The aqueous glucose solution was separated by the membrane distillation with hydrophobic pojytetrafluoroethylcnc microfiltration membrane, The nominal pore size of the membrane was 0.2${mu}m$. As the operating temperature increased from 40$^{cirt}C$ to 70$^{cirt}C$, the membrane permeation flux increased from 3.6 LMH to IL2 LlVIH, but the glucose rejection decreased 99% to 65% Also, the permeation nux and rejection decreased 25% and 6%, respectively, as the concentration of glucose solution increased 2 wt% to 4 wt%.
