MUMBAI: There are 13 states that struggle with drought, and due to that fact, scientists in a corner of India have devised a way to make potable water. Namely, they can get 6.3 million liter of it every day from sea water. Isn’t that astounding?
Moreover, they also developed specific filtration methods that actually ensure groundwater containing arsenic and uranium are safe to drink.
At Tamil Nadu’s Kalpakkam the pilot plant was built by scientists of Bhabha Atomic Research Centre. They use waste steam from a nuclear reactor to purify the seawater. The capacity of this invention is 6.3 million liters every day.
At this point, the fresh water is being used at the Kudankulam nuclear reactor. Still, according to the reporter who tasted the purified water, it has the same taste as fresh water, not saline at all.
There are several such plants that are installed in Punjab, but also in West Bengal, Rajasthan, said KN Vyas, Director, Bhabha Atomic Research Center and Mumbai.
Dr Vyas says: “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”.
Prime Minister Narendra Modi on his recent visit to BARC, had pedalled a bicycle that had a water purifier installed on it. On this way, the dirty contaminated water turns into potable water. It is interesting that turning the pedals produces the energy the purifier needs.
In addition to that, the nuclear scientists have made several household water purifiers. These machines are being marketed all over drought – hit Marathwada. It is important to mention that some these use very thin membranes and special filters to separate the contaminants.
