A WATER-saving cleaning system devised by Hampshire scientists has won a prestigious national award.

The revolutionary ultrasonic StarStream was recognised at the 2012 Institute of Chemical Engineers Awards for its potential to cut energy costs and reduce water use.

The system, invented by researchers at the University of Southampton, makes water more efficient for cleaning by creating tiny bubbles which automatically scrub surfaces.

It is the second major award for the team, who were given £250,000 towards its development last year by the Royal Society for scooping the Brian Mercer Award for Innovation.

Doctors Peter Birkin and Doug Offin, from the chemistry department, and Professor Tim Leighton from the Institute of Sound and Vibration Research, picked up the award in the Veolia Water Management and Supply category from TV presenter Colin Murray, beating firms including GlaxoSmithKline and Scottish Water.
