Abstract

A error function model was established to predict the total resistance of a 0.1 μm polyacrylonitrile (PAN) flat-sheet microfiltration membranes fouled with 1.46 g/L activated sludge suspension during the constant pressure backwash process under different operating conditions (backwash strength and temperature). The results showed that the total resistance of the fouled membrane decreased with increasing backwash intensity or temperature. The model predictions aligned well with experimental data under all tested conditions (R² > 0.91). Additionally, the model parameter k effectively evaluated cleaning efficacy: smaller k value indicating better cleaning efficiency.
