Only two decades ago it was discovered that NH 4 + can also be removed by anaerobic ammonium oxidation in WWTPs (anammox; Mulder et al. 1995).By the anammox process, the bacteria oxidize NH 4 + with NO 2 − to N 2, which is an autotrophic N-removal pathway without the need of organic carbon input (Strous et al. 1998) and therefore more cost efficient.. Efficient BNR by anammox in municipal

Anammox was discovered in 1995 in a wastewater treatment plant in Delft (NL), but now it is clear that it is the main nitrogen cycle process that contributes up to 50% to the removal of fixed nitrogen in the oceans. However, anammox bacteria grow very slowly, with only about 15 generations per year.

Forskningsprojekt , 2015 – 2017. 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 nitrifi the anammox process was discovered (Mulder et al., 1995).

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.

Försöken har utförts vid Hammarby som ANAMMOX-bakterien (Amba et al. 2007). Namnet ANAMMOX står för ANaerobic AMMoni-um OXidation och det speciella med bakterien är att den kan rena kväve utan behov av den kolkälla som annars behövs vid normala denitrifikationsprocesser.

PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) was used in this study to predict the metagenomic potentials and characterize the microbial community structure and functional features in anammox aggregates (e.g Anammox is the process where ammonium is oxidized to nitrogen gas with nitrite as electron acceptor. Anammox has been implemented for treatment of the sludge liquor in wastewater treatment plants around the world.

Anammox-based systems for nitrogen removal from mainstream municipal wastewater2017Doktorsavhandling, sammanläggning (Övrigt vetenskapligt). Abstract

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. Anammox bacteria have strong motility and high attachment capability. Anammox bacteria possess strong EPS synthesis regulated by quinolone. c‐di‐GMP synthesis enables a … Anammox species enrichment in situ increases the nitrogen removal rate, and it has been proven that anammox has a high nitrogen removal contribution rate and is the key to the stability and engineering application of the denitrification coupling process, which was successfully used in urban sewage treatment plants. An integrated approach to document high anammox activity and biodiversity in a constructed wetland (CW) was performed and showed that substantial anammox activity could mitigate undesirable N2O emission.

During the 2000s, the process has been introduced into sludge liquor treatment worldwide. The step to introduce anammox in the mainstream is de-creasing, but lab- and pilot-scale studies on real municipal wastewater are yet lacking. However, several pilot En fungerande process med anammox kräver att man optimerar önskad mikrobiell samverkan och minimerar oönskad konkurrens. Anammoxprocessen har implementerats på nästan 100 avloppsreningsverk i världen för behandling av varma, högkoncentrerade rejektvatten från avvattning av rötat avloppsslam och industriavlopp.
