The document presents an experimental study on the performance enhancement of a galvanized iron (GI) basin passive solar still using horizontal and vertical meshes to increase distillate output. The research found that the vertical mesh significantly improved average distillate output by about 1000 ml per day, enhancing efficiency by 13%, while the horizontal mesh provided a more modest increase. These findings suggest that integrating meshes into solar stills is a cost-effective solution for improving water purification in arid regions.
