Indigenous technology to convert sea water to drinking water
Desalination plants could solve drinking water scarcity in major cities of India
The minister of Earth Sciences, Dr Jitendra Singh, informed the Parliament that India has developed indigenous technology to convert sea water to potable water, and a successful trial has been conducted in Lakshadweep.
Three desalination plants based on the Low Temperature Thermal Desalination (LTTD) technology have been developed and demonstrated in Lakshadweep. The capacity of each of these LTTD plants is one lakh litre of potable water per day.
The LTTD technology is suitable for Lakshadweep islands because the required temperature difference of about 15⁰C between sea surface water and deep-sea water is found there.
Six more LTTD plants are likely to come up in the islands at Amini, Androth, Chetlet, Kadmat, Kalpeni and Kiltan with a capacity of 1.5 lakhs litres/day.
The total cost of the six LTTD plants in Lakshadweep islands will be around Rs.187.75 crore.
