This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and other treatments with significant environmental benefits. ED technologies can be used in operations of concentration, dilution, desalination, regeneration, and valorisation to reclaim wastewater and recover water and/or other products, e.g., heavy metal ions, salts, acids/bases, nutrients, and organics, or electrical energy. Intense research activity has been directed towards developing enhanced or novel systems, showing that zero or minimal liquid discharge approaches can be techno-economically affordable and competitive. Despite few real plants having been installed, recent developments are opening new routes for the large-scale use of ED techniques in a plethora of treatment processes for wastewater.

“…Hence, care must be taken in the operation of ED with heterogeneous membranes at over-limiting current regimes for water with a high fouling propensity. Studying the over-limiting current operation of ED for various feed waters [ 269 , 270 ], investigating the effects on transport mechanisms [ 271 , 272 ], and identifying approaches to modify membrane characteristics [ 273 , 274 ] are ongoing research directions.…”

Frontiers of Membrane Desalination Processes for Brackish Water Treatment: A Review

et al. 2021

Climate change, population growth, and increased industrial activities are exacerbating freshwater scarcity and leading to increased interest in desalination of saline water. Brackish water is an attractive alternative to freshwater due to its low salinity and widespread availability in many water-scarce areas. However, partial or total desalination of brackish water is essential to reach the water quality requirements for a variety of applications. Selection of appropriate technology requires knowledge and understanding of the operational principles, capabilities, and limitations of the available desalination processes. Proper combination of feedwater technology improves the energy efficiency of desalination. In this article, we focus on pressure-driven and electro-driven membrane desalination processes. We review the principles, as well as challenges and recent improvements for reverse osmosis (RO), nanofiltration (NF), electrodialysis (ED), and membrane capacitive deionization (MCDI). RO is the dominant membrane process for large-scale desalination of brackish water with higher salinity, while ED and MCDI are energy-efficient for lower salinity ranges. Selective removal of multivalent components makes NF an excellent option for water softening. Brackish water desalination with membrane processes faces a series of challenges. Membrane fouling and scaling are the common issues associated with these processes, resulting in a reduction in their water recovery and energy efficiency. To overcome such adverse effects, many efforts have been dedicated toward development of pre-treatment steps, surface modification of membranes, use of anti-scalant, and modification of operational conditions. However, the effectiveness of these approaches depends on the fouling propensity of the feed water. In addition to the fouling and scaling, each process may face other challenges depending on their state of development and maturity. This review provides recent advances in the material, architecture, and operation of these processes that can assist in the selection and design of technologies for particular applications. The active research directions to improve the performance of these processes are also identified. The review shows that technologies that are tunable and particularly efficient for partial desalination such as ED and MCDI are increasingly competitive with traditional RO processes. Development of cost-effective ion exchange membranes with high chemical and mechanical stability can further improve the economy of desalination with electro-membrane processes and advance their future applications.

“…Electromembrane [1][2][3][4][5] processes and other membrane technologies [6], along with their conventional fields of application, have been used as a reagentless method for correcting the composition of process solutions [7] and extracting certain components from them, including undesirable impurities and reaction products. In many cases, they can be used to recover valuable and toxic components of rinse water in order to return them to the process and create closed (wastefree) production cycles.…”

Electromembrane processes have been used to reduce 100-1000 times the carryover of cadmium ions from cadmium electroplating baths into electroplating wastewater. Laboratory experiments and industrial practice have shown that the efficiency of the process depends on the type of cadmium plating electrolyte used: it is maximum for cyanide electrolytes (cadmium recovery efficiency is 99.9%) and minimum for sulfuric acid electrolytes free of ammonium ions (recovery efficiency is 99%). The technology and equipment developed are used in a number of industrial plants.
