Microbial 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 کاملSmall aggregates can cause nitrite accumulation in one-stage partial nitritation and anammox
Aerobic and anoxic ammonium-oxidizing bacteria (AerAOB and AnAOB) cooperate in partial nitritation/anammox systems to remove ammonium from wastewater. In this process, nitrite accumulation is not desirable, since it decreases the nitrogen removal rate and since it can potentially inhibit the AnAOB. This study addressed several aspects of the microbial aggregate size for three independent types ...
متن کاملIn-situ restoration of one-stage partial nitritation-anammox process deteriorated by nitrate build-up via elevated substrate levels
The one-stage partial nitritation and anammox process (PN/A) has been a promising microbial process to remove ammonia from wastewater especially with low carbon/nitrogen ratio. The main breakdown was the deterioration caused by overgrowth of nitrite oxidizing bacteria (NOB) resulting effluent nitrate build-up in the PN/A process. This study presented an in-situ restoring strategy for suppressin...
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 کاملFull-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...
