Performance Enhancement of Single Basin Single Slope Solar Still Using Absorbing Material

The simplicity of solar distillation makes it possible to have a sustainable solution for water purification in regions facing freshwater scarcity. This paper monitors the performance of a single basin single slope solar still coupled with different absorbing materials with the view to improving thermal energy absorption and hence water output. An experiment was made using black stones, charcoal powder, and sand as basin-lining materials. Results indicate a great daily yield improvement over that of a conventional still without absorbing materials.
