ANAMMOX®

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.

Applications of ANAMMOX®

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

Advantages of the ANAMMOX® process

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)
