Electrochemical and Advanced Oxidation Processes

CTET is developing innovative technologies based on both the use of electrochemical principles and so-called advanced oxidation processes (AOPs) where AOPs involve the generation of powerful oxidants such as hydroxyl radicals and high valent metal species.

  • Capacitive Deionization (CDI):

When a voltage is applied across two electrodes, cations are attracted to the cathode and anions to the anode, resulting in the salt ions being removed from the solution. A novel system driven by solar energy has been developed by UNSW to remove salts and other contaminants from water.

  •  Flow-electrode capacitive deionization (FCDI):

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 (ammonia, lithium, phosphorus) from waste

> Advanced Oxidation Processes (AOPs)

AOPs involve the generation of a reactive oxidant (usually hydroxyl radicals), capable of inducing oxidation of organic contaminants. The strong oxidant is produced using one or more primary oxidants (O3, H2O2) and/or energy source (UV light) and/or catalysts (TiO2, Fe2+).

Ultilising the research expertise at UNSW Sydney, UNSW and CTET have developed a suite of AOP technologies that can reduce the organics with low biodegradability and high toxicity from different wastewaters.
