MORE INFORMATION AND RESOURCES ABOUT ELECTRODIALYSIS

In electrodialysis (ED) and bipolar electrodialysis (EDBM) systems, correct membrane identification and orientation are essential to ensure efficient ion transport and system performance. A simple and effective laboratory method uses two common dyes—Methylene Blue and Methyl Orange—to distinguish between Anion Exchange Membranes (AEM), Cation Exchange Membranes (CEM), and Bipolar Membranes (BPM).

This study demonstrates the performance of the YASA ET pilot-scale electrodialysis (ED) and bipolar membrane electrodialysis (EDBM) system for the conversion of sodium sulfate (Na2SO4) into sulfuric acid (H2SO4) and sodium hydroxide (NaOH). Using a 10-pair Saifu EDBM stack, the system operated under constant applied voltage (20 V) and controlled flow conditions.

This study demonstrates the operation of the YASA ET pilot-scale electrodialysis (ED) and bipolar membrane electrodialysis (EDBM) system in the conversion of sodium chloride (NaCl) to hydrochloric acid (HCl) and sodium hydroxide (NaOH).

This study investigates sodium chloride (NaCl) concentration using a pilot-scale DESALT® electrodialysis (ED) system (YASA ET) under constant-voltage operation (14 V) in batch recirculation mode. The system, featuring a Saifu stack with ten cell pairs of alternating anion- and cation-exchange membranes, demonstrated efficient ion transport and strong membrane selectivity.
