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 کاملThe Effect of Influent Characteristics and Operational Conditions over the Performance and Microbial Community Structure of Partial Nitritation Reactors
Nitrogen is a main contaminant of wastewater worldwide. Novel processes for nitrogen removal have been developed over the last several decades. One of these is the partial nitritation process. This process includes the oxidation of ammonium to nitrite without the generation of nitrate. The partial nitritation process has several advantages over traditional nitrification-denitrification processe...
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 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...
