An Experimental Study of a Solar Still: Application on the sea water desalination of Fouka

Abstract Today, seawater and brackish water desalination is a subject of concern of many researchers all over the world. The recourse to the desalination by distillation using solar energy represents an appreciable element of the water resource and constitutes a realizable, simple, profitable, operational solution technically. The present study, which is essentially experimental, is interested in the effect of the internal parameters on a double slope plane solar still. In this work, the solar still was conceived and realized by our team of research. The experiments were carried out at different conditions. The variation of the different operating parameters of the solar still has been studied. It is found that the distillate production rate increases when the difference between the temperature of water and glass decreases. Distillated water was also, influenced by the presence of wind and the climatic changes which decrease the amount of diffuse solar energy received by the brackish water. The average yield of distilled water was 4 L/m2 /day.
