Full-scale partial nitritation/anammox experiences--an application survey.
Partial nitritation/anammox (PN/A) has been one of the most innovative developments in biological wastewater treatment in recent years. With its discovery in the 1990s a completely new way of ammonium removal from wastewater became available. Over the past decade many technologies have been developed and studied for their applicability to the PN/A concept and several have made it into full-scal...
متن کاملMicrobial resource management of one‐stage partial nitritation/anammox
About 30 full-scale partial nitritation/anammox plants are established, treating mostly sewage sludge reject water, landfill leachate or food processing digestate. Although two-stage and one-stage processes each have their advantages, the one-stage configuration is mostly applied, termed here as oxygen-limited autotrophic nitrification/denitrification (OLAND), and is the focus of this review. T...
متن کاملMetagenome of the Microbial Community of Anammox Granules in a Nitritation/Anammox Wastewater Treatment System
We sequenced the metagenome of a granular sludge in a nitritation/anammox bioreactor used for the treatment of ammonium-rich wastewater. Proteobacteria, Planctomycetes, Bacteroidetes, Chloroflexi, Ignavibacteriae, and Acidobacteria were the predominant phyla in the studied bioreactor. Binning of contigs yielded a near-complete genome of the dominant anammox bacterium assigned to the candidate g...
متن کاملThe role of inoculum and reactor configuration for microbial community composition and dynamics in mainstream partial nitritation anammox reactors
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 investiga...
متن کاملGenome-based microbial ecology of anammox granules in a full-scale wastewater treatment system.
Partial-nitritation anammox (PNA) is a novel wastewater treatment procedure for energy-efficient ammonium removal. Here we use genome-resolved metagenomics to build a genome-based ecological model of the microbial community in a full-scale PNA reactor. Sludge from the bioreactor examined here is used to seed reactors in wastewater treatment plants around the world; however, the role of most of ...
