The present work aims at improving the performance of a glass solar still using different new absorbers (enameled sheet metal, blackened sponge, blackened gravel, clay, charcoal and quicklime) as sensible heat storage systems under the desert climatic conditions of Adrar. Most of the solar stills studied up to now are made of sheet metal with a black coating. The main disadvantage of these systems lies in their high corrosion and water contamination by the rust of the metal used and some toxic elements. Two solar stills were designed, constructed and tested in this study in order to compare the efficiencies of the different solar desalination systems. The first one is a glass solar still with sensible heat storage materials and the second one is a conventional solar still. The solar still studied was fabricated from cheap locally available glass and healthy materials. The hourly water and glass temperatures, productivity, and efficiency of the still were measured and evaluated experimentally. Moreover, a comparison between the different materials used as absorbers was carried out as well. From the results, it was observed that the system could produce 5.6 l/m²/day of fresh water; it was also found that metal was the best absorber as it exhibited the highest productivity as compared with the other absorbers. However, the maximum volume produced by the conventional solar still was only 4.88 l/m² per day. The lowest productivity, of about 1.6 l / m² /day, was observed with quicklime. In addition, physical analysis of distillate output shows that the quality of water produced is better.

“…This introduction in the previous studies section reviews some of the different thermal storage materials that several researchers have tried to improve a distillation yield from solar distillation. Nasri et al, (2019) examined in uences of various absorbers (polyethylene, gravel, and sand) on classical distiller. They concluded that the gravel is a best absorber.…”

The present work aims to obtain the optimized construction of marble pieces that achieves the highest hemispherical solar distiller’s performance. To achieve this idea, four different marble pieces (black marble pieces, green marble pieces, red marble pieces, and white marble pieces) were tested to obtain the optimal construction of the marble that achieves the highest hemispherical solar distiller performance. The marble pieces were placed on a basin of hemispherical distillers which represent absorber materials, as well as the sensible thermal storage materials. This was done by design and constructed three hemispherical distillers, first represent the classical hemispherical distiller (CHD) which represent the reference case, but the marble pieces were placed inside the basin of the second and third distiller. The experimentation tested were conducted on two cases; in the first case we tested two types of marble pieces (black and green marble pieces) by placed them in the second and third distiller (hemispherical distiller with black marble pieces (HSD-BMP) and hemispherical distiller with green marble pieces (HSD-GMP)). In the second case we tested the other two types of marble pieces (red and white marble pieces) by placed them in the second and third distiller (hemispherical distiller with red marble pieces (HSD-RMP) and hemispherical distiller with white marble pieces (HSD-WMP)). The results showed that utilization of red marble pieces (HSD-RMP) represents a good choice which improved the accumulative productivity to 7.75 l/m2 day compared to 4.8 l/m2day that achieved by the CHD with an improvement of 61.46%. The accumulative thermal efficiency of CHD reached 39.25%, while the utilization of red marble pieces (HSD-RMP) improved the accumulative thermal efficiency to 62.98%. Also, the use of red marble pieces reduced the distillate cost by 35.6% compared to the reference distiller.

In this paper, an experimental study of the conventional solar still (CSS), the conventional solar still with glass cooling (CSSGC), the conventional solar still with basin heating (CSSBH), and the conventional solar still with glass cooling and basin heating (CSSGCBH) was carried out on the basis of the distilled water production, the energy efficiency (EnE), the exergy efficiency (ExE), and economic analysis. The CSSGC and CSSBH contain Peltier modules for cooling the glass and heating the basin. The evaporative heat transfer coefficient for all the experimental stills was calculated. The values of daily distilled water production from the CSSGCBH, CSSBH, CSSGC, and CSS were 4.56, 3.79, 2.49, and 1.89 kg/m 2 , respectively. The daily distilled yield of the CSSBH and CSSGCBH were increased by 58.55% and 50.13%, respectively, as compared with the CSS. Moreover, the daily EnE and ExE of the CSSGCBH were 27.03% and 3.5%, respectively, whereas the EnE and ExE of the CSS were 10.88% and 1.3%, respectively. Furthermore, the cost of distilled water Abbreviations: CSS, conventional solar still; CSSBH, conventional solar still with basin heating; CSSGC, conventional solar still with glass cooling; CSSGCBH, conventional solar still with glass cooling and basin heating; EHTC, evaporative heat transfer coefficient; EnE, energy efficiency; ExE, exergy efficiency; T w − T g , temperature difference between the water and glass cover.
