Abstract

This paper presents an experimental study of performance of water stirring solar still. The Conventional Solar Still (CSS) has been modified, developed and tested to enhance the performance by using water stirring method. This modification was performed by fixing a mechanical wiper on the bottom of still basin. The experimental results on the modified solar still were analyzed and compared with that of conventional solar still (CSS) that has the same basin area, dimensions, water depth and operating conditions. Results showed that, the accumulated productivity from the water stirring solar still (WSSS) ranges from 3.27 to 3.82 L/m2 per day at water depth of 2 cm. The corresponding values for (CSS) range from 3.0 to 3.5 L/m2 per day. The increasing in productivity for WSSS is about 9.14 % more than that of the CSS.
