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).
Sodium Chloride Concentration and Desalination Using a Pilot-Scale DESALT® Electrodialysis System: Performance and Energy Efficiency
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.
Experimental Study of NaCl Electrodialysis Using DESALT Pilot Equipment
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...
