Abstract: The aims of this research to present the possibility of using simple solar still to distillation of saline water in the northern areas of Iraq as well as to verify the reliability of research results published in the past to reach the standard adopted in determining the operational variables which affecting on the performance of solar still A series of tests to demonstrate the effect of the thickness of water in the basin on the productivity of solar still, the study showed productivity distilled rely mainly on the thick layer of water and it was also noted that the presence of local wind reduces the performance of solar still, but slightly. The presence of dye in the water was reduced the productivity of still and therefore, this option is not desirable to reach an improvement in the still productivity, except in the case of the use of special pigments to absorb large quantities of solar radiation, which imported materials and increase the cost of distillation. It also increased the salinity of the water in the basin of still leading to reduction in productivity and this reduction increased with the increased concentration of salt.
