Paques ANAMMOX - Nitrogen Removal System
ANAMMOX is a sophisticated nitrogen removal system developed by Paques, representing a major advancement in wastewater treatment technology. Introduced initially in 2002, it integrates partial nitritation with the ANAMMOX process, facilitating a more efficient conversion of ammonium (NH4+) and nitrite (NO2 -) into nitrogen gas (N2). This innovative process employs naturally developed granular sludge, optimizing conditions for microbial synergy, thereby enhancing its operational efficiency. ANAMMOX is particularly beneficial for removing ammonium from nitrogen-rich effluents commonly encountered in industrial and municipal wastewater treatments. Compared to traditional methods, it offers substantial benefits, including reducing operational costs by up to 60% and minimizing CO2 emissions. It is a proven technology developed in collaboration with leading universities, and continues to transform wastewater management.
Since Paques pioneered the first biological nitrogen filtration system in 2002, ANAMMOX has become the world’s most used nitrogen removal system. You can also profit from the most efficient nitrogen removal system on the market: ANAMMOX offers a treatment capacity of over 160.000 kg nitrogen per day.
Why choose ANAMMOX as your nitrogen removal system?
The ANAMMOX conversion is an elegant shortcut in the natural nitrogen cycle. Anammox bacteria convert ammonium (NH4+) and nitrite (NO2 -) into environmentally neutral nitrogen gas (N2).
The currently patented Paques one-step ANAMMOX technology combines partial nitritation (conversion of ammonium into nitrite) with the ANAMMOX process. The ANAMMOX process operates with naturally grown concentrated granular sludge in which optimal conditions for microbial synergy are created.
The ANAMMOX® process can be used for the removal of ammonium from nitrogen rich effluents. It is often applied after anaerobic treatment of sludge or wastewaters.
For example in:
-
Municipal wastewater treatment (sidestream)
- Sewage sludge reject water
- Co-digestion reject water
- Thermally hydrolyzed sludge reject (THP)
-
Industrial wastewater treatment
- Food industries
- Fermentation industry (e.g. yeast, alcohol, pharmaceutical)
- Organic waste residue digestion
The main potential advantages of the ANAMMOX® process as compared to traditional biological treatment are:
- Lowest aeration energy consumption (< 1kWh/kgN removed)
- Lowest excess sludge production
- Smallest space requirement (concentrated active granules biomass)
- No need for addition of external carbon source
- Production of valuable granular sludge as sole by-product.
- Reduced carbon footprint (CO2 consumption - anammox bacteria do not emit N2O)
