Abstract

Availability of clean drinking water is becoming a major issue in the 21st century. The issue is increased because of decreasing water sources and increased population and related agriculture and industrial consumption requirement. There are different methods of cleaning the water but the world is changing to more environmentally friendly methods. Use of solar still is one of the methods which has lower carbon footprints. The present study conducted an experiment and compared the performance of use of four different type of materials including wiry sponge, black volcanic rocks, coated metallic, and uncoated metallic wiry sponge. The experiment continued for 1 week and the performance was monitored on hourly basis. The results show that among the four materials used in the solar still, the coated metallic material had the highest productivity level; followed by the black volcanic rocks.
