One of such systems is based on the process of anaerobic ammonium oxidation ( Anammox), which is a new powerful tool especially for strong nitrogenous 

The anaerobic ammonium oxidation (AMX) process was predicted in theory based on nitrogen profiles and thermodynamic computations in 1977 (Broda, 1977) and firstly described in a denitrifying fluidized-bed reactor at Delft University of Technology, the Netherlands in 1990 (Mulder et al., 1995). To date, this process has only been reported for some bacteria belonging to the order Planctomycetales. The anammox process has been demonstrated to be a better substitute for conventional techniques because the utilization of anammox bacteria in wastewater treatment diminishes the energy utilization of wastewater treatment plants since without the supply of oxygen almost 45% of the influent ammonium might be oxidized anoxically.In this Research Topic, we would like to improve our understanding of anammox processes in removing nitrogen. The anammox process is a combination of two treatments: a partial nitrous acid conversion process in which ammonia nitrogen (NH 4-N) is converted into nitrite nitrogen (NO 2-N), and an anammox process in which the anammox reaction is used to remove the nitrogen. Pre-treatment processes for removing organic matter or suspended solids can be added as necessary, depending on the properties of the wastewater being treated. The Anammox® process is a biological treatment system for removal of ammoniacal nitrogen.

After si … Study on one-stage Partial Nitritation-Anammox process in MBBRs: a sustainable nitrogen removal v SUMMARY IN SWEDISH Under det senaste decenniet har flera nya och kostnadseffektiva biologiska kvävereningstekniker utvecklats. Upptäckten av anaerob ammoniumoxidation (Anammox), för ca 15 år sedan, har resulterat i Increasing information supported that achieving high-rate mainstream deammonification through two-stage partial nitritation (PN)-anammox process should be a better option than through single-stage process.

8 Mar 2016 Anammox Process. Anita Mox is a moving bed biofilm reactor for treating wastewater with high ammonia concentrations (200 to 2,000 mg/L).

The anammox process is one of two microbial processes that release fixed nitrogen from the environment as dinitrogen, the other being denitrification. Anammox bacteria have been discovered in many environments, including suboxic marine zones, coastal sediments, lakes, and wastewater treatment plants .

2002, Schmidt et al. 2003). 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).

Compared to conventional nitrifi The Anammox process was operated as a granular sludge SBR-process. More than 80% of the ammonia was converted into dinitrogen gas at a load of 1.2 kgN/m 3 per day. Planctomycete-like bacteria dominated the mixed community of the Anammox reactor, and only a small percentage of the population consisted of aerobic ammonium-oxidizing bacteria. 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.
