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.

多年来，全球许多地方的饮用水供应量正在减少，并且许多水资源受到污染或未被净化。由于干旱和气候变化，北非面临着严重的水资源短缺。水脱盐已经变得非常流行，并且可以用作太阳能蒸馏，事实证明这是一种经济，简单和生态的技术，特别是在农村和偏远地区。许多实验室的许多研究人员已经做出了巨大的努力，以增加和提高日光温室蒸馏的生产率。在目前的工作中，重点是对不纯水的厚度为1 cm的尺寸为50×50 cm的单斜太阳能蒸馏器的研究。来自阿尔及利亚El Oued南部地区的天然沙丘已经过测试，可以提高效率。一层这样的沙子沉积在蒸馏器的底部，覆盖了产生水的整个表面。结果表明，蒸馏水的生产率不幸降低了1.46倍。
