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 As Anammox bacteria favour anaerobic condi-tions, the Anammox process is reversibly inhibi-ted by the dissolved oxygen (DO) concentration. The effect of oxygen on process performance is described in the following sub-chapter. The effect of oxygen on Anammox bacteria has been exa-mined in marine ecosystems (OMZs). The results Anammox is an autotrophic nitrogen removal process that produces nitrogen gas from nitrite and ammonium without the need for organic carbon sources (Equation (1)) (Strous et al. 1998).

The Anammox is an autotrophic process so there is no need for external carbon to support the formation of dinitrogen (Johansson et al. 1998, Strous et al. 1997).

Research. The research on the nitritation/anammox process is a currently ongoing project at the Eawag. The understanding of the whole process (kinetics, inhibitions, regulation, adaptation) is being improved by investigating the key specific growth rates and by compiling all relevant processes in a mathematical model. Biological nitrogen removal by the anaerobic ammonium oxidation (anammox) process is becoming increasingly recognized for applications in wastewater treatment plants (WTPs). This group of

2012-07-15 · Anaerobic ammonium oxidation (Anammox), a process ideally suited for the treatment of nitrogen-rich wastewater streams, is a promising novel biological nitrogen elimination process with attractive application prospects. Der Anammox-Prozess ist nicht nur von akademischem Interesse, sondern bietet eine vielversprechende Alternative zu der klassischen Methode in Kläranlagen, Stickstoffverbindungen zu entfernen. Wohl aus diesem Grund wurden auch schon mehrere Patente in Zusammenhang mit dem Anammox-Prozess erteilt. Se hela listan på brighthubengineering.com Research. The research on the nitritation/anammox process is a currently ongoing project at the Eawag.
The bacteria mediating this process were identified in 1999, and were a great surprise for the scientific community. [2]
Anammox stands for Anaerobic Ammonium Oxidation. The process was discovered in the early nineties and has great potential for the removal of ammonia nitrogen in wastewater.

The effect of oxygen on Anammox bacteria has been exa-mined in marine ecosystems (OMZs). The results Anammox is an autotrophic nitrogen removal process that produces nitrogen gas from nitrite and ammonium without the need for organic carbon sources (Equation (1)) (Strous et al. 1998). It has been proposed as a promising way of saving the aeration-energy cost of nitrification and the chemical cost of denitrification. (1) After a most cumbersome procedure to revive the anammox process in a pilot fluidized‐bed reactor Astrid van de Graaf added (15 N)‐labelled ammonium to the reactor which was fed unlabelled (14 N)‐nitrate and to our immense joy the mass spectrometer showed that the majority of the label ended up in mixed labelled 14,15 N‐N 2 gas (reaction 2A). ANAMMOX® Operation principle The Anammox® reactor is a reactor ® system in which nitritation and anammox conversion occur simultaneously in one single process unit. The natural nitrogen cycle involves various biological processes.
