Abstract: |
|
Based on the theory of membrane foulingasymmetric distributionalong axial hollow fiber membrane,the dynamic models of membrane resistance related to time and space under variation flux condition in ultrafiltration of hollow fiber membrane were established by Response Surface Methodology (RSM). Theremarkableanalysis and experiment have been carried out to verify this model.The optimization of the hollow fiber membrane module was performed using the model. The verification suggests thatmodel calculated value agrees with experimental valuewell.Analysis of this model showedthat in the subcritical flux condition, there was an optimum value of membrane fiber length and operation time.In the critical and supercritical state,membrane resistance is proportional to the fiber length and operational time. |
