Integrating 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 کاملCombined anaerobic ammonium and methane oxidation for nitrogen and methane removal.
Anammox (anaerobic ammonium oxidation) is an environment-friendly and cost-efficient nitrogen-removal process currently applied to high-ammonium-loaded wastewaters such as anaerobic digester effluents. In these wastewaters, dissolved methane is also present and should be removed to prevent greenhouse gas emissions into the environment. Potentially, another recently discovered microbial pathway,...
متن کاملA laboratory investigation of interactions between denitrifying anaerobic methane oxidation (DAMO) and anammox processes in anoxic environments
This study investigates interactions between recently identified denitrifying anaerobic methane oxidation (DAMO) and anaerobic ammonium oxidation (anammox) processes in controlled anoxic laboratory reactors. Two reactors were seeded with the same inocula containing DAMO organisms Candidatus Methanoperedens nitroreducens and Candidatus Methylomirabilis oxyfera, and anammox organism Candidatus Ku...
متن کاملNew molecular method to detect denitrifying anaerobic methane oxidation bacteria from different environmental niches.
The denitrifying anaerobic methane oxidation is an ecologically important process for reducing the potential methane emission into the atmosphere. The responsible bacterium for this process was Candidatus Methylomirabilis oxyfera belonging to the bacterial phylum of NC10. In this study, a new pair of primers targeting all the five groups of NC10 bacteria was designed to amplify NC10 bacteria fr...
متن کاملBiological Nitrogen Removal Using Anaerobic Ammonium Oxidation
ANaerobic AMMonium OXidation (Anammox) is an efficient microbiological process for the removal of ammonia nitrogen from wastewater. Although several Anammox reactors have been operated successfully in European water pollution control plants, there are challenges associated with the process which must be addressed to ensure dependable performance when treating high strength wastestreams in New Y...
