Experimental Studies on a Multi-Stage Solar Desalination Plant (MSD) under Moroccan Climate

 In this chapter, we’ve described a solar desalination system that consists of an evaporation/condensation unit made up of a bottom basin and eight horizontal stages, connected to a field of four flat thermal collectors, each with a surface area of 2.1 m2, and a pump powered by photovoltaic panels. An experimental measurement of the desalination system was used to validate a simulation model that used a numerical solution to a set of differential equations characterising the system. According to the MSD system’s testing findings, the highest stage temperatures for the 2020–2022 growing season will be 90°C, and the system will produce a maximum of 50–60 litres of water with a conductivity of 50–70 s/cm and a salt level of 0.045 g/L. In order to ensure the production of pure (drinking) water with a conductivity (2700 s/cm) and a salt content (500 mg/L), from a high conductivity well (4050 s/cm) and salt content (> 2720 mg/L), by solar energy, this pilot station in Douar Al Hamri, in the rural town of Boughriba in the Province of Berkane, Morocco, was installed and tested in the weather conditions of this isolated region The simulations and the experiment have great agreement, as shown by the modelling of these experimental data using the thermal equations established throughout this work. The evaluation of all the data and comparisons with the literature make it abundantly evident that the MSD system blocks established during this effort are operating effectively.
