英文摘要 | The present modified boundary-layer resistance model (MBR model) includes the effect of osmotic pressure of the concentrated boundary layer on the flux. Ultrafiltration experiments were conducted in a hollow-fiber membrane module with dextran T500 aqueous solution as tested solution. The predict by the MBR model is better the osmotic pressure model or the boundary-layer resistance model and agrees pretty well with the experimental result. The over-estimation of the present model is due to the neglect to the fouling resistance. |
