Abstract
Water is very limited in the arid regions like the Middle East, South Asia and countries where water is in polluted state like India. Due to impure drinking water more than 5 million people die per year according to WHO report. So all these factors indicates that there is need to develop or identify a technique to produce pure water. In this experiment, a solar still is designed and fabricated to produce distilled water from atmospheric air and an attempt is done to optimize the areas of collector and basin. In the designing of solar still box, the area of collector and basin are kept as 0.426 m2 and 0.372 m2 respectively. The average height gap between material basin and collector is designed to be 0.28 m and inclination given to the collector glasses is 30. Experiments were performed for the production of water considering different area of basin and the collector area is completely considered to obtain maximum radiation. Experimental results shown that the maximum water produced when the basin area is considered 80% of the total area (0.296 m2
of 0.372 m2 ) and collector area is 100% (0.426 m 2 ). The maximum water produced in a day was 168 ml/kg of desiccant material.
