial lithium-containing wastewater depth concentrating process integrating reverse osmosis (RO) and electrodialysis (ED) into a system is presented. A systematic analytical study was accomplished to optimize the studied parameters and minimize the energy consumption. The tested parameters were as follows: RO recovery by adding pressure, ED voltage drop, the concentration of RO retentate in ED feed solution, ED volume ratio, and ED operating mode. By using RO retentate instead of initial wastewater in the ED process, water energy consumption was reduced by 3.41 times from 26.67 to 7.81 kW h/m3, while optimizing the RO retentate concentration for the ED feed solution reduced the cost to 0.47 $/kg. The results showed that RO is crucial to preconcentrate lithium salt and save energy. Furthermore, the final LiCl concentration can approach as high as 87.09 g/L with the secondary ED process (V d:V c = 3:1), while the energy consumption can be saved as 7.71 kW h/m3 when the experiments stopped in region 1. The concentration factor of 12.32 can be achieved to justify the feasibility of integration of a high volume ratio concentrating with a mutistage concentrating protocol. As a consequence, the hybrid RO–ED process allows for lithium salt extraction and concentrating from industrial lithium-containing wastewater, which is appropriate for industrial applications.
