Comparison of different combinations of heterogeneous and homogeneous bipolar and ion exchange membranes in lab-scale electrodialysis stack

Original language description

Electrodialysis with bipolar membranes (EDBM) process can be utilized to generate acids and bases from their corresponding salts. This technique has diverse applications, including the reclamation of industrial wastewater, pH adjustment of various substances, and many others contributing to environmental conservation efforts. The objective of this study was to evaluate three different bipolar membranes (BMs) by testing them in a laboratory-scale EDBM setup along with several ion-exchange membranes. The results provide valuable insights into the utility of these membrane configurations across various industry sectors. The results indicated that the primary limitations of heterogeneous BMs are their high electrical resistances and limited selectivities. However, owing to their low cost and suitability for food-related applications, they are particularly useful in single-pass flow regimes or situations where minor pH modifications are sufficient, especially in food and beverage production. For scenarios where the production of high-concentration acids/bases is essential but purity is less critical, such as in CO2 capture technology or flue gas desulfurization, application of heterogeneous BMs along with homogeneous ion exchange membranes is recommended. In contrast, stacks composed entirely of homogeneous membranes are recommended for processes that require extremely pure and concentrated outputs as well as high water yields.
