The role of inoculum and reactor configuration for microbial community composition and dynamics in mainstream partial nitritation anammox reactors

Abstract: Implementation of partial nitritation anammox (PNA) in the mainstream (municipal wastewater treatment) is still under investigation. Microbial community structure and reactor type can influence the performance of PNA reactor; yet, little is known about the role of the community composition of the inoculum and the reactor configuration under mainstream conditions. Therefore, this study investigated the community structure of inocula of different origin and their consecutive community dynamics in four different … Show more

“…As also reported for other PNA MBBRs (Agrawal, et al 2017, Persson, et al 2017, the dominant 271 taxa in the biofilms were AMX ( Figure 4A), with Brocadia being the only AMX genus detected. 272…”

“…PNA combines oxidation of part of the wastewater ammonium to nitrite by ammonia oxidising 41 bacteria (AOB) and a subsequent conversion of the nitrite and remaining ammonium to nitrogen gas 42 by anammox bacteria (AMX). PNA communities are often grown in biofilms in granule reactors or in 43 moving bed biofilm reactors (MBBRs) to maintain the slow growing AMX at high concentrations in 44 the reactors (Agrawal, et al 2017). 45 46 Implementation of PNA for the colder, more diluted mainstream of wastewater, which contains the 47 majority of the nitrogen at WWTPs, has been challenging.…”

“…The presence and composition of denitrifiers in the PNA systems based on 16S rRNA gene amplicon sequencing has been extensively reported (Agrawal et al, 2017;Du et al, 2019;Laureni et al, 2015;Persson et al, 2017;D. Wang et al, 2019).…”

“…In this instance, the use of carriers can be used to provide a large surface area to achieve high biomass retention (40) . Carriers supporting attached biofilm growth can be applied in various configurations, for instance, in rotating biological contactors (41) , moving bed biofilm reactors (42, 43) and sequencing batch biofilm reactors (44) . However, when AnAOB form granules in a Ca .…”
