The Wave-Box is a new PRE development for the high-power digestion of fibrous substrates. Using a reversible pump, the digester substrate or digestate is continuously and optimally brought through a cleverly designed system of pipes into the effective range of ultrasound-emitting “sonotrodes”. The control unit allows the user to adjust the flow rate, pressure, flushing cycles etc. The Wave-Box operates in a bypass circuit and can be integrated into the PRE high performance digester and the PRE Kombi Hydrolysis unit or can be retrofitted to biogas systems.
The main component is the newly developed high-power ultrasound system. Other components include a volumetric flow meter, pressure and volume controlled pumps, sensors, flushing pipes as well as a self-optimising and self-monitoring control unit.
