BIOGAS PLANTS WWTPs
APPLICATION OF ULTRASOUND DISINTEGRATION
▶ Increase of biogas production
▶ Reduction of feed stock at equal
performance
▶ Acceleration of organic degradation
▶ Consistent decrease of viscosity
▶ Reduction of pump- and stirring energy
demand
▶ Increase of biogas production
▶ Reduction of sludge to be diposed
▶ Consistent decrease of viscosity
▶ Improved decanting
▶ Elimination of foam / fibrous bacteria

Direct comparison of the untreated and treated
sample just after operation of the disintegration
machine
After BioPush Treatment:
▶ Reduced viscosity
▶ Improved flow properties
▶ Decrease of energy consumption
(pumping, stirring)
▶ More stable biology
▶ Higher proportion of difficult
substrate usable (grass, manure,…)Untreated sample Treated sample

PHYSICAL PRINCIPLE – CAVITATION
21.11.2017 Company presentation8
Ultrasound liberates enzymes and shears up the substrates
Physical principle: Cavitation
Short term local µm-radius
▶ Extreme high temperature (up to 5.000 C°)
▶ Extreme high pressure (up to 1.000 bar)
▶ Extreme high acceleration Shear forces
Multiply enlarged cavitation bubble
in the moment of implosion
