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.

This study presents a systematic performance analysis of NaCl desalination using a DESALT Pilot ED unit. The primary objective is to elucidate the fundamental correlations between ion transport, evidenced by conductivity changes, and the resulting electrical and energy profiles under constant voltage operation. By monitoring the temporal evolution of current density and cumulative energy consumption...

Diffusion Dialysis (DD) is one of the most energy-efficient membrane technologies available today for acid recovery and industrial wastewater treatment. YASA ET’s DD Laboratory Test System, built with our YTDD-series ion-exchange membranes, provides a compact, reliable, and highly repeatable platform for testing acid–water separation performance in real industrial conditions.

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.

In modern wastewater treatment and laboratory processes, water purity is essential. You’ll often hear terms like ultrapure water, deionized water, reverse osmosis (RO) water, distilled water, and double distilled water—but what do these actually mean? To help you understand, YASA Environmental Technology (YASA ET) engineers have explained the differences, standards, and practical uses of these water types and how they impact industrial and laboratory applications.
