Membrane distillation (MD) is a non-isothermal membrane separation process capable of
operating at low temperature and low transmembrane hydrostatic pressure. Air gap
membrane distillation (AGMD) is one of the MD configurations. In this study, the performance
of double-stage AGMD unit at different AGMD-operating parameters such as feed
temperature, feed flow rate, coolant temperature, coolant flow rate and air gap width is
presented. Experimental results revealed that the built double-stage AGMD unit is capable …
