Abstract—Membrane distillation (MD) is receiving recent attention as a technique to efficiently concentrate aqueous solution. It has potential benefits of low temperature and pressure operation with high degrees of separation. Orange Juice has to be concentrated by direct contact membrane distillation. The Dusty Gas Model describes membrane distillation through a porous membrane. Analysis of an applied Dusty Gas Model has identified a possible way to optimise flux by an optimal combination of operating parameter and design factor. A model for a membrane distillation process in a plate-and-frame unit has been developed. It is based on a mass and energy balance equation for hydrodynamic, temperature and concentration boundary layers. The model takes into account energy interdependence between flow in feed and in permeate channels. Amodeltaking into consideration temperature concentration polarization (TCP) predicts temperature and concentration values at the membrane surface. The model consists of an analytical equation and permits simulation or analysis of the influence of various factors to permeate flux.
