Nitrogen 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 کاملModel-based evaluation of complete nitrogen removal through coupling nitritation-Anammox and DAMO
The discovery of denitrifying anaerobic methane oxidation (DAMO) enables the complete N removal from wastewater by utilizing the methane produced onsite from anaerobic digesters. This model-based study evaluates complete nitrogen removal by coupling nitritation-Anammox and DAMO in membrane biofilm reactors (MBfRs). The influences of nitritation produced NO2/NH4 ratio, methane supply and total n...
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...
