CDI low-energy desalination can supply remote communities

Professor Linda Zou, South Australian Water Centre for Water Management & Reuse, University of South Australia

There has been a lot of media fuss recently about the work at the Massachusetts Institute of Technology on using graphene sheets in membrane desalination. Equally important work is going on in Australia on using graphene sheets as electrodes for capacitive deionisation (CDI).

Supported by the National Centre for Excellence in Desalination, Professor Linda Zou has proved that CDI technology offers a viable alternative solution for brackish water treatment, especially in communities in remote areas where building a large and high-maintenance treatment plant is not practical.
