Designing a combinational solar water desalination system and investigation of solving sedimentation of minerals with water input from the Persian Gulf.

In this research, an active combinational solar water desalination system was designed and investigated. Sea water was guided towards a solar collector and was evaporated in a glass chamber where the produced vapor was conducted towards a water cooled condenser using a compressor, thereby resulting in the production of distilled water. In the first experiment, the corrosion test was performed to investigate the occurrence of corrosion in the solar collector and the floor of the glass chamber. According to the corrosion test performed in the first experiment, the corrosion rate of copper, the galvanized sheet, and stainless steel was measured to be 21.874, 24.356, and 17.595 mm/year, respectively. In order to reduce corrosion in the system, a descaling solution (acetic acid) was used, where the results of the corrosion test for copper and the galvanized sheet in the presence of the descaling solution were measured to be 14.759 and 14.795 mm/year, respectively. Considering the closeness of the corrosion rate of the galvanized sheet and the stainless steel sheet, as well as the finished price of the sheet employed in the floor of the glass chamber, the application of the galvanized sheet is more economical than the use of the stainless steel sheet.
