In the backdrop of severe drought that has hit almost 13 states across India, scientists in Tamil Nadu have devised a new system that can make seawater potable and safe to drink. What is more important is that it will be able to produce 6.3 million litres of water every day.
The scientists have also inculcated certain filtration methods that will ensure groundwater containing arsenic and uranium is safe to drink.
The pilot plant has been set up by scientists of Bhabha Atomic Research Centre (BARC) at Kalpakkam in Tamil Nadu, where they use waste steam from a nuclear reactor to purify seawater. The water is desalinated and it tastes like fresh water.
According to NDTV, several plants have been set up in West Bengal, Punjab, Rajasthan, said KN Vyas, Director of BARC, Mumbai. Several membranes have also been developed by BARC that can produce purified drinking water out of groundwater contaminated by uranium or arsenic, at a meager cost.
These scientists have also made several household water purifiers that are being marketed all over the drought-hit areas of Marathwada, Maharashtra. These purifiers have thin membranes and special filters to separate contaminants.
We appreciate the brilliance of the scientists of BARC for coming up with a system like this. This discovery will be able to solve the problem of water crises that has affected millions of Indians.
