Abstract：

Membrane fouling is a key problem to be solved in MBR. In order to mitigate the membrane fouling without extra energy consumption, a new folded plate membrane module was designed by modifying the configuration of the flat sheet membrane module. The constant trans-membrane pressure (TMP) membrane filtration experiments were conducted to optimize the vertical inclination angle and membrane spacing of the folded plate membrane module, and the particle image velocimetry (PIV) technology was used to characterize the feature of flow field near the membrane surface. Finally, the application of the folded plate membrane module in MBR was to investigate its antifouling property and effluent effect. The research results showed that, the optimal vertical inclination angle and membrane spacing of the folded plate membrane module were 15° and 30 mm, respectively. And a larger stable flux could be obtained when the aeration position was directly below the folded plate membrane module. Additionally, the rising rate of TMP of the folded plate membrane module was 0.4 times as fast as that for the flat sheet membrane module, and the removal rate of COD and NH3-N for both folded plate membrane module and flat sheet membrane module were above 90% and 80%, respectively.
