Experimental study of the enhancement parameters on a single slope solar still productivity

The performance of a single slope solar still using different operational parameters was studied experimentally. The still productivity increased up to 51% when combined enhancers such as asphalt basin liner and sprinkler have been applied to the still. Also the ambient conditions were found to have direct effect on the productivity of the still. The night production in the absence of solar radiation contributed to 16% of the daily output due to the differences in temperature between the cover and water, and the decrease of heat capacity. The study also showed that the daily production of still can be increased by reducing the depth of the water in the basin.

An experimental work has been conducted to predict the productivity of a single slope solar still using different operational parameters. The use of asphalt in the basin resulted in a significant improvement in still production for an increase of 29%. The sprinkler combination with the asphalt was more effective than the use of asphalt alone by another 22%. It can be concluded also that the ambient conditions (i.e. wind and temperature) have a direct effect on the still productivity. Also it is evident from the result that as the depth of water decreases the daily still output is increased.
