| Abstract: | Membrane fouling is one of the main factors affecting the large-scale application of membrane bioreactors. The presented study of a model to describe the forming of resistance of the cake layer in membrane bioreactor applications for wastewater treatment and effect factors of this model are studied. The optimized model confirms that MLSS and cross-flow velocity are the key effect factors on the resistance of cake layer. Moreover, the results of short-term experiments validate this model better and there are optimum values of the above parameters. |

| Keywords: | MBR resistance of the cake layer model MLSS cross-flow velocity |
