Scientists in Tamil Nadu’s Kalpakkam pilot have devised a new method to turn sea water in drinkable water. Kalpakkam is a Bhabha Atomic Research Centre funded plant which has developed filtration methods. Reports suggest that there is no difference between the fresh and desalinated water. This water is being used in the Kudankulam plant currently by its staff.
The scientists have used steam from a nuclear reactor to cleanse the seawater upto a capacity of 6.3 million litres everyday. Considering the sad state of drought affliction, this innovation could be a major source of relief. Such purifying plants have been installed in Punjab, West Bengal and Rajasthan.
A household version has also been made for distribution in the specially hit Marathwada region. These units have thin membranes and special filters to separate the contaminants. The cost of these devices is very low.
PM Narendra Modi on his recent visit to BARC, pedalled a bicycle that converted contaminated water into potable water via a filter attached to the cycle. Turning the pedals produces the energy the purifier needs.
