“…In this case, the dissociated OH - ions of water will combine with Ca 2+ and Mg 2+ ions and will precipitate on the surface of cation exchange membranes. The substantial inorganic scaling fouling in the cation exchange membrane is consistent with numerous studies [ 41 , 42 , 43 , 44 ]. Cifuentes-Araya and co-authors [ 42 ] found that divalent cations precipitation with OH - ions produced by significant water splitting was reinforced by an important OH - leakage through CEM that highly alkalinized the membrane interfaces, and also counteracted the demineralization.…”

“…Cifuentes-Araya and co-authors [ 42 ] found that divalent cations precipitation with OH - ions produced by significant water splitting was reinforced by an important OH - leakage through CEM that highly alkalinized the membrane interfaces, and also counteracted the demineralization. In a previous study [ 43 ], the authors systematically investigated the fouling nature evolutions along with different ED trials, and they found that amorphous calcium carbonate appeared on cation exchange membrane due to intense water-splitting reaction. Dufton and co-authors [ 44 ] have studied the fouling of ED for acid via deacidification, and they found the calcite and brucite were identified on the cation exchange membrane.…”

In the papermaking industry (reconstituted tobacco), a large number of tobacco stems, dust, and fines are discharged in the wastewater. This high salinity wastewater rich in ionic constituents and nicotine is difficult to be degraded by conventional biological treatment and is a serious threat that needs to be overcome. Electrodialysis (ED) has proved a feasible technique to remove the inorganic components in the papermaking wastewater. However, the fouling in ion exchange membranes causes deterioration of membranes, which causes a decrease in the flux and an increase in the electrical resistance of the membranes. In this study, the fouling potential of the membranes was analyzed by comparing the properties of the pristine and fouled ion exchange membranes. The physical and chemical properties of the ion exchange membranes were investigated in terms of electrical resistance, water content, and ion exchange capacity, as well as studied by infrared spectroscopy (IR) spectra, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) analyses. The results indicated that the membrane fouling is caused by two different mechanisms. For the anion exchange membranes, the fouling is mainly caused by the charged organic anions. For the cation exchange membrane, the fouling is caused by minerals such as Ca2+ and Mg2+. These metal ions reacted with OH− ions generated by water dissociation and precipitated on the membrane surface. The chemical cleaning with alkaline and acid could mitigate the fouling potential of the ion exchange membranes.

“…Indeed, due to the disappearance of the boundary layer and the regular re-homogenization of the solution around the membranes, the PEFs have proven to be an effective solution to mitigate fouling caused by humate [ 39 , 102 ], proteins [ 103 , 104 ], peptides/amino acids [ 105 ], lignin [ 106 ], natural organic matter [ 107 ], partially hydrolyzed polyacrylamid [ 84 ] and mineral scaling [ 64 , 65 , 83 , 84 , 85 , 104 , 108 , 109 , 110 , 111 , 112 , 113 ] during electrodialytic processes ( Table 1 ). Deep investigations have been carried out to reveal the mechanisms of scaling prevention under the action of PEF [ 104 , 109 , 110 , 114 ] as well as fouling mitigation by natural organic matter [ 107 , 115 , 116 , 117 ] and lignin [ 106 ]. Regarding specific migration of mineral ions, the difference in monovalent and divalent ion demineralization caused by PEF could be explained by several points reported in the literature.…”

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.

“…Firstly, PEF technique was experimented to reduce the concentration polarization (CP) which is created when the ionic concentration at one side of the membrane is very low while the ionic concentration is very high on the other side of the same membrane, and increase the ED power efficiency [65]. The reducing of CP leaded also to the decrease of scaling and fouling tendencies especially in the case of ions, charged molecules and colloidal particles and important applications of pulsed current mode emerged as means to mitigate the formation of organic gel or inorganic crystalline films on membrane surface or modulate the mineral membrane fouling growth [66][67][68][69][70][71][72][73][74][75]. In particular, it was found that the use of pulsation with a frequency of the order of 0.1 Hz and an extended relaxation time allows the mitigation of organic fouling in the systems containing humate, lactate, bovine serum albumin (BSA) or whey protein [68,[76][77][78][79].…”

A Review on Ion-exchange Membranes Fouling and Antifouling During Electrodialysis Used in Food Industry: Cleanings and Strategies of Prevention

During the last decades, the interest of using ion-exchange membranes (IEMs) in electrodialysis (ED) technologies has emerged in wastewater treatment, drinking water and process water production as well as food industry and more recently in processes of energy conversion and storage. Like in all membrane technologies, the problem of fouling is one of the limitative phenomena of IEM efficiency and lifetime. It mainly leads to an increase in electrical resistance of ED stacks and consequently to increase operating and membrane replacement costs, which directly affects the cost of the final product. In food industry, the composition of the treated solutions and beverages is most often complex and rich in several organic and inorganic compounds which further increases the risks and effects of fouling. Hence, a better knowledge and understanding of IEM fouling phenomena is not only the key to solve the problems and find adequate solutions, but also is one of the main factors driving membrane technology forward. This review is mainly focused on the organic fouling phenomena of IEMs during ED processes in both food and water treatment industries. It principally presents the main cleaning techniques used in industry or experimented at laboratory scale and the recent strategies of fouling prevention.
