Title: Development of the Demon process for an energy-autonomous wastewater treatment facility
The development and implementation of the Demon® control strategy for ammonia removal at the wastewater treatment plant in Strass in Tyrol (Austria) for the first time realized stable operation of an advanced municipal treatment plant that produces an energy surplus. This makes a significant contribution to energy efficiency and process optimization of the plant. The surplus of 8% is fed as renewable energy into the public grid, making a wastewater treatment plant a power generator. Additional installations in Europe and demonstration projects in New York and Washington confirm the success of the project.
