Experimental studies on solar stills and their performance characteristics

Summary Demineralization of saline water, using different designs of solar stills, has been considered. The productivity and efficiency of these stills, were determined daily and for a whole year.To investigate the basic principles of the solar distillation process, meteorological measurements concerning the solar intensity the wind speed and the ambient air temperature were undertaken simultaneously together with the temperature measurements of the brine and the glass cover of one of the stills during its operation. The results obtained gave valuable information concerning the construction and design of solar stills.
