A single basin single slope solar still was designed and fabricated at the Department of Chemical Engineering, IET Lucknow. Its performance was assessed in terms of the�yield of potable water. The effect of various climatic parameters was also studied. Al2O3 nanofluid was used to enhance the�yield of the solar still. In the presence of nanofluid, the total yield of the solar still improved by 16.6%. Its economic feasibility was analyzed and reported. The portability of the�small size of solar stills, its�better economics, easy fabrication, and good performance make them very useful for industrial as well as�household purposes. � The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.enDrinking waterNanofluidSDGSolar stillWater safetyArticle10.1007/s11356-024-33364-0
