Conversion of Sea Water into Potable Water
An eighteen lakh (18 lakh) litres per day capacity desalination plant operating on the Reverse Osmosis (RO) process has been setup, as part of Nuclear Desalination Demonstration Project (NDDP) at Kalpakkam, Tamil Nadu. Another plant, a Multi-Stage Flash (MSF) Desalination Plant with a capacity of forty five lakh (45 lakh) litres per day has also been setup at Kalpakkam as a part of NDDP. It is located adjacent to Madras Atomic Power Station (MAPS) and uses low pressure steam as energy input for MSF desalination plant. The hybrid MSF-RO plant is operated to produce distilled water for high end industrial applications and potable water for drinking and other applications.

The per litre cost of conversion of seawater into potable water by atomic energy varies between 5 & 10 paise depending on site conditions, end product quality and the technology in use.

The technology for setting up desalination plants is available with the Government in the Department of Atomic Energy for large scale conversion of sea water into potable water.

The above information was given by the Minister of State in the Ministry Personnel, Public Grievances & Pensions and in the Prime Minister’s Office, Shri V. Narayanasamy to the Parliament today.
