“…The recent results of membrane development should be taken into account in the industrial implementation, thus the maintenance costs (Zhao et al 2021b), energy demand (Yan et al 2018) and product purity (Liao et al 2020;Yan et al 2020) can be beneficially affected. Specific energy consumption from experimental results, however, can be taken as an indicator of the economic viability of the process (Zhao et al 2021a).…”

Organic acids, e.g, citric acid, fumaric acid, lactic acid, malic acid, pyruvic acid and succinic acid, have important role in the food industry and are potential raw materials for the sustainable chemical industry. Their fermentative production based on renewable raw materials requires innovatively designed downstream processing to maintain low environmental impact and resource efficiency throughout the production process. The application of bipolar membranes offers clean and effective way to generate hydrogen ions required for free acid production from its salt. The water dissociation reaction inside the bipolar membrane triggered by electric field plays key role in providing hydrogen ion for the replacement of the cations in organic acid salts. Combined with monopolar ion-exchange membranes in a bipolar membrane electrodialysis process, material flow can be separated beside the product stream into additional reusable streams, thus minimizing the waste generation. This paper focuses on bipolar membrane electrodialysis applied for organic acid recovery from fermentation broth.

“…Till now, various approaches such as adsorption (Reyhanitash et al 2017), solvent extraction (Schlosser et al 2005), electrodialysis (Zhao et al 2021), membrane filtration (Zacharof and Lovitt 2013), esterification (Plácido and Zhang 2018) and so on have been attempted to recover VFAs from anaerobic fermentation broth. However, pressure-driven membrane filtration has particularly been selected as an CEST2021_00160 effective option for the sustainable recovery of VFAs because of their numerous advantages (Aghapour Aktij et al 2020;Zhu et al 2021).…”

Currently, petroleum-based volatile fatty acids (VFAs) sources are not acceptable towards sustainable development goals (SDG); therefore, biobased-derived VFAs are of interest. Anaerobic digestion has been identified as a useful technology for the production of biobased VFAs from organic waste residue because of their environmental sustainability, easy operation and affordability. The anaerobically digested liquid comprises several inorganic and organic compounds/particles, including VFAs, which is one of the main challenges nowadays since the particles/compounds free VFAs are highly demanded. Hence, pressure-driven membrane filtration technologies (microfiltration, ultrafiltration, nanofiltration and reverse osmosis) is being widely used due to their higher VFAs recovery efficiency. Microfiltration and ultrafiltration usually applied as pretreatment for removing coarser particles, while nanofiltration and reverse osmosis possess a remarkable role in recovery performances. This report is highlighted on the various types of membrane used for VFAs recovery percentages and critically discuss their influence. Afterwards, it was confirmed that lower pore size membranes offer better recovery percentages of VFAs over higher pore size membranes due to their permeability rate.
