Is there any technology available in the world for converting sea water into drinking water and if it is available in the world, is it avaiblable in India ?

If available is it costlier or not ?

It is very expensive to process sea water for fresh water generation. Technology is simple De-Salination of water but very very expensive for large scale processing like supplying water to a city. UAE is using this tech.

In Jamnagar, Reliance refinery is converting sea water to potable water by Flash Evaporation. It needs energy.

Reverse Osmosis is another technique, which uses membrane technology. Needs lots of pumping energy. Most of Middle east and offshore oil platform as well as ships use them to produce potable water.
Ofcourse nothing to beat natural rain water where nature does the job.

I do agree that desalination process consumes lots of energy and is expensive, but we have to get our priorities right. India is blessed with a large coastline and we got to make use of that resource. We have money to spend on luxury goods but no one is willing to pay for water. Let us get our priorities right, we spend lot of money to drink mineral water, I am sure people will pay for desalinated water. it is just a question of working the economics out and setting a tariff that is affordable and ensuring that there are no leakages in the system(no T&D losses like power theft).
