As the availability of clean, potable water
becomes an increasingly urgent issue in many parts of the world,
researchers are searching for new ways to treat salty, brackish or
contaminated water to make it usable. Now a team at MIT has come up with
an innovative approach that, unlike most traditional desalination
systems, does not separate ions or water molecules with filters, which
can become clogged, or boiling, which consumes great amounts of energy.
Instead, the system uses an electrically driven shockwave within a stream of flowing water
, which pushes salty water to one side of the flow and fresh water to the other, allowing easy separation of the two streams.
