Indian scientists have found a way to make potable water from sea water – 6.3 million liter of it each day. This happens while 13 states have troubles with drought. Moreover, these scientists also developed certain filtration methods to guarantee groundwater containing arsenic and uranium is secure to drink.
The pilot plant is built at Tamil Nadu’s Kalpakkam by scientists of Bhabha ATOMIC Research Centre. The plant uses waste stream from a nuclear reactor in order to clean the seawater. The capacity of the plant is 6.3 million liter on a daily basis.
The Kudankulam nuclear reactor uses the fresh water at the moment. The purified water tastes like fresh water and it is not saline at all.
Such plants have been installed in Punjab, West Bengal, and Rajasthan.
BARC has developed several membranes by which at a small cost contaminated groundwater can be purified and then drinkable.
