2024-11-05 | Wastewater treatment plants of the future: carbon harvesting and energy recovery (Nijhuis Saur Industries, Doetinchem)

In the future, municipal wastewater treatment plants should become energy and carbon neutral. To meet this requirement, a process is required in which most of the organic pollution is converted into energy, instead of being oxidized and lost to the air. This can be achieved by using a digestor producing energy, instead of an aerobic bioreactor oxidizing COD. This digester should be operated with a concentrated feed and therefore, the wastewater treatment plant of the future will start with the concentration or harvesting of COD for the digester.
