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

Abstrakt

This study aimed to model and optimize mainstream deammonification in an integrated fixed-film activated sludge (IFAS) pilot plant under natural seasonal temperature variations. The effect of gradually decreasing temperature on the performance was evaluated during a winter season and a transition period to summer conditions, and the correlation of the performance parameters was investigated using principal component analysis (PCA). The optimization of intermittent aeration in the long-term (30 days) dynamic conditions with on/ off ratio and dissolved oxygen (DO) set-point control was used to maximize the N-removal rate (NRR) and Nremoval efficiency (NRE). Optimization results (DO set-point of 0.2–0.25 mgO2/L, and on/off ratio of 0.05)
