Using Shock Waves to Separate Salty Water From Fresh

Using Shock Waves to Separate Salty Water From Fresh
Nov-14-15
A team from MIT has developed a way to desalinate water using shock waves, which could significantly reduce the amount of energy currently used to purify salt water.

The technology, called shock electrodialysis, forces a shock wave of electrical current that pushes the flowing, salty water through a porous, glass material and a sandwich of membranes or electrodes. As the current moves through the system, the salt water is separated into areas of salt depletion or salt enriched. And when the electrical current reaches a critical point, a shock wave is created that divides the flow of water by creating a “barrier” that separates the fresh water from the salty water.

I have some experience regarding this . I worked on a NRC grant -building a high flow oil water separator. This was built based on the theory of -'two linear flow separation'. Our research , conducted at the Technical University of Nova Scotia -'Vessel research department and published for Imperial Oil, may apply here. Who do I discuss this with.
