SOLAR WATER DISTILLATION

Abstract

In this work, Number of stepped type solar stills with varying depth of water and other design
parameters like thickness of glass cover, insulation thickness, condensing cover material, shape of the absorber surface,
absorbing material provided over the basin surface, angle of inclination of the still etc. being fixed have been selected for
experimentation. The depth of water provided in solar stills is 5 mm. Thus, as depth of water goes on increasing, the
distillate yield produced per unit area of absorber surface goes on decreasing. Also, an economic analysis was made.
