“…Membrane capacitive deionization, electrodialysis membrane, and electrochemical filtration systems are the major examples of selective electrochemical membranes. These processes have easily found their way to versatile applications, e.g., desalination, energy production and resources recovery from waste streams, and wastewater disinfection [ 269 ]. Typically, an electrochemical system comprises a semi-permeable ion exchange membrane placed in between the cathode and anode ( Figure 12 ).…”

“…Depending on the charged group associated with the monopolar ion exchange membrane it could be either an anion-exchange or cation exchange membrane [ 271 ]. Membrane material selection is crucial to determine ionic properties bestowed upon the system performance [ 269 ]. Likewise, membrane capacitive deionization (MCDI) is a modified form of the classical capacitive deionization (CDI) process where membranes are integrated into the system.…”

Membrane Technologies for Nitrogen Recovery from Waste Streams: Scientometrics and Technical Analysis

The concerns regarding the reactive nitrogen levels exceeding the planetary limits are well documented in the literature. A large portion of anthropogenic nitrogen ends in wastewater. Nitrogen removal in typical wastewater treatment processes consumes a considerable amount of energy. Nitrogen recovery can help in saving energy and meeting the regulatory discharge limits. This has motivated researchers and industry professionals alike to devise effective nitrogen recovery systems. Membrane technologies form a fundamental part of these systems. This work presents a thorough overview of the subject using scientometric analysis and presents an evaluation of membrane technologies guided by literature findings. The focus of nitrogen recovery research has shifted over time from nutrient concentration to the production of marketable products using improved membrane materials and designs. A practical approach for selecting hybrid systems based on the recovery goals has been proposed. A comparison between membrane technologies in terms of energy requirements, recovery efficiency, and process scale showed that gas permeable membrane (GPM) and its combination with other technologies are the most promising recovery techniques and they merit further industry attention and investment. Recommendations for potential future search trends based on industry and end users’ needs have also been proposed.

“…Electromembrane processes, such as electrodialysis, fuel cells, redox flow batteries, reverse electrodialysis, and water electrolysis, fulfil separation at the ion level and show great potential in the fields of green production, energy conservation and storage, emission reduction, and energy transformation. [2][3][4][5][6][7] IEM-based separation and reaction processes have the potential to transform traditional chemical industries and will play a key role in revolutionizing related industries, such as the biological, pharmaceutical, food, and hydrometallurgical industries. These processes will also become important for solving the pollution issues in these fields.…”

Ion exchange membranes (IEMs) that can selectively transport ions are crucial to a variety of applications, such as ion extraction/separation, fuel cells, redox flow batteries, and water electrolysis. IEM performance, in terms of membrane permeability/conductivity and selectivity, relies heavily on the formation of effective ion transport channels within the membranes, and there exists a tradeoff between permeability/conductivity and selectivity, which obstructs the development and widespread adoption of IEM-based processes. To overcome this tradeoff and to advance IEM-related applications, extensive research efforts are devoted to the construction and tuning of ion transport channels, and various strategies are proposed. These strategies mainly include 1) inducing microphase separation by properly regulating the polymer architecture, 2) introducing a third phase/region for ion transfer, 3) realizing a high free volume with polyrotaxanes or polymers with sterically bulky groups, and 4) constructing ion transport channels with nanoporous materials. These strategies are outlined and summarized in this review. Perspectives and future research directions are also discussed.

A novel non-plasticized nano-porous hybrid inorganic-organic polymer inclusion membrane (PIM) was synthesized, characterized, and evaluated as an anion exchange membrane for application in electrogenerative processes to recover Pd2+ ions. Ionic liquids 1-ethyl-3-methylimidazolium chloride (EMIM-Cl) and 1-butyl-3-methylimidazolium chloride (BMIM-Cl) were used as the carrier molecules in the polymeric network of PIM to enhance anion exchange process. This hybrid anion exchange membrane also consists of a polymeric matrix of non-plasticized cellulose triacetate modified by incorporating an inorganic material (silane) prepared by the sol-gel route. Different parameters affecting the ion transport performance efficiency, i.e., the composition of the membrane, type of ionic liquid (carrier molecule) and ion–exchange capacity, were investigated and optimized. In the electrogenerative process, the results revealed that the prepared PIM yields better recovery results for recovering Pd2+ ions from its chloride solution compared to the commercial anion exchange membrane Neosepta® AM-01, with a full recovery of 100 mg/L Pd2+ ions in 30 min. This preliminary study shows that the prepared low-cost hybrid anion exchange membrane PIM can act as an inexpensive material suitable for the rapid and efficient recovery of Pd2+ ions from an aqueous solution.
