Electromembrane Processes consist of those technologies that apply the electric potential gradient as the driving force of ion transport. They are increasingly important group of separation methods for removal of charged components from solutions such as for producing potable water from brackish water.
The main electromembrane processes are:
- Electrodeionization (EDI)
- Electrodialysis (ED)
- Electrodialysis reversal (EDR)
- Electrodialysis with bipolar membrane (EDBM)
- Capacitive deionization (CDI)
