Performance evaluation and model-based optimization of the mainstream deammonification in an integrated fixed-film activated sludge reactor

[Display omitted] •Mainstream pilot-scale deammonification was simulated under seasonal temperature.•Intermittent aeration strategy plays an important role in stable NOB suppression.•The aeration was set to the optimized values (DO = 0.2 mgO2/L, on/off ratio = 0.05).•The nitrogen removal efficiency...
