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: In this article, real-time aeration duration control was used to achieve efficient partial nitrification to nitrite in a sequencing batch reactor (SBR) to treat low strength domestic wastewater.

TL;DR: Preliminary investigation including the abundance evaluation and the identification of filamentous bacteria demonstrated that the limited filamentous bulking could be repeated steadily in a lab-scale anoxic-oxic reactor fed with domestic wastewater.

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.
