As several states of India faced sever water shortage and drought, our scientists have devised a method to produce fresh water - 63 lakh litres of potable water every day - from sea water. In addition, they have also assured that groundwater which has arsenic and uranium is safe for human consumption.
The filter plant was set up at Tamil Nadu's Kalpakkam by scientists of the Bhabha Atomic Research Centre ( BARC) use waste steam from a nuclear reactor to filter the saline water.
"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," Dr Vyas added.
Good initiative
ReplyDeleteFiltering Salt water , does it mean desalination too ? Filtration, in conventional terminology does not ensure desalination. For that osmosis through appropriate membranes or more expensive distillation is the remedy . Solar energy can be used for inexpensive distillation .The report tells another story at Kalapakkam.Further the reported capacity of 63 lakhs litre per day is a doubtful figure. Any comment ?
