Abstract Background Aerobic granular sludge (AGS) has emerged as a novel wastewater treatment technology and suppressing alternative to conventional activated sludge. The development of mathematical models the AGS process, which can be used for plant (WWTP) design optimization, is therefore necessary support successful implementation technology. This study aims develop zero‐dimensional (0D) model that in engineering practice above‐mentioned purposes. Results A laboratory sequencing batch reactor (SBR), removing soluble organic substrate, nitrogen phosphorus, was fed with artificial modelled using 0D approach. Model supported by bacterial characterization 16S rRNA gene amplicon high‐throughput sequencing. based on no. 2d (ASM2d) extended both two‐step nitrification implemented simulator Sumo19 (Dynamita SARL) ammonia adsorption desorption according Langmuir model. variations nitrogen, nitrite nitrate orthophosphate phosphorus dissolved oxygen concentrations during one cycle SBR were successfully reproduced (all Pearson's r values ≥0.93 all 2 ≥ 0.86). Conclusions modelling approach proven applicable AGS. It possible fill gap developed between research biofilm community. merits further exploration reactors real wastewater, well pilot full‐scale WWTPs. © 2022 Society Chemical Industry (SCI).
