Application of Ultrasound Disintegration )) Biogas plants WWTPs» 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 disposed» Consistent decrease of viscosity» Improved decanting» Elimination of foam / fibrous bacteria WEBER ENTEC 2016 page 3
Effects of the ultrasound disintegration )) Increase of biogas yield Decrease of sludge to be disposed Decrease retention time in fermentation Decrease of energy consumption (pumping, stirring) Increase of de-waterability 10-25 % 10-25 % 10-20 % 5-20 % 5-20 % WEBER ENTEC 2016 page 4
Physical principle Cavitation )) 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 Source: L.Crum, University Washington, Seattle WEBER ENTEC 2014 page 5

Implementation UPWRP's Full Scale Ultrasonic Hydrolysis Plant )) The performance of the plant shall be verified through a series of batch tests. Over a period of eight weeks, every week a series of samples shall be taken and a batch test shall be performed. In order to measure the performance, a series of untreated samples (control) are being compared to a series of treated samples. The target is and improvement of biogas yield of about 21%. The following graphs show some samples of the performed batch tests: WEBER ENTEC 2016 page 16
