Around 13 states in the sub-continent have already been affected by severe drought. The sweet-water (potable) reserves are degrading day by day due to overuse of these resources and pollution . To prevent such decrease in water, a group of scientist from the state of Tamil Nadu has resorted for converting the salty sea-water into usable potable drinking water. Three-fourth of the world being covered with sea, this innovation is sure to be a boon for all the farmers suffering in the drought affected regions.
This scientist from Bhabha Atomic Research Centre (BARC) have developed a filtration process which is capable of converting groundwater with arsenic and other heavy meatls like uranium into water which can quench ever growing thirst. The new method implemented in a projevt is calculated to produce 6.3 million litres of water each day to fulfill the need of the people. The main plant is located at Kalapakkam in the state of Tamil Nadu. The plant is designed to use the wastes from the nuclear reactor to steer clear the saltiness present in sea water. The sea-water is hence cleaned and the water is desalinated to make it appropriate for drinking!
KN Vyas, from BARC is reported to say that many such plants will be set up across the sea belts of West Bengal, Punjab, Rajasthan and Maharashtra to make purified water available to these states. He further claimed that the membranes designed to purify underground water will also be setup and they will deliver water at a minimum cost. Special filters designed by this scientist with thin membranes are distributed among households of Marthawada in Maharashtra affected by drought, so that they can separate even the most miniscule contaminants from the water and hence make it fit for drinking!
