Important results from the project
The project has resulted in a control strategy for start-up and optimized operation for the biological nitrogen removal process DeAmmon (R). It has enabled PhD studies for an engaged Process Engineer at Purac.
Expected long term effects
The developed control strategy has been implemented in a full-scale plant. A scientific evaluation has shown a 90% reduction of nitrous oxide emissions in this particular plant, where the control strategy also had a positive impact. The CONAN project has contributed to a strong competence development at Purac in the purification of nitrogen-rich wastewater from biogas plants. Purac has taken a step forward to export the technology, where the project contributed to a risk minimization through new knowledge about the applicability of the technology.
Approach and implementation
The project has resulted in a pilot plant where various control strategies have been tested using full-scale equipment and substrates. This has formed the basis for a full-scale plant, that has been designed and built in parallel with the CONAN project. In the full-scale plant, verifying measurements have been carried out and the operation has also been optimized through continuous remote monitoring of the plant, thanks to the implemented software.
