Experimental study of a single slope solar still in Jordan

Abstract EN

The performance of a single slope solar still using different operational parameters was studied experimentally.

The increase in still productivity to about 33% was achieved when the wind speed increases by 50%, this due to the increase in temperature differences between the still cover and water.

The ambient conditions were found to have direct effect on the productivity of the still.

The study also showed that the daily production of still can be increased by reducing the depth and salinity of water in the basin.

It can be concluded that high salinity will create a sharp density gradients which can lead to stratification of different concentrations of salinity, creating trapping energy and preventing convection and reducing the productivity by 22%. Distilled water by solar stills can be one of the options for providing fresh water (some treatment required) for desert regions communities.
