Denitrifying anaerobic methane oxidation (DAMO) coupled to anaerobic ammonium oxidation (anammox) is a promising technology for complete nitrogen removal with economic and environmental benefit. In this work, a model framework integrating DAMO and anammox process was constructed based on suspended-growth systems. The proposed model was calibrated and validated using experimental data from a

The anammox process occurs under anaerobic conditions by bacterial mediated combination of NO 2 with NH 4. The reaction was first suggested by Richards (1965) and first shown directly to occur in wastewater bioreactors (Mulder et al., 1995). The anammox reaction uses NH 4 produced during oxidation of organic matter required for denitrification.

The bacteria that perform the anammox process are genera that belong to the bacterial phylum Planctomycetes. One of the most significant and widespread uses of the anammox reaction is the treatment of sewage and wastewater to remove ammonium. The complete oxidation of ammonia to dinitrogen is desired in wastewater treatment. While this by itself is thermodynamically possible, it is biochemically impossible.

Anaerob ammoniumoxidation (Anammox) är en ny process som, till skillnad från would have a total reaction volume of approximately 200 m3 with carrier

Denitrification appeared as the main nitrogen-reducing process in the bioreactor due to more abundant levels of functional genes. a hypothesis, that the oxygen concentration in the bulk liquid and the nitrite production rate are the limiting factors for the Anammox reaction in a single reactor. Reaction products released to the air are highly oxygenated.

Even though anammox is a key biogeochemical process of equal importance, These results present a new biochemical reaction forging an N-N bond and fill a

Anammox (anaerobic ammonium oxidation), which is a reaction that oxidizes ammonium to dinitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle. The reaction is mediated by a specialized group of planctomycete-like bacteria that were first discovered in man-made ecosystems. The anammox process occurs under anaerobic conditions by bacterial mediated combination of NO 2 with NH 4. The reaction was first suggested by Richards (1965) and first shown directly to occur in wastewater bioreactors (Mulder et al., 1995). The anammox reaction uses NH 4 produced during oxidation of organic matter required for denitrification. The Anammox reaction can be represented as NH 4 - + NO 2 - = N 2 + 2H 2 O. This reaction is carried out by Anammox bacteria (Candidatus Brocadia anammoxidans) belonging to the group of planctomycete (SHIVARAMAN and SHIVARAMAN 2003).

The group of bacteria able to perform the anammox reaction was then identified at Delft University (van der Graaf et al., 1996), and also found back in other treatment plants showing that it was more commonly present than previously thought. Anammox bacteria are slow growers and they have a doubling time of 11-20 days (Strous et al., 1999).
