This paper covers the details and results of experimental and simulation work carried on an Air Gap Membrane Distillation (AGMD) unit, as a part of EU MEDESOL research project. The aim of the experimental work, carried out during a two-week period, was (a) to evaluate the MD performance with saline water (35 g/l NaCl) establishing an operation data base, and (b) to conduct a system simulation for the design and evaluation of a three-stage MD desalination system. Experimental results shows that production was 30-40% less in the case of using 35 g/l salinity compared with 1 g/l. Experimental-based simulations of a three step MD system of two arrangement layout were employed to assess the heat demand. Specific thermal energy consumption was calculated as 950 kWht/m3 for a layout without heat recovery, and 850 kWht/m3 for the layout with one stage heat recovery.
