“…Besides, Eliseeva et al 24 studied the ED process of solutions of tartaric acid and its salts, achieving tartaric acid percentage removal of 62% (see Table 3). In this work, seven cell pairs with a membrane area of 20 cm 2 and a membrane configuration (anode)-AEM-CEM-(cathode) was used in comparison with the CEM-AEM-CEM used in this work (89.4 ± 3.4% KHT desalting using Fujifilm membranes).…”

“…For example, the (anode)-CEM-AEM-(cathode) configuration was used in the ED process for tartaric acid and potassium recovery . On the other hand, the (anode)-AEM-CEM-(cathode) configuration was also proposed for tartaric acid valorization. , Indeed, Zhang et al investigated the production of tartaric acid by electrometathesis (EDM) applying different current densities (300–600 A/m 2 ), adding resin or without adding it in the EDM process. The ion-exchange membranes (CEM and AEM) were supplied by QianQiu Environmental Protection & Water Treatment Corporation.…”

“…They observed that tartrate ions maintained the typical transport characteristics for an anion-exchange membrane/solution system. In addition, Eliseeva et al 24 studied the transport of L-tartaric acid and its salt (e.g., potassium hydrogen tartrate) through ionexchange membranes by ED (MK-40 CEM, MA-41 AEM, and MB-3 BPM). They observed that the dependence of hydrogen tartrate ion flux on current density was characterized by a plateau existence in the barrier effect region, thereby increased in the mass transfer in the facilitated electromigration effect region of ED.…”

One of the challenges of the circular economy is to implement the recovery of resources from the generated waste in each industrial sector. This valorization must be one of the main objectives at the industrial level to be economically and financially sustainable and, at the same time, reduce the environmental impact. This work focuses on this perspective through the valorization of distilled vinasses from the winery industry by means of tartaric acid recovery. A train of membrane processes was experimentally tested for the distilled vinasses treatment: electrodialysis (ED) followed by electrodialysis with bipolar membranes (EDBM). The ED process was evaluated by varying the membrane configuration (sequence in the cell unit), type of membrane (different membrane properties), and type of solution (synthetic and distilled vinasses from the winery industry). Distilled vinasses, which mainly contained potassium hydrogen tartrate (KHT), were treated in a lab-scale set-up with standard and organic selective anionic-exchange membranes (AEM), as well as cationic-exchange membranes (CEM) for ED and also with bipolar membranes (BPM) for EDBM. The results indicated that it was possible to concentrate the KHT contained in the distilled vinasses with a factor of 2 by ED, using standard membranes from Fujifilm with the CEM-AEM-CEM configuration, and subsequently to produce 9.9 g/L of tartaric acid (H2T) and 5.6 g/L of potassium hydroxide (KOH) by EDBM (following the (anode)-CEM-BPM-AEM-CEM-(cathode) configuration and Fujifilm standard and PCCell BP membranes) with a purity of 69.7 ± 1.3 and 77.3 ± 0.3%, respectively. In conclusion, the integration methodology proposed (ED and EDBM) demonstrated to be promising for the recovery of tartaric acid from distilled vinasses following the circular economy approach.

“…Properties of the transport of ions depend on the nature of the polymer matrix, extent of the crosslinking, and fixed concentration of the ionic charges [14]. These carboxylic acid-containing compounds are the fermentation product of sugar molasses and starch hydrolysates [15,16]. Subsequently, it is essential to remove these from the fermented components.…”

“…The extraction and precipitation of these organic acids requires a large amount of reagents and generate a substantial volume of waste water containing a higher concentration of mineral salts. Therefore, such electromembranes are not only efficient in the separation and purification of carboxylic acid-containing compounds from the fermented broth, they also make the process environmentally benign [16].…”

Recently, membrane-based separation processes, particularly electrodialysis, have attracted attention for the separation and purification of organic and amino acids from animal feedstock waste. In this study, cation exchange membranes were synthesized by making a composite of thermoplastic polyurethane and polyaniline (PANI) via the doping of various aromatic sulfonic acids, such as β-naphthol sulfonic acid and phenol sulfonic acid. The PANI was prepared using a standard method, which was further used in the composite blending at varying concentrations of 10%-20%. The impact of the concentration of PANI and the nature of the dopant on the membrane characteristics were comparatively studied. The membranes were analyzed by electric conductivity, water swelling, morphological studies (SEM), and thermogravimetric analysis. The membranes were used for the separation of glycine hydrochloride via electrodialysis.
