Turning Sea Water into Drinking Water

In the computer age, reboot stands for restart. But what
about deboot? It has nothing to do with footwear, either. DEBOOT is, actually,
an acronym for DEsign, Build, Own, Operate, Transfer. An example is a
desalination joint venture between Indian and Spanish companies. The desalinated
water is transferred to the Chennai Metropolitan Water Supply and Sewerage
Board.

Desalination is seen as a viable solution to the water scarcity
that Indians face in many cities. Earlier, the high cost of desalination made it
an unattractive option even in coastal cities that had easy access to sea water.
But this new plant “will supply 1000 liters drinking water for just $1 and could
well be a ‘template’ for other coastal Indian cities,” according to Swaminathan
Natarajan of the BBC.

So what changed?

As the news report
elaborated, since water purification occurs through filtering at high pressure
rather than high temperature, less energy is expended. It is commonly known as
advanced reverse osmosis. Also worth noting: India’s success in Low Temperature
Thermal Desalination (LTTD) can be attributed to NIOT. It stands for the
National Institute of Ocean Technology and is located in Chennai. The first LTTD
plant opened in 2005 on the island of Lakshadweep, India’s smallest union
territory, which is not too far from the Kerala coast.
