This study employed flux-step method to determine the critical flux of MBR system, and the effects of aeration intensity were investigated. The results demonstrated that, for the aeration intensity of 50 and 75 m₃/m₂.h, the critical flux of MBR was kept at 12L/d. But as the aeration intensity being raised to 100 m₃/m₂.h, the corresponding critical flux increased to 18L/d. The increase of aeration intensity resulted in higher measure results of critical flux. Higher effective shear role on the surface of membrane produced by higher aeration intensity was regarded as the main affecting factor for the higher critical flux.
