Producing freshwater from brackish water could be cheaper and easier than previously thought, according to researchers who have developed a new technique for desalination. The process, which is a refinement of a well-known method called capacitive deionisation, could treat large volumes of water in a continuous ‘merry-go-round’ of carbon electrodes.
Likun Pan, a physicist at the East China Normal University in Shanghai who was not involved with the research, calls the technique a ‘radical departure’ for capacitive deionisation, the working principle of which dates back to the 1960s. ‘This [study] will be followed up by many groups in the world, I am sure, as it is so simple to do it in this way,’ he says.
