AKIPRESS.COM - As 13 states struggle with drought, scientists in a corner of India have devised a way to make potable water - 6.3 million litres of it every day - from sea water. They have also developed certain filtration methods that ensure groundwater containing arsenic and uranium are safe to drink, reports NDTV.

The pilot plant at Tamil Nadu's Kalpakkam, built by scientists of Bhabha Atomic Research Centre uses waste steam from a nuclear reactor to purify the seawater. Its capacity is 6.3 million litres every day.

Currently, the fresh water is being used at the Kudankulam nuclear reactor. But this reporter tasted the purified water - it tasted like fresh water, not saline at all.

Several such plants have been installed in Punjab, as well as West Bengal, Rajasthan, said KN Vyas, Director, Bhabha Atomic Research Center (BARC), Mumbai.

"Besides, BARC has developed several membranes, by which, at a very small cost, groundwater contaminated by uranium or arsenic can be purified and make fit for drinking," Dr Vyas added.

On his recent visit to BARC, Prime Minister Narendra Modi had pedalled a bicycle that had a water purifier installed on it. It turns dirty contaminated water into potable water. Turning the pedals produces the energy the purifier needs.
