“…The PDA layer favors the migration of monovalent anions through the membrane but hinders the multi-valent anions. 9,32 However, aer TMC coating, the membrane resistance decreased from 11.48 U cm 2 for the PP membrane to 10.42 U cm 2 for the PPT membrane. It is expected that as a result of the TMC coating the membrane surface became denser, leading to an increase of the membrane resistance.…”

“…[27][28][29][30][31] Besides, dopamine can also be used for preparing monovalent selective anion membranes due to the dense structure or negative charge properties of the modied membrane surface. 9,32,33 These characteristics make PDA a good candidate material to control the compactness and the surface charge of these nanoltration membranes inspired asymmetric porous membranes. In this study, a new application possibility is explored: nanoltration membrane inspired asymmetric porous membranes were proposed as monovalent selective anion membranes in ED.…”

“…Physical and chemical alterations of the membrane surface are used to adjust surface charge density, increase the hydrophilicity, and reduce the roughness. Increasing the negative charge density and hydrophilicity of the surface through coating a polyelectrolyte or a thin nanocomposite layer on the surface has enhanced the antifouling properties of the membranes [ 298 , 299 , 300 ]. However, these surface coatings may result in an increase in surface roughness, adversely affecting AEM fouling resistance [ 285 ].…”

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

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.

“…One of the main advantages of this method is that potential organic foulants, such as proteins, peptides, polysaccharides or biofoulants, could be stained with different fluorescent probes which facilitates the quantitative characterization and the visualization of fouling and polymer adsorption, and could lead to the de-termination of the possible interactions between proteins and membranes. For example, Reichert et al [142] studied CLSM images to investigate the adsorption of two model proteins, BSA and lysozyme on commercially available CEM (Sartobind S) and AEM (Sartobind Q) for the protein purification process (Figure 20), Vaselbehagh et al [143] com-pared CLSM images of PDA-modified AMX (Neosepta-Astom, Japan) carried out to improve the biofouling resistance of the membrane during ED treatments and it was possible to clearly observe stained viable bacteria on the surface; Herzberg et al identified living and dead cells on the surface of various CEMs and AEMs [144]. While interest in the CLSM method is growing, it remains less used than SEM and AFM.…”

Electrodialysis (ED) was first established for water desalination and is still highly recommended in this field for its high water recovery, long lifetime and acceptable electricity consumption. Today, thanks to technological progress in ED processes and the emergence of new ion-exchange membranes (IEMs), ED has been extended to many other applications in the food industry. This expansion of uses has also generated several problems such as IEMs’ lifetime limitation due to different ageing phenomena (because of organic and/or mineral compounds). The current commercial IEMs show excellent performance in ED processes; however, organic foulants such as proteins, surfactants, polyphenols or other natural organic matters can adhere on their surface (especially when using anion-exchange membranes: AEMs) forming a colloid layer or can infiltrate the membrane matrix, which leads to the increase in electrical resistance, resulting in higher energy consumption, lower water recovery, loss of membrane permselectivity and current efficiency as well as lifetime limitation. If these aspects are not sufficiently controlled and mastered, the use and the efficiency of ED processes will be limited since, it will no longer be competitive or profitable compared to other separation methods. In this work we reviewed a significant amount of recent scientific publications, research and reviews studying the phenomena of IEM fouling during the ED process in food industry with a special focus on the last decade. We first classified the different types of fouling according to the most commonly used classifications. Then, the fouling effects, the characterization methods and techniques as well as the different fouling mechanisms and interactions as well as their influence on IEM matrix and fixed groups were presented, analyzed, discussed and illustrated.
