“…The developed countries have found a way to solve this dilemma, which is the use of electric energy to desalinate sea water, but the third world countries are still struggling to provide for their peoples' drinking water needs. Researchers have worked to develop different ideas and models to solve the problem of lack of safe drinking water in remote and isolated areas (Kabeel et al, 2018a Singh et al (2020) concluded that the advancement of desalination puri cation innovations relied primarily on the highest quality of solar energy. Its progress may be interrupted by the dependence on technical aspects of the heat transfer properties.…”

This study is intended to comparative and analyze the operational performances of the conventional hemispherical solar still (CHSS), hemispherical solar still with glass cover cooling (HSS-C), and hemispherical solar still with CuO-water based nanofluid (HSS-N). To Obtain the best modifications that achieve the highest productivity with the lower inexpensive. The conventional hemispherical still (CHSS) was utilized as the reference case to investigate the best modification. In the first modification, CuO nanoparticles with three different concentrations (0.1, 0.2, and 0.3%) were added to the basin water, to increase the intensity of absorbed solar energy, improve the thermal properties of basin fluid, and then increase the rate of vapor generation inside the distillation basin. In the second modification, water film glass cooling technology with three different flow rates (1.5, 2, and 2.5 L/h) was utilized to increase the water vapor condensation rate. The experiments test of the three distillers (CHSS, HSS-N, and HSS-C) was conducted at the same weather conditions at 1 cm basin fluid depth. The average daily accumulative yield of CHSS is 3.85 L/m2/day, while the daily accumulative yield of HSS-N increases to 5.75, 6.40, and 6.80 L/m2/day with improvement 49.3, 66.2, and 76.6% at volume fraction 0.1, 0.2, and 0.3%, respectively. Also, the daily accumulative yield of HSS-C increases to 4.9, 5.35, and 5.7 L/m2/day with improvements of 27.3, 39, and 48% at water film flow rates of 1.5, 2, and 2.5 L/h, respectively. The cost of distilled water produced from CHSS is 0.0106 $/L, while the utilization of HSS-C (2.5 L/h) and HSS-N (0.3%) reduces the cost of distilled water to 0.0072 and 0.0066 $/L, respectively. Based on accumulative yield and economic analyzes, it is recommended that utilized the modified HSS-N (0.3% volume fraction) to achieving the highest accumulative yield and the lowest price of the produced distilled water.

This manuscript aims to study the experimental analysis of solar still with sandbags as energy storage materials. To achieve this idea, 25 bags filled with El Oued sand was fixed inside a square basin vertically and distributed regularly, this is called the modified solar still with sandbags (MSS-SB). The sand used in this study is very effective than many store mediums considered within many previous works such as glass balls, sponges, phosphate, yellow sand, black sand, and black gravel. This fact is due to its components characterized by high thermal conductivity. By using the Fourier-transform infrared spectroscopy, X-ray diffraction, and X-ray fluorescence, it has been confirmed that the chemical properties of El Oued sand are composed mainly by 97.6% quartz (SiO 2) and 0.56% calcite (CaCO 3) and very low concentrations of some other oxides. To obtain the influences of the sandbags utilized in this study, the performance of MSS-SB and traditional solar still (TSS) was tested at the same climatic conditions of the southeast of Algeria throughout 24 hours. Experimental results revealed that the overall cumulative distillate yield of TSS reached 3.76 L/m 2 /d, while for utilization the sandbags for MSS-SB increase the cumulative distillate yield to 5.06 L/m 2 /d, representing 34.57% Abbreviations: MSS-SB, modified solar still with sandbags; TSS, traditional solar still. improvement in cumulative distillate yield. Also, the daily efficiency of TSS 33.1%, while for utilization the sandbags for MSS-SB increases the daily efficiency to 44.63%, representing 34.83% improvement in daily efficiency.

Also, the use of this distilled water in all industrial developments, especially medical, became widespread. Many researchers are working on technologies to improve the yield of drinking water. The use of solar energy is the most common technology. 1-5 The use of single slope distillate is the traditional method of obtaining drinking water by using solar energy to heat the sink water, causing it to vaporize and then condense it through the glass cover. 6-10 Several previous studies have been conducted, all of which aim to improve the performance of solar stills by making adjustments to the design of stills, 11-15 use the nanofluids, 16 use the fins, 17-19 use the PCM, 20-23 and use the hybrid storage materials. 24-26 Energy efficiency was analyzed from several systems that used absorbent materials such as glass balls, black gravel, dyes, rubber, wicks, sand, and saw dust, as thermal storage materials. In previous studies, Samuel et al 27 experimentally used the encapsulation technique in one solar slope still to store thermal energy. The researchers concluded that this technology improved the yield by 2.5 times the traditional solar still (TSS). Badran 28 found that adding spong...

In this current study, a single basin solar still (SBSS) was explored in the climatic state of Patan (23.84° N, 72.12° E) India over March 2019. The SBSS was examined with the use of waste brick magnesia (WBM) for the same amount of water (10 L). For experimentation, three same‐sized SBSS were taken with 3 and 6 kg WBM and without storage materials. It was found that a daytime yield for SBSS of 2.27 L without storage materials was obtained; and this was reduced for SBSS with 3 and 6 kg WBM to 1.96 and 1.75 L, respectively. It has also been noticed that the yield of SBSS during off‐sunshine hours due to the energy storage capacity increased with WBM but the combined (daytime + off‐sunshine hours) yield was found reduced with an increment in a mass of the WBM. It was found that the maximum instantaneous thermal efficiency of the SBSS without WBM, 3 and 6 kg WBM was 60.24%, 45.65%, and 54.26%, respectively. Overall thermal efficiency was also determined and obtained to be higher for SBSS without WBM as storage.
