Enrichment of anaerobic ammonium oxidation (anammox) bacteria for short start-up of the anammox process: a review

The application of the anaerobic ammonium oxidation (anammox) reaction in a biological nitrogen removal system to treat wastewater has become of great interest since its discovery. The anammox reaction is performed by anammox bacteria that belong to the Planctomycete phylum. The reaction occurs in t...
