Final report only available in German
A novel method for the determination of the particle size distribution is adapted for the optimization of feedstock pre-treatment and exposure of the fluid phase of biogas processes to ultrasound. The solution shall be integrated easily in existing plants and the online measurement shall be analyzed and applied independently from other monitoring tools. The method will be applied in three industrial-scale case-studies.
Applying this approach, an increased substrate flexibility and operational efficiency is envisaged. Therefore, the ultrasound-based disruption of particles shall be monitored with laserlight-based back-reflection so that a real-time in situ optimization becomes feasible.
Set up of a lab-scale experimental rig and application of the coupled disruption and analysis method in experimental series planned with statistical experimental design. Transfer into industrial scale so that the ultrasound- and analysis technique is applied in a bypass. An optimization of the ultrasound-based disruption based on lab experiments is conducted. Finally, an economic evaluation will be performed based on the gained data.

The hardware of sensors will be modified for their application for the measurement of the particle size distribution in the liquid phase of anaerobic digesters. Additionally, software will be modified to allow to distinguish between biologically active and inactive particles based on their back-reflection features.
Development and construction of a circulating ultrasound system, which includes the disruption of agglomerates and biomechanical material to optimize the liquid phase in digestion processes.
