More On NIOT's Desalination Plant

Some clarifications on the new desalination plant unveiled by the National Institute of Ocean Technology.

Sagar Shakti, NIOT's recently unveiled barge-mounted desalination plant, produces one million liters a day at about 6 paise per liter. This however is just an experimental plant. To go commercial NIOT will partner with a private company. Director S. Kathiroli estimates that a plant with 25 million liters per day capacity should be able to produce water at just 3 paise per liter (which is on par with international costs on much bigger plants).

Kathiroli also goes on to explain how this technology has high sustainability standards.

The process is a controlled recreation of water cycle that brings about rain. It involves flash evaporation of warm surface seawater and condensation of the vapours with cold deep-sea water.

The method is environment- friendly, and simple enough not requiring too much skilled manpower.

"There is no brine or anything formed. Secondly, we bring deep sea cold water, which is rich in nutrients. So wherever the plant is, at least 10- 20 kilometres around, you will see that Mari culture will grow quite a lot," Kathiroli said. >> Link
