Desalination of water using double slope double basin solar still coupled with evacuated tubes

Abstract

Water temperature and glass temperature are the quantities which give productivity of a solar-still. This paper deals with a study done on a double-slop, double-basin solar-still directly connected with evacuated tubes, where in productivity is increased upon reduction of heat loss. Eight double-walled hard borosilicate glass tubes have been used. The experiments were conducted on the still only during sunlight hours from 9 am to 5 pm; and by using tap water as feed. Results obtained were plotted and laboratory results of chemical composition of water given as input and collected from the basin were found out.
