Description Not Available
Solar desalination device is very much useful in rural arid areas which are deprived of potable water and only saline water is available. The device is very cost effective can provide 8 to 10 litres of distilled water per day on clear sunny days. The solar still can be successfully used for desalination of saline water in rural areas for meeting requirement of potable water. The distillate output of solar still can be mixed with the available saline water in appropriate proportion to make it drinkable. In fact as much as 20 litres/day of potable water (150 ppm
TDS) can be made available in a day from raw water containing 300 ppm TDS by improved solar still. The use of solar desalination device would help in conservation of conventional fuels, such as firewood, cow dung cake and agricultural waste in rural areas of India. Conservation of firewood helps in preserving the ecosystems and cow dung cake could be used as fertilizer, which could help increase the agricultural production. Moreover, the use of this device would result in the reduction of the release of CO2 to the environment. The solar desalination unit will overcome the problem of corrosion associated with metallic solar still. In addition, there is a wide scale adoption of distilled water in dispensaries, laboratories, batteries etc.
