“…The productivity of the SSSS with CuO-NCAPs was 2.9 L/m 2 /day, while the cost of the water distilled was USD 0.0077/L. Sharma et al [32] evaluated the effect of copper fins on the freshwater production within a pyramid solar still. The experiment featured two sets of absorber plates-one with copper fins.…”

All living organisms depend on water for their survival. Therefore, sufficient water availability is necessary for health. During the last few years, considerable progress has been made in the production of clean drinking water—particularly in the desalination industry. Various methods have been explored to boost the productivity of solar stills. The present review focuses on recent enhancement techniques aimed at boosting their performance—particularly those incorporating non-metallic nanofluids into the base fluid. The nanomaterials examined in this review include Al2O3, CuO, ZnO, and TiO2. Several studies adding Al2O3 in a solar-still desalination system resulted in an increase in distillate yield, better efficiency, reduced energy consumption, reduced thermal loss, and better productivity. The incorporation of CuO in a solar-still desalination system led to major improvements in performance. These included enhanced daily efficiency, better productivity, improved production of freshwater, and higher energy and exergy efficiency. The incorporation of TiO2 in a solar-still desalination system resulted in increased productivity, better thermal conductivity, better thermal efficiency, higher daily distillate output, and high levels of water temperature. It was also evident that the incorporation of ZnO in a solar-still desalination system resulted in a substantial increase in the output of clean water and occasioned improvements in productivity and overall efficiency. Together, these findings demonstrate the potential of these nanomaterials to significantly enhance the performance of solar-still desalination systems. Other nanomaterials that are yet to gain increased use, such as SiO2 and SnO2, have also been discussed. The collective results in this paper demonstrate the potential of nanofluids to enhance the performance and effectiveness of solar-still desalination systems. This review provides conclusive evidence of the positive effects of different nanofluids on the yield, productivity, energy, and efficiency of diverse types of solar stills, offering promising advancements in the sustainable production of water.

Purpose This study aims to investigate the effect of porous material (clay pots) and it is facing on the productivity performance of a pyramid type solar still. The clay pots are placed in the basin facing up and facing down. The numbers of clay pots considered were 9 and 25, and its performance was compared with normal (0 clay pots) solar still. Design/methodology/approach The pyramid solar water distillation system has been designed, fabricated and tested under the actual environmental conditions of Kanchikacherla (16.6834 0N, 80.3904 0E), Andhra Pradesh, India. The solar still is used to produce the fresh water and hot water simultaneously from the brackish (i.e. containing dissolved salts) feed water for domestic applications. From open literature, it was established that the rate of evaporation is higher when the flowing water is held for a longer duration on the black color absorber plate, thereby leading to an increase in productivity of freshwater. Therefore, the pyramid solar still has been tested for smooth absorber plate and the absorber plate with porous heat storage material. Findings The porous material increases the production rate of freshwater compared to a base plate. However, the pyramid still with clay pots has higher productivity at a lower temperature because of the porosity effect. Originality/value The total dissolved solids, electrical conductivity and pH of the distilled water and the saline water have also been measured and compared.
