Solar desalination devices made of cement concrete hollow block, stone masonry, cement-concrete,
brick masonary and vermiculite-cement have been designed, developed and constructed. These are
basin type solar stills with absorber area 4.2 m2 of each device and the bottom is painted with epoxy
paint. The longer dimension of the device is in the east west direction so that it collects more solar
radiation. One 3.5 mm thick clear window glass is provided over it having 20° tilt from the horizontal
and two distillate channels are fixed for collection of distilled water. The performance evaluation of
the devices made of cement concrete hollow block, stone masonry, cement-concrete, brick masonary
and vermiculite-cement during winter and summer month were carried out by measuring distilled
water obtained per day. The average output of the device during summer month (May 2017) was
8065, 8117, 8230, 8340 and 8540 ml d–1 and in winter month (December 2017) was 7029, 7173, 7285, 7395
and 7595 ml d–1. The unit made of vermiculite-cement gave the higher yield due to better insulation
and reduced heat loss. The average efficiency was 24.61%, 28.21%, 28.55%, 29.54% and 30.25% respectively. 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 potable water (150 ppm
TDS) can be made available in a day from raw water containing 300 ppm TDS by a solar desalination
device. The economic evaluation of the vermiculite-cement type solar desalination device revealed
that high value of IRR (151 per cent) and low value of payback period (0.65y) 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.
