AAT is taking part in the EU research project SYMSITES which is about circular economy and energetic utilisation of industrial wastewater. AAT built a hydraulic digester in pilot scale for the Austrian Ecosite.

Project data:
- Commissioning: 2023
- Substrates: flotation sludge, membrane retentate and slaughterhouse waste
- Daily wastewater input: 4 m³
- Daily gas production: 6.6 m³

This pilot plant was specifically developed and built for an industrial company to take wastewater treatment to a new level.

The pilot plant at a glance:
- A 20-foot container houses the control system, the buffer tank, the pump technology, the gas technology and the centrepiece of the plant: a hydraulic digester with a capacity of 2.8 m³.
- A 10-foot container serves as a gas storage.

The energetic utilisation of industrial wastewater is not only an important step towards sustainability and environmental protection, but offers also valuable perception for the future of wastewater treatment.
