- Abstract
- This paper demonstrates modelling of the aerobic granular sludge (AGS) process with the pseudoanalytical solutions (PAS) of a biofilm model. A MATLAB programmed graphical user interface platform was developed to facilitate the model calculation and access. Model calibration and validation were carried out through using experimental data collected from a granular sludge sequencing batch reactor operation. The experimental and modelling results identified the
distribution of heterotrophs and nitrifiers on the AGS and its contribution to the performance of
wastewater treatment. The model could describe multi-species biofilms according to the
distinguishing features among the three levels of PAS models. The models demonstrated increasing degrees of interaction (no interaction, competition for nitrogen and layering and protection) between heterotrophs and nitrifiers. Modelling the AGS process using PAS increases the accessibility of the simulation of multiple species in both biofilm and suspended biomass.
