Leading the biotech revolution
in wastewater and biogas


Looking for a sustainable and cost-effective nitrogen removal system? With ANNAMOX® for ammonium removal from effluents and ammonia from waste gas, you can save up to 60% on operational costs compared to conventional systems, while reducing CO2 emissions.

What makes ANAMMOX efficient?

The ANAMMOX® conversion is an elegant shortcut in the natural nitrogen cycle. Anammox bacteria convert ammonium (NH4 +) and nitrite (NO2 -) into nitrogen gas. Paques developed the nitrogen removal system for commercial purposes in cooperation with Delft University of Technology and the University of Nijmegen. Since the first full-scale plant started up in 2002, many other ANAMMOX® plants have been implemented worldwide.

Applications of ANNAMOX®

The nitrogen filter system ANNAMOX® process can be used for the removal of ammonium from nitrogen rich effluents, which for example can be found in:

  • Municipal wastewater treatment (sludge rejection water)
  • Organic solid waste treatment (landfills, composting, digestion)
  • Food industries
  • Manure processing industry
  • Fertilizer industry
  • (Petro) chemical industry
  • Metallurgical industry
  • Semiconductor industry
