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 کاملIntegrating landfill bioreactors, partial nitritation and anammox process for methane recovery and nitrogen removal from leachate
A new process consisting of a landfill bioreactor, partial-nitritation (PN) and the anammox process has been developed for landfill leachate treatment. In this study, the landfill bioreactor exhibited excellent performance in methane-rich biogas recovery, with a specific biogas yield of 0.47 L gas g(-1) COD and methane percentages of 53-76%. PN was achieved in the aerobic reactor by high free a...
متن کاملNitrogen removal by a nitritation-anammox bioreactor at low temperature.
Currently, nitritation-anammox (anaerobic ammonium oxidation) bioreactors are designed to treat wastewaters with high ammonium concentrations at mesophilic temperatures (25 to 40°C). The implementation of this technology at ambient temperatures for nitrogen removal from municipal wastewater following carbon removal may lead to more-sustainable technology with energy and cost savings. However, t...
متن کاملPartial Nitritation/anammox and Canon – Nitrogen Removal Systems Followed by Conductivity Measurements
The deammonification process is a new biological promising method for a separate treatment of ammonium-rich digester supernatant. Its application can significantly reduce the nitrogen load in Wastewater Treatment Plants (WWTPs). The method is a two-step process and it can be accomplished in two separate stages (partial nitritation and Anammox) or in a singe one (CANON). Both these systems were ...
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 ...
