TL;DR: The feasibility of achieving stable operation in the treatment of 50 mg/L ammonia wastewater with a micro granule-based PN/A reactor and ex-situ activity tests showed the activity of NOB was well limited through DO regulation in the reactor provide an alternative Pn/A process configuration for low-strength wastewater treatment by sustaining microstate granules.

TL;DR: The resilient archaeal community was found even after serious inhibition in both reactors, and obvious dynamics of bacterial communities were observed in acidogenic and hydrolytic functional bacteria following TAN variation in the different stages.

TL;DR: Findings suggest that a succession of microflora was successfully established along the DHS, with greater numbers of nitrifying bacteria in the 2nd and 3rd units than in the 1st unit, corresponding with the observed ammonium oxidation pattern of the reactor.

TL;DR: In this paper, a moving bed reactor with functional carriers (30% filling rate) was developed to treat a synthetic influent with 50 mg/L ammonia, and the long-term operation results showed nitrogen removal efficiencies of 71.7 ± 9.1% have been stably obtained under a relatively short hydraulic retention time of 2 h.

TL;DR: Primary component analysis clearly indicates that both bacterial and archaeal communities create independent clusters according to substrate types, and Canonical correlation analysis and variance partitioning analysis implied that bacterial and Archaeal community variations were significantly affected by substrate and the operation conditions.
