Inefficient operation WWTP

Inefficient operation waste water treatment plant

The operations of the WWTP can be more efficient.

At a WWTP the ammonium content in waste water is reduced to an acceptable amount. This process costs energy and chemicals. In addition, rejection water originating from sludge dewatering provides a major contribution to the ammonia load of the WWTP. There is a need for a more effective way to reduce the ammonium content of ammonium-rich water streams.



With DEMON technology, ammonium is cost-effectively removed from waste water from sludge dewatering with the use of a minimum amount of energy and chemicals. The use of this technology results in lower sludge production and in energy and chemical savings.

Demon WWTP Amersfoort


  • With the use of DEMON technology it is not necessary to add an organic carbon source to remove nitrogen.
  • DEMON technology is easy to implement at existing WWTPs.
