Electrodialysis

Electrodialysis desalinates water by using an electric field and ion-selective membranes to remove ions from saline water. Our group has explored several aspects of electrodialysis (ED): monovalent selective ED, to tailor brackish water for irrigation use; high salinity ED, for brine concentration and salt production; reconfiguration and balancing of ED cycles to raise energy efficiency; and hybrids of ED and RO for drinking water production.
