Abstract:	This paper presents the simulation study of Direct contact membrane distillation (DCMD) and air gap membrane distillation (AGMD) for desalination. Simulation models are built on Aspen Plus platform as user defined unit operations for the two types membrane distillation, respectively. Large scale modules for practical industrial applications are simulated and studied for the effects of design and operation variables, as well as the importance of heat and mass transfers of each phase. For each type of module with heat recovery design, Response Surface Method is applied to develop the performance-variables quadratic model, followed by multivariable optimization. Optimal designs can realize separation efficiencies of 8.2% and 5.8% for DCMD and AGMD, respectively.
