• This study is aimed at estamating the shear stress caused by which rising bubbly flow on sumerged flat-sheet membrane surface using CFD method in MBRs. Shear stress on sumerged flat-sheet membrane surface caused by aeration was simulated using CFD code (ANSYS CFX 11.0) and was compared to measured shear stress by shear sensor and was found to measured time-averaged shear stress values were almost 1.8 times larger than calculated mean shear stress suggesting the calculation of shear stress should be modified therefore suggesting a new method of modifying the shear stress working on the "wall". After modification, both of the calculated mean shear stress and measured shear stress are in good agreement suggesting the effectiveness of CFD for evaluation of mean shear stress on sumerged flat-sheet membrane surface.
