Abstract
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%.
공칭크기 0.2${\mu}m$인 소수성 PTFE 정밀여과막을 이용하여 glucose 수용액을 막증류하였다. Glucose 수용액 온도를 40$^{\cirt}C$에서 70$^{\cirt}C$로 상승시킬 경우 막 투과 유속은 3.6 LMH에서 11.2 LMH로 3배가량 증가하였으나 glucose 배제율은 99%에서 65%까지 감소하였다. 또한 glucose 수용액 농도를 2wt%에서 4wt%로 증가시키면 투과유속과 배제율은 각각 약 25% 및 6% 감소하였다.
