Abstract：

Hydrodynamics of an MBR system and its contour of velocity and wall shear stress were simulated with computational fluid dynamics (CFD). Different hydraulic conditions were obtained by changing the distance between the membrane module and aerator. Due to different configurations, it was proved that hydraulic conditions of MBR with glass fiber tubular membrane modules were better than that with flat membrane modules for membrane fouling control by comparing both of the Reynolds number and mass flow rate. Moreover, the distribution of velocity was more homogeneous in the system with four aerators than that with only one aerator. From the research results, it could be said that CFD is powerful tool used for hydrodynamic study in MBR and its membrane fouling control.
