A parabolic concentrating solar thermal desalination device was designed, developed, and fabricated.
The surface area of the parabolic concentrator made of steel is 2.60 m and the projected area of the
disc is 1.50 m. The performance evaluation of the device during the summer and winter months of
the year 2019 in the hot arid climate of Jodhpur, India was carried out by measuring distillate output
per day. The maximum productivity of 6.5 L/d within 9 h in a day was measured with the maximum
average solar insolation of 745 W m–2 during May 2019 and 5.5 L/d in winter month December
2019. The maximum daily average efficiency of 34.2% in May and 32.3% in December was calculated
with a maximum hourly output of 0.85 L/h. The distillate output of solar desalination device is to
be mixed with the available saline water in appropriate proportion to make it drinkable. In fact, as
much as 20 L/d of a potable water (150–180 ppm TDS – total dissolved solids) can be made available
in a day from raw water containing 300 ppm TDS by a solar desalination device. The economic
evaluation of the parabolic concentrating solar thermal desalination device revealed that high value
of internal rate of return (74.6%) and low value of the payback period (1.45 y) make the unit very
cost-efficient. The economic attributes of the system revealed its economic viability. Therefore, this
solar desalination device can be successfully used for desalination of saline water in rural arid areas
for meeting requirement of potable water as per WHO guidelines for drinking water quality.
