• The aim of this study was the long-term validation of a model capable of reproducing the filtration process occurring in a submerged anaerobic membrane bioreactor (SAnMBR) system. The proposed model was validated using data obtained from a SAnMBR demonstration plant fitted with industrial-scale hollow-fibre membranes. The validation was carried out using both lightly and heavily fouled membranes operating at different bulk concentrations, gas sparging intensities and transmembrane fluxes. Across a broad spectrum of operating conditions, the model correctly forecast the respective experimental data in the long term. The simulation results revealed the importance of controlling irreversible fouling in order to ensure sustainable long-term membrane performance. •A filtration model for SAnMBRs has been validated using long-term data.•The model was validated for lightly and heavily fouled full-scale HF membranes.•Different MLTS levels, gas sparging intensities and permeate fluxes were applied.•The model reproduced the experimental data accurately.
