WebThe management of the liquid fraction of digestate produced from the anaerobic digestion of biodegradable municipal solid waste is a difficult affair, as its land application is limited due to high ammonium concentrations and the municipal waste that water treatment plants struggle to treat due to high pollutant loads. The amount of leachate and the pollutant … Anaerobic denitrification coupled to methane oxidation was first observed in 2008, with the isolation of a methane-oxidizing bacterial strain found to oxidize methane independently. This process uses the excess electrons from methane oxidation to reduce nitrates, effectively removing both fixed nitrogen and methane from aquatic systems in habitats ranging from sediment to peat bogs to stratified water columns.
