DEMON®: low cost and more energy efficient

Wastewater treatment plants must comply with ever stricter discharge standards, in particular in respect of nitrogen. Sweco was involved in the development of an innovative treatment method which is not only less expensive but also more energy efficient than conventional techniques. DEMON® – short for ‘DEamMONification’ – Saves 60% on aeration energy, without the use of chemicals.

The conventional method of nitrogen removal (nitrification/denitrification) is energy intensive and requires a carbon source. DEMON® requires no carbon source, thereby eliminating the need to use chemicals. The DEMON® process ensures low energy consumption for a lower CO2 emission, thus making a real contribution to sustainable business practice. The technology is robust and is a proven technology, with more than 70 references world wide.
