Structural design of some components of the hybrid MED solar still was improved.
• Performance of the still proposed depends more on the MED section than the basin section.
• Larger feeding flow rate shows better performance for the still with an insufficient plate number.
• Maximum performance of the still achieved at the maximum productivity condition of the 2nd plate.
• Productivity of the still increases linearly with heat input, recording 18.02 kg/m2 at 22.37 MJ/d.
