Question 103: Science and Technology
Where was the first desalination plant in India to produce one lakh litres freshwater per day based on low temperature thermal desalination principle commissioned?
AnswerThe answer is (a).
India's first low-temperature thermal desalination (LTTD) plant, making one lakh litres of fresh water a day, was commissioned at Kavaratti in Lakshadweep in 2005. It was developed by the National Institute of Ocean Technology (NIOT), Chennai. LTTD uses the temperature difference between warm surface sea water and cold deep sea water, so it suits islands with deep water close to the shore.
Why each option is right or wrong
- (a) Kavaratti in Lakshadweep has the plant.
- (b) Port Blair was not the site of the first such plant.
- (c) Mangalore was not the site of the first such plant.
- (d) Valsad was not the site of the first such plant.
