	Organic acids are a class of essential commodity chemicals used in various industries. Their production methods are shifting from conventional chemicals to fermentation, driven by green process strategies, environmental regulations, cost feasibility, etc. Separating formed acid from the fermentation broth is a primary technological barrier. Conventional methods are complex and impose environmental issues. A promising approach, `Chemodialysis,' capable of transforming the techno-economical feasibility of acid recovery scenario by reducing the number of steps, needs further investigation. This work evaluates scalable hollow fiber membranes based on poly(2,5-benzimidazole) (ABPBI) for chemically assisted dialysis, viz., Chemodialysis. Sorption analyses of commercially significant organic acids (acetic, lactic, and glycolic acid) and nonacidic solutes (NaCl and glucose) were performed using conventional flat sheet samples to assess their role in governing permeation characteristics. The transport properties of acids in the presence of NaCl and glucose as co-solutes were analyzed using hollow fiber membranes. The high selectivity of acid over nonacidic solutes ranges from 400-22,400, coupled with high acid permeability, enhances the applicability of Chemodialysis for the separation of acids using hollow fiber membranes. The fluxes of acids (acetic, glycolic, and lactic) through dense, similar to 100 mu m thick, scalable hollow fiber membranes ranging from 10.9 to 13.12 g/m(2)h are highly appreciable.&lt;/p&gt;

	We present poly(2,5-benzimidazole) (ABPBI) based membranes, doped with orthophosphoric acid (OPA), for the sorption and pervaporative dehydration of key industrial solvents: tetrahydrofuran (THF), acetonitrile (AN), and 1,4-dioxane (DX). The ABPBI-OPA complexes were formed via protonation and hydrogen bonding, as supported by spectroscopic and structural analyses. These complexes exhibited improved separation efficacy, further enhanced by thermal treatment. The separation factors for aprotic solvent:water mixtures (85/15 w/w%) were 115 +/- 7 for THF, 350 +/- 27 for AN, and 242 +/- 92 for DX. Long-term stability tests were conducted for 360 h to evaluate the membrane stability during the dehydration of azeotropic mixtures. The present work also introduces a drying approach for hollow fiber membrane modules to restore membrane performance. The results highlight the potential of the developed membranes for the dehydration of harsh solvents and for azeotrope-breaking applications, with no observable membrane degradation over the investigated period.&lt;/p&gt;
