With the rising population and
continuous depletion of our natural resources, it has become very tough for
everyone to meet their basic needs of food and water. Also, at the rate with
which the water-stressed area continues to rise, we soon will be facing a huge
water crisis. This chapter specifically talks about India and its potential to
make a switch from conventional methods of water usage and switch to a
renewable energy-based water desalination unit. This chapter presents an elaborate
analysis of the Indian peninsular region and
talks about the major cities’ comparative performance in the basic design of the
solar humidificationdehumidification desalination
unit. It can be concluded that the southern-most area has a very large
potential for setting up an economically feasible desalination unit. Various
parameters are discussed, like humidity ratio, outgoing airstream temperature,
and mass rate of evaporated water. As Chennai has the best performance for the
particular unit for most of the year, with productivity reaching 44 kg/day, the
least favorable site seems to be Puri in Odisha, where productivity remains
less and constant at a maximum of 34 kg/day during summers.
