How to Identify AEM, CEM, and BPM Membranes Using Methylene Blue and Methyl Orange(Ions Exchange Membrane Identify)
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).
Electrochemical Separation and Recovery of High-Purity Hydrochloric Acid and Ammonium Hydroxide from Ammonium Chloride via Bipolar Membrane Electrodialysis
This study investigates the technical feasibility of employing bipolar membrane electrodialysis (BMED) for the simultaneous recovery of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) from ammonium chloride (NH4Cl) waste streams.
Inorganic Flocculants for Water and Wastewater Treatment: A Practical Guide
Flocculants play a critical role in modern water and wastewater treatment, helping industries and municipalities achieve cleaner water, higher efficiency, and regulatory compliance. While many professionals are familiar with the term, understanding which flocculant to use, how it works, and when to apply it can still be challenging.
YASA ET Signs MoU with Pangasinan State University to Advance Seawater Salt Production Technology
YASA ET has officially signed a Memorandum of Understanding (MoU) with Pangasinan State University, marking a significant step forward in international cooperation on seawater salt production and desalination technologies. Under this partnership, YASA ET will provide its proprietary DESALT® electrodialysis (ED) concentration technology, designed to efficiently concentrate seawater to more than 15% salinity.
Electrodialysis and Bipolar Membrane Electrodialysis (EDBM) for Efficient Conversion of Na2SO4 to H2SO4 and NaOH: A Pilot-Scale Study
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.
Electrodialysis and Bipolar Membrane Electrodialysis (EDBM) for Efficient Conversion of NaCl to HCl and NaOH: A Pilot-Scale Study
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).
