AHMEDABAD: City-based Institute for Plasma Research ( IPR ) has developed ‘wonder water’ that can kill E. coli, fungus and other microbes. What’s more, once dipped in this water, fruits and veggies like tomatoes and potatoes remain bright and fresh for a good 40 days!

IPR scientists have developed the Plasma Activated Water (PAW) system at its Facilitation Centre for Industrial Plasma Technologies (FCIPT) in Gandhinagar. The scientists say the system was developed over past few months where normal water, once treated with non-thermal plasma, turns into PAW, or wonder liquid.

On being tested for its potential uses, PAW was found to have excellent anti-microbial properties. Tests at Gujarat Environment Management Institute (GEMI) revealed that PAW eliminated all escherichia coli (E. coli) bacteria, found aplenty in human gut and sewerage water, in 30 minutes flat. Dr Natasha Khatri of GEMI said microbial tests on PAW were very encouraging.

“We found that PAW becomes more potent to kill bacteria at higher oxidation-reduction potential (ORP). For instance, PAW induced with ORP of 200 millivolt kills E. coli in 15-20 minutes. The same PAW with an ORP of a high 800 millivolt can eliminate E. coli in a matter of seconds,” said a senior FCIPT-IPR scientist.

PAW also can resolve problem of farmers, traders and housewives alike by being a miraculous preservative for veggies and fruits.

In the FCIPT journal, the APD head Dr S K Nema reported that tomatoes and potatoes washed once in PAW caused them to look and remain fresh for nearly 40 days at room temperature.
