Anammox®

Anammox®

The Anammox® process removes nitrogen from wastewater in a cost effective way. Anammox® offers great advantages compared to conventional nitrogen removal processes including:

  • Power consumption is reduced by up to 60% as compared to conventional nitrification/denitrification methodology;
  • No additional carbon source needed;
  • Overall operational cost reduced by up to 90% compared to conventional nitrification/denitrification methods;
  • CO2 emission reduced by approximately 88%;
  • Plant foot print ~50% of conventional plants;
  • Proven in full scale plants.

This innovative process is patented and supported by Paques BV of The Netherlands.

The Process:

Nitrogen Cycle Custom Annamox Granule

Anammox Bacteria:

The Anammox® process (for: Anaerobic ammonium oxidation) removes ammonium without oxygen and with nitrite as the electron acceptor. The cost of conventional ammonium removal via nitrification-denitrification from sludge reject waters is mainly associated with aeration-cost and the addition of an expensive electron donor (e.g. methanol). The Anammox® process provides an alternative for the nitrification, with no requirement for an extra electron donor. The (generalized) overall reaction of the One Step Anammox® process is:

2NH4+ + 1.5O2 ? N2 + 2H+ + 3H2O

Also, the emission of greenhouse gases is enormously reduced using the Anammox® process. The overall CO2 emission of a wastewater treatment plant can be reduced by approximately 88% because the Anammox® process itself consumes CO2. Furthermore, the production of nitrous oxide (N2O) that can easily be formed as a by-product of conventional denitrification is not emitted using the Anammox® process.
