Electrodialysis (ED) is an electrochemical separation process widely used for desalination, concentration, and purification of solutions. This technology utilizes a stack of alternating anion- and cation-exchange membranes placed between two electrodes. When a DC voltage is applied, ions in the feed solution migrate through these selective membranes toward the oppositely charged electrode. This migration effectively separates the solution into a desalinated (dilute) stream and a concentrated (brine) stream.
Common applications include seawater desalination, table salt production, food and pharmaceutical processing (such as whey demineralization), regeneration of surface treatment solutions, and industrial wastewater treatment.
Reliable DC power is critical for driving this ion migration efficiently. Matsusada Precision offers high-performance DC power supplies designed to provide the stable voltage and current control required for industrial and research electrodialysis systems.
