Electrodialysis Reversal (EDR) is a proven and highly efficient technology for separating dissolved ions from water and process liquids using an electrical potential. By combining ion-selective membranes with controlled polarity reversal, EDR delivers reliable desalination, concentration, and purification across a wide range of industrial applications.

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.

As traditional water treatment methods struggle to meet the demand, electrodialysis (ED) has emerged as an efficient and sustainable solution for desalinating brackish water and treating complex industrial effluents. This article explores the performance and advantages of YASA ET’s DESALT electrodialysis equipment, using real-world data from a comprehensive pilot-scale study.

As industries and municipalities rely more heavily on Reverse Osmosis (RO) for water purification, the challenge of managing RO reject, a concentrated brine stream, becomes increasingly urgent. DESALT Electrodialysis Reversal (EDR) technology offers a modern, energy-efficient, and cost-effective method to concentrate RO reject while maximizing water recovery.
