Electrodialysis is a membrane-based separation process that uses an electric field to drive the movement of ions through selective ion-exchange membranes, allowing for the desalination of water and the recovery of valuable resources. This technique is particularly effective for treating brackish water and wastewater, making it a significant method in modern water treatment. By using cation and anion exchange membranes, electrodialysis can efficiently separate salts from water, making it an important technology in both water purification and resource recovery.
congrats on reading the definition of Electrodialysis. now let's actually learn it.
