| 제목 | Scale-up study on nanofiltration(NF) membrane using Donnan Steric Pore Model and Dielectric Effect (DSPM-DE) |
| 초록 | The membranes are categorized into four types which are microfiltration (MF), ultrafiltration (UF), NF, and reverse osmosis (RO). NF membrane has pore size of approximately 1nm, which the size is in the between UF and RO membrane. Like RO, NF is used to separate inorganic salts and small organic molecules but it possesses distinct feature that it shows high rejection performance on the multivalent anion and high water flux. To fully utilize the potential of NF, simulating the membrane performance is necessary. The predictive model used in this study is DSPM-DE which explains the separation mechanism by size exclusion, charge effect, and dielectric effect. With this model, laboratory scale result and flat sheet result will be simulated and the difference between them will be studied. If these two results are similar, the time and money for scale-up research will be greatly reduced. The membrane size is 140cm2 in case of laboratory scale and is 1m2 in case of pilot scale. |
