Research description
Capacitive Deionization- A novel desalination technology
Capacitive deionization (CDI) is a water desalination technology based on applying an electrical potential difference between two oppositely placed porous electrodes separated by a spacer compartment that allows solution to flow through (Fig.1). Ions are removed from the aqueous solution and are stored on the internal surface areas
inside of the porous electrodes, resulting in an effluent product stream with a reduced ion concentration.[1]
The assignment will be carried out at Wetsus where two setups in perfect order are available, and the student will work closely with PhD students on CDI experimentally and theoretically.
