Realization of a reduced model of a water distillation station by solar energy: Case study in Africa for Consumption or Irrigation

Abstract

This study concerns the use of clean energy for technical purposes; so we were interested in a simple technique for desalination of seawater, in this case, the distillation by solar radiation.

At the beginning of the study we focused on different solar distillation processes with theoretical description of the phenomenon.

Subsequently, we defined, in general, the radiation in Algeria, before proceeding directly to the practical part of solar distillation by the use of a prismatic glass test bench.

The prototype used at a distillation capacity of 20 litters, it can be moved to the place deemed appropriate, and is equipped with temperature and humidity sensor transmitting the measurement to an Arduino Uno allowing to display the results on an LCD screen or recorded on PC.

Thus, after sampling of seawater, tests and measurements were made on the prototype, placed in a sunny spot near the University of PAUWES, followed by laboratory analysis and discussion of the results.

The various measurements and analyses carried out have demonstrated that the prototype is suitable for the distillation of brines, the salinity level analysed indicates that distilled water is even good for domestic consumption.
