CTET is engaged in the development and optimisation of a range of electrochemical processes for brackish water desalination, organic contaminant degradation and resource recovery including fixed and flow electrode membrane capacitive deionisation and fixed and flow electrode anodic oxidation.
When a voltage is applied across two electrodes, cations are attracted to the cathode and anions to the anode, resulting in the charged species being removed from solution. A novel CDI system driven by solar energy has been developed by UNSW to remove salts and other contaminants from water.
FCDI is a technology based on the formation of electrical double layers (EDLs) in charged suspensions of electrodes enabling capacitive energy storage with the minority charged constituents immobilized and selectively extracted from the saline water. UNSW and CTET are actively developing a series of FCDI technologies for recovery of resources (including ammonia and phosphorus) from wastewaters.
