|Abstract:||Modeling of an experimental study on the fouling mechanisms of mullite ceramic membranes for treatment of oily wastewaters in a hybrid microfiltration - powdered activated carbon process (MF-PAC) has been presented. Hermia’s models for cross flow filtration have been employed to investigate the fouling mechanisms of membranes at different time intervals with different PAC concentrations. Results show that cake filtration model can be applied for prediction of permeation flux decline for MF and MF-PAC process up to 800 ppm PAC concentration. Intermediate pore blocking model can be applied for MF-PAC with 1200 ppm PAC concentration. Average error for prediction of permeation flux with cake filtration model for MF process is found to be 0.11% and for MF-PAC process with 100, 200, 400 and 800 ppm PAC concentration the errors are equal to 3.67, 2.89, 5.73 and 4.75% respectively. Additionally, for MF-PAC process with 1200 ppm PAC, average error for prediction of permeation flux with intermediate pore blocking model is 1.34%.|
