Nanofiltration Separation of Monosaccharide Solution Under High Concentrations
摘要
Abstract
In this paper, the influence of three operation factors namely feed concentration,operating pressure and temperature on the performance of nanofiltration membrane separation at high solution concentrations is evaluated using glucose aqueous as solution with a commercial spiral-wnund nanofiltration membrane. At lower solution concentrations.operating pressure has more impact on permeate volume flux,while less on the rejection. On the other hand,the results are opposite at higher solution concentrations. As the operating pressure increased, the raising rate of permeate volume flux increases with the operating temperature, while the falling rate of rejection reduces with the operating pressure. In the cases of high solution concentrations,the increasing rate of permeate volume flux changing with temperature decreases with operating pressure,and the declining rate of rejection increases with operating pressure. The investigation results in this work provide guidance for optimizing the design and operation conditions for industrial nanofiltration processes thus to enhance the efficiency and reduce the raw material wastage.关键词
