Abstract :
In this paper, the heat and mass transfer processes in the vacuum membrane distillation (VMD) are discussed. Theoretical models and some correlation equations in common use applied in VMD are analyzed. A method to calculate the mass transfer coefficient is put forward as a result. By this way, the mass transfer coefficient can be figured out by measuring only operating parameters and the mass of permeate without measuring complicated membrane structure parameters such as porosity, pore tortuosity, etc. finally, the mass transfer coefficient is figured out by experiment using a self-made polyvinylidene fluoride (PVDF) hollow fiber modules.
