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...
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...
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 ...
