BARC Scientists Make Sea Water Potable
May 21, 2016

As states across India grapple with the severe water shortage crisis, scientists at the Bhabha Atomic Research Centre (BARC) have come up with a solution that might keep the crisis from worsening—desalination of seawater.

Kalpakkam in Tamil Nadu is home to the pilot desalination plant, built by scientists of BARC. Using waste steam from the nuclear reactor, the plant is able to desalinate and purify seawater, making it fit for consumption.

  • They have also developed certain filtration methods that ensure groundwater containing arsenic and uranium are safe to drink.

  • The pilot plant at Tamil Nadu's Kalpakkam, built by scientists of Bhabha Atomic Research Centre use waste steam from a nuclear reactor to purify the seawater.

  • Currently, the fresh water is being used at the Kudankulam nuclear reactor. But the purified water is similar like fresh water, not saline at all.

  • Several such plants have been installed in Punjab, as well as West Bengal, Rajasthan.

  • BARC has also developed several membranes, by which, at a very small cost, groundwater contaminated by uranium or arsenic can be purified and make fit for drinking.

  • BARC also invented a pedalled 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.

The nuclear scientists have also made several household water purifiers that are being marketed all over drought-hit Marathwada. Some these use thin membranes and special filters to separate the contaminants.

BARC is a premier multi-disciplinary Nuclear Research Centre of India having excellent infrastructure for advanced Research and Development with expertise covering the entire spectrum of Nuclear Science & Engineering and related areas.
