TL;DR: Comparing the performance of partial nitrification via nitrite and microbial community structure were investigated and compared in two sequencing batch reactors with different dissolved oxygen (DO) levels indicated that selecting properly DO level and adopting process control method is not only of benefit to the achievement of novel biological nitrogen removal technology, but also favorable to sludge population optimization.

TL;DR: It is suggested that the selective enrichment of AOB as well as the washout of NOB be obtained by process control before making the biomass slowly adapt to low temperatures for achieving partial nitrification to nitrite at low temperatures.

TL;DR: The mechanism of nitrous oxide emission during these processes and the specific control strategies are explained or proposed, and several urgent issues and significant perspectives related to these novel pathways and players have been addressed to evoke the involvement of researchers in broadening future studies.

TL;DR: The penetration property of filament cell wall should be considered or tested before the selection of biocide type in practice, as it implied that CTAB might have more penetration capacity to cell wall of chlorine-resistant Type 021N bacteria.

TL;DR: It was demonstrated that stable maintenance of LFB for energy saving was feasible by process control and optimization.
