Kväverening från avloppsvatten är nödvändig för att förhindra övergödning av kust och hav. För att avskilja kväve från avloppsvatten används vanligtvis biologisk rening i två steg: nitrifikation och denitrifikation. The big surprise was the serendipitous discovery of the ‘anammox’‐process, whereby ammonium is anaerobically oxidized to dinitrogen gas with nitrite as electron acceptor. The early days of our anammox research are the main focus of this article, which describes the struggle of growing and identifying the most peculiar bacteria we ever came across.

The ANAMMOX ® process is a cost-effective and sustainable way of removing ammonium from effluents and ammonia from waste gas. Compared to conventional nitrification/denitrification savings on operational costs can reach up to 60%, while CO 2 emission is reduced. The ANAMMOX ® conversion is an elegant shortcut in the natural nitrogen cycle.

Projektets övergripande mål är att möjliggöra ökad användning av bakterier som kan utföra anaerob ammoniumoxidation (anammox) för förbättrad kväverening från avloppsvatten med avseende på avskiljningseffektivitet, energianvändning och klimatpåverkan. Anammoxbakterier oxiderar ammonium med nitrit till kvävgas. Anaerobic ammonium oxidation (anammox) bacteria, which combine ammonium and nitrite or nitrate to form nitrogen gas, were discovered in the early 1990s.

The early days of our anammox research are the main focus of this article, which describes the struggle of growing and identifying the most peculiar bacteria we ever came across. Candidatus Kuenenia stuttgartiensis was identified as the dominant anammox bacterium, and its relative abundance in two reactors remained stable throughout the whole operation (200 days). Moreover, with the aid of acclimatization, the activation energy was reduced and the specific growth rate became higher.

This chapter addresses the enrichment and cultivation of anammox bacteria in a sequencing batch reactor (SBR) and a gas lift reactor. 1 A biological two-step process of partial nitritation + anammox. Both steps are carried out by autotrophic bacteria. 2 A method that both reduces nitrogen in the digester supernatant and increases the nitrification in the main stream process through a continuous inoculation of nitrifiers.
