In real MBRs, the fouling phenomenon is too complex and cannot be described using single fouling mechanism. Therefore, in this study, a combined fouling model (which is obtained by combining four constantflowrate blocking mechanisms) is proposed to investigate the complex phenomenon of fouling mechanisms. Using the combined fouling model, 1) prediction of the future MBR fouling and 2) determination of the dominant mechanisms to MBR fouling are carried out. To consider the affect of continuous changes in fouling on the future data prediction, the combined model is developed and analyzed using two methods: 1) global prediction method (model with the parameters fitted for the data of whole operational period) and 2) recursive prediction method (timely updated model with the parameters fitted for the data of intermediate time periods). The RMSEs are used to compare the prediction accuracies of the global and recursive fouling model, and recursive fouling model represents better prediction capability, since it reflects the affect of continuous changes in fouling on the future fouling prediction. In addition, among the several fouling mechanisms, the intermediate blocking and cake filtration are most contributed to the MBR fouling within the MBR filtration process.
