London, July 16 : American scientists have devised a novel technique to purify water, which is based on a process called the “particle-exclusion phenomenon” that was discovered by University of Washington researchers in 2003.

Gerald Pollack and his colleagues had discovered that particles dissolved in water naturally move away from a hydrophilic (water-loving) surface, leaving pure water behind.

He says that the particles can move up to several tenths of a millimetre, much further than predicted by conventional theories.

The researcher believes that the phenomenon is caused by water molecules forming into a liquid-crystal-like array that sits on the hydrophilic surface.
