Nanoparticle Technology for Water Purification Contact Solution Provider

Solution Overview & Benefits

Professor Pradeep's group found that noble metal nanoparticles can completely degrade halocarbons into amorphous carbon and metal halides. This discovery has lead to world’s first nanotechnology based filter for pesticide removal. His group developed several technologies to remove contaminants from drinking water. Combining several such materials, an all-inclusive affordable drinking water purifier has been developed.

The water purification system uses nanotechnology to remove bacteria, viruses and other contaminants by filtering water through a specially crafted mixture of nanoparticles.

History & Development

This technology is undergoing field trials now.

The device, which is currently being tested in communities in India, could offer an affordable way to provide small families with at least 10 liters (2.6 gallons) of safe drinking water per day.
