%X Membrane bioreactors (MBRs) are attracting global interest but the mathematical modeling of the biological performance of MBRs remains very limited. This study focuses on the modelling of a side-stream MBR system using Activated Sludge Model No. 1 (ASM1), and comparing the results with the modelling of traditional activated sludge processes. ASM1 parameters relevant for the long-term biological behaviour in MBR systems were calibrated (i.e. Y(H) = 0.72gCOD/gCOD, Y(A) = 0.25gCOD/gN, b(H) = 0.25 d(-1), b(A) = 0.080 d(-1) and f(P) = 0.06), and generally agreed with the parameters in traditional activated sludge processes, with the exception that a higher autotrophic biomass decay rate was observed in the MBR. A sensitivity analysis for steady state operation and DO dynamics suggested that the biological performance of the MBR system (the sludge concentration, effluent quality and the DO dynamics) are very sensitive to the parameters(i.e. Y(H), Y(A), b(H), b(A), micro(maxH) and micro(maxA)), and influent wastewater components(X(I), S(S), X(S), S(NH)).
