show Abstracthide Abstract5L continuously fed sequencing batch reactor operated to treat high strength ammonia wastewater via anaerobic ammonium oxidation (anammox). The bioreactor was fed with anaerobic digester filtrate obtained from the belt filter press of a local wastewater treatment plant (CVWRF, Salt Lake City, UT). Prior to entering the anammox reactor, the filtrate was first passed through a nitritation reactor, where half of the influent ammonia was oxidized to nitrite. Details of the anammox bioreactor and initial nitritation reactor can be in Kotay et al 2013 (PMID: 23097129).
