Desalination in an Electrodialysis Cell
Application ID: 3849
Electrodialysis is a separation process for electrolytes based on the use of electric fields and ion selective membranes. Some common applications of the electrodialysis process are:
- Desalination of process streams, effluents, and drinking water
- pH regulation in order to remove acids from, for example, fruit juices and wines
- Electrowinning of precious metals
This tutorial demonstrates the basics of electrodialysis in a desalination cell that removes sodium chloride from a dilute water solution and into a more highly concentrated solution.
