electrodialysis e·lec·tro·di·al·y·sis (ĭ-lěk'trō-dī-āl'ĭ-sĭs)
Dialysis at a rate increased by the application of an electric potential across the dialysis membrane, used especially to remove electrolytes from a colloidal suspension.
A process by which ionized materials dissolved in a liquid, such as the anions and cations of dissolved salts, are moved across a membrane by the application of an electric field, separating them from liquids or ions of opposite charge. Electrodialysis can be use for the desalinization of brackish water.
