1. a process that uses electric current to separate ions from a solution by passing them through semipermeable membranes, used to desalt water or purify solutions.
Usage: technical; chemistry and engineering

Examples

• Electrodialysis is commonly used to remove salt from brackish water in coastal regions.
• The desalination plant employs electrodialysis to produce fresh water from seawater.
• Electrodialysis requires less energy than reverse osmosis for certain applications.
• Industrial facilities use electrodialysis to purify whey in dairy processing.
• The electrodialysis unit separates cations and anions using alternating electric fields.
