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.

This model example illustrates applications of this type that would nominally be built using the following products:
