MIT develops new technology that shocks the salt out of water

MIT develops new technology that shocks the salt out of water

Martin Bazant, engineering and mathematics professor at MIT, and his team are happy to introduce “a fundamentally new and different separation system” that is comparable to conventional methods. The technique, called shock electrodialysis , does not rely on barriers to strain sodium particles from water. Instead, it uses a porous material – called a frit, made of small glass particles – with electrodes attached to the sides to apply an electrical current to the flow of water inside. Salt enriched and depleted water begin to separate. When the current is increased to a certain point, a shockwave creates a stark divide between the flows, which can be separated into different channels. The fresh water can then be collected for use.
