Evaluating the roles of coexistence of sludge flocs on nitrogen removal and nitrous oxide production in a granule-based autotrophic nitrogen removal system

Dynamic modelling of N2O emissions from a full‐scale granular sludge partial nitritation‐anammox reactor

“…Mathematical modelling has been proven a very useful tool for analysing nitrogen removal performance (Hao et al, 2002; Mozumder et al, 2014) as well as N 2 O formation mechanisms in partial nitritation‐anammox systems (Chen et al, 2019; Liu et al, 2020; Wan et al, 2021). N 2 O models have rapidly evolved in the past few years, from single‐pathway models (Mampaey et al, 2011), describing only one N 2 O formation pathway, to multiple‐pathway models (Domingo‐Félez & Smets, 2016; Ni et al, 2014; Pocquet et al, 2016) in which the interactions between different pathways are considered.…”
