“…Many researchers have contributed to enhancing solar still performance by the modifying design of the stills, varying the depth of basin water, , Tarawneh et al 2007, introducing external attachments like flat plate collector (Negi et al 2021, Subramanian et al 2020, Madiouli et al 2019, evacuated collector, different types of wick materials, the inclination of wicks (Fayaz et al 2022), using heat storage mediums and by introducing Nanoparticles (Negi et al 2020) to increase the productivity of the solar stills.…”

Solar still is the emerging technique to distilled water at places where there is a huge scarcity of drinking water. The current investigation deals with the productivity enhancement of distilled yield of conventional solar still (CSS) to obtain decontaminated fresh water. Experiments were conducted by modifying CSS for five different cases viz: (a). Conventional solar still without the wick, (b). Conventional solar still with the tilted wick at 15˚, 30˚, and 45˚ (c). Black painted basin conventional solar still (BPBCSS) with the tilted wick at 30˚. All experiments were performed on the month of March for approximate same climatic condition. From the preliminary investigation, the flow rate of basin water on the wick was kept fixat 0.2g/m2.secin such a way that the wick remained completely wet. The overall daily productivity of the caseswas found to be 3.802kg/m2, 3.925kg/m2, 4.25kg/m2,4.102kg/m2, and 4.372 kg/m2 for CSS without the wick, CSS with the tilted wick at 15˚, CSS with the tilted wick at 30˚, CSS with the tilted wick at 45˚, and BPBCSS with the tilted wick at 30˚ respectively. For BPCSS, the cost of the obtained yield distillate was found to be ₹1.38 per Liter, making it more affordable than CSS.

“…For instance, (Fayaz et al 2022), performed an experiment on solar still by introducing the tilted Khes cloth wick inside the basin at different angles. The best optimum productivity was found according to the latitude of the location at 30° tilted wick inclination.…”

The current paper evaluated experimentally an innovative sun tracking concentrated solar still under Egyptian climatic conditions during the summer of 2022. The proposed system consists of a 120-cm-diameter parabolic reflector mirror that tracks the sun using a dual axis tracking system, a cylindrical solar still with a volume of 3.7 L positioned in its focal point, and a concentration ratio of 12.5. The performance of the concentrated solar still was investigated in the context of two critical parameters. First, three feed water salinity (17, 27, 37) ppt samples were evaluated, followed by four percentages of saline water filling ratio (26.5, 39.8, 53.1, 66.3)%. Increasing the salinity of the feed water had no effect on solar still productivity, but increasing the saline water filling ratio did. The daily cumulative productivity of the system was 6 kg/m2 with an optimal filling ratio of 53.1%, a daily efficiency of 42.88%, and an average cost of freshwater production of 0.0489 $/L. The proposed system also had the highest instantaneous efficiency of 61.77% and the highest distilled water productivity rate of 0.941 kg/h m2.
