“…Point B on the “knee” of equilibrium isotherms characterizes the transition from monomolecular to polymolecular adsorption (section II). An indirect confirmation of the polymolecular adsorption of anthocyanins is the identification of dimers and trimers of these substances in ion-exchange membranes [ 110 ] that had a chemical structure similar to the studied resins and put in contact with anthocyanin-containing solutions. Among the reasons for such polymolecular adsorption are the π–π (stacking) interaction of the aromatic rings of polyphenols with each other [ 29 , 50 ] or with substances with the opposite electric charge at a given pH [ 111 ].…”

This study examines the mechanisms of adsorption of anthocyanins from model aqueous solutions at pH values of 3, 6, and 9 by ion-exchange resins making the main component of heterogeneous ion-exchange membranes. This is the first report demonstrating that the pH of the internal solution of a KU-2-8 aromatic cation-exchange resin is 2-3 units lower than the pH of the external bathing anthocyanin-containing solution, and the pH of the internal solution of some anion-exchange resins with an aromatic (AV-17-8, AV-17-2P) or aliphatic (EDE-10P) matrix is 2–4 units higher than the pH of the external solution. This pH shift is caused by the Donnan exclusion of hydroxyl ions (in the KU-2-8 resin) or protons (in the AV-17-8, AV-17-2P, and EDE-10P resins). The most significant pH shift is observed for the EDE-10P resin, which has the highest ion-exchange capacity causing the highest Donnan exclusion. Due to the pH shift, the electric charge of anthocyanin inside an ion-exchange resin differs from its charge in the external solution. At pH 6, the external solution contains uncharged anthocyanin molecules. However, in the AV-17-8 and AV-17-2P resins, the anthocyanins are present as singly charged anions, while in the EDE-10P resin, they are in the form of doubly charged anions. Due to the electrostatic interactions of these anions with the positively charged fixed groups of anion-exchange resins, the adsorption capacities of AV-17-8, AV-17-2P, and EDE-10P were higher than expected. It was established that the electrostatic interactions of anthocyanins with the charged fixed groups increase the adsorption capacity of the aromatic resin by a factor of 1.8–2.5 compared to the adsorption caused by the π–π (stacking) interactions. These results provide new insights into the fouling mechanism of ion-exchange materials by polyphenols; they can help develop strategies for membrane cleaning and for extracting anthocyanins from juices and wine using ion-exchange resins and membranes.

“…Unfortunately, because the composition of tobacco extract is very complex, the possible fouling agents are difficult to be identified. However, considering that the tobacco extract is also one kind of plant juice, it is speculated that the possible fouling agents are the large-sized carboxylic acids such as humic acids, polyphenols, negative peptide charges (COO − ), and amino acids [ 38 , 39 , 40 ]. For the cation exchange membrane, the fouling was mainly caused by minerals.…”

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.

“…This increase is not only related to a high rate of hydration of organic species fixed to charged sites, but also to their accumulation inside the membrane matrix within the interstices and uncharged pores caused by the degradation or loss of polymer fragments. Bdiri et al [33,39] demonstrated that the water content of the anion-and [14] cation-exchange membranes AMX-Sb and CMX-Sb (Astom, Japan) increased by ≈50% after almost 2500 h of use in ED treatment of red wines. They observed that this increase was accompanied by a simultaneous increase in the linear dimensions of the membranes, wich suggested that highly hydrated substances were introduced into the IEMs and stretch the polymer matrix.…”

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.
