Aim was the maximum use of the rated power.
The digester load could be increased, the rated power increases by 20 %.
The aim was increasing of the efficiency of the biogas plant.
An independent laboratory verified an increase of the methane gas production of the treated samples in comparison to the untreated ones of 15,7%.
Because of his difficult substrate mixture, which had reduced fluidity caused by the high proportion of horse manure and of intermediate crops, the plant operator decided in favour of a preparation step using a disintegration plant from Weber Entec.
The viscosity decreases perceptibly, the substrate is more homogeneous, and the addition of enzymes and trace elements has become superfluous. A lab test indicated an increase in efficiency of 20.5% in comparison to the untreated control.
The combined heat and power plant (CHP) was working at only 75% load (190 kW). The aim was to obtain a 100% load for the CHP. In addition, maize silage was to be successively replaced by more difficult substrates such as grass.
Even just three months after commissioning the ultrasonic disintegration plant, the CHP achieved a load of 230 kW. In the meantime, the CHP is running at full load.
