Necessity is indeed the mother of invention. If it wasn’t for the drought that hit 13 states in India, this new way of converting sea water to potable water may not have been devised by Indian scientists. This new filtration process produces 6.3 million liters of potable water a day, converting sea water to potable water.

Water from the sea is being processed by the pilot plant at Tamil Nadu’s Kalpakkam, built by scientists of Bhabha Atomic Research Center (BARC). They use waste steam from a nuclear reactor to purify the seawater. The center also developed membranes to filter uranium and arsenic from groundwater.

Devices like a bicycle pedal with a water purifier installed and a household water purifier using thin membranes and special filters were also invented by the group. Both turn contaminated water into potable water.

KN Vyas, Director of BARC, said that other plants have been built in Punjab, West Bengal and Rajasthan to cater to the water needs of the people.
