Access to drinking water in many parts of the globe is shrinking over the years and much of the water resources are polluted or unpurified. North Africa is facing a huge water shortage due to drought and climate change. Water desalination has become very popular and serves as solar distillation which is proving to be an economical, simple and ecological technique, especially in rural and remote areas. Significant efforts have been made by many researchers in various laboratories to increase and improve the productivity of solar greenhouse distillation. In the present work, emphasis has been placed on the study of a single slope solar distiller having as dimension 50 × 50 cm, in the thickness of the impure water is 1 cm. Natural sand dunes from the El Oued South region of Algeria have been tested as a factor of efficiency improvement. A layer of this sand was deposited on the bottom of the distiller covering the whole surface on which the submit water is emerged. The results show that the productivity of distilled water has unfortunately decreased by 1.46 times.
Sustainable potable water production from conventional solar still during the winter season at Algerian dry areas: energy and exergy analysis

The Algeria Sahara sufers from the scarcity of drinking water. Solar distillation is one of the simplest and generally inexpensive techniques to solve this problem. However, a second problem arises; this is low productivity in winter. The objective of this study is to overcome this difculty by modifying the experimental setup by adding nanoparticles that compensate for the weak solar radiation in winter. The experimental results show that the daily productivity of conventional solar still in summer is 3.5 kg m−2 and in winter is 2.2 kg m−2. Similarly conventional solar still with CuO nanoparticles in winter is 3 kg/m2 per day. The productivity of the conventional solar still without CuO nanoparticles in summer is best as compared to others. When comparing productivity during the winter season, it is found that the productivity of the modifed distillery was 1.4 times better than the productivity of the unmodifed distillery. The daily exergy efciency of the conventional solar still in summer and winter is equal to 1.2 and 1.58%, respectively. The use of CuO nanoparticles in winter season has exergy efciency equal to 2.41%. The daily exergy efciency of the solar still was increased by 52.5% when using CuO nanoparticles in the winter season
