Enhancing Solar Still Efficiency: Optimal Water Depth and Wire Mesh-Pebble

Table 4 illustrates the effect of a 2 cm depth of saline water on the production of distilled water over the course of the day. [...] The results reveal that the depth of the saline water has a major effect on the solar still’s performance, indicating how varying depths affect temperature fluctuations and, as a result, the production of distilled water throughout the day. [...] These results indicate the effectiveness of the modifications, particularly the combination of wire mesh and pebbles, in enhancing the overall water yield compared to the conventional solar still. [...] The comparison involves the conventional solar still, the modified solar still using wire mesh, and the modified solar still using both wire mesh and pebbles. [...] The peak production occurs in the afternoon around 14:00 hours, with the maximum amount of distillate recorded at approximately 350 ml for the conventional still, 410 ml for the modified solar still with wire mesh, and 425 ml for the modified solar still with wire mesh and pebbles.
