Performance Evaluation of a Pilot Solar-Powered Direct Contact Membrane Distillation Unit
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 8
Abstract
Solar-powered membrane distillation (SP MD) is a promising technology in the water desalination field. In this paper, the performance of a pilot SP MD unit located at King Abdulaziz University (KAU), Saudi Arabia was evaluated under different operating parameters during April and July 2018. A thermal analysis showed low process efficiency due to the direct contact MD configuration used. The best energy performance obtained during this study was presented in specific thermal energy consumption and gained output ratio values of 1737 kWh/m3 and 0.37, respectively. Very high energy consumption was found at the startup of the daily operation (up to 4949.2 kWh/m3 ). Operating the unit for seawater desalination gave a maximum daily averaged permeate flux of 3.36 l/m2 h observed during July 14 operation for a total incident solar energy of 3.996 kWh/m2 . Very high salt removal (>99.9 %) was reported in all days of operation.
