Biogas plants More energy from biomass by ultrasound

Ultrasound systems on biogas plants Areas of use and advantages secondary fermenter storage tank Integration of ultrasound technology into biogas plants Ultrawaves‘ ultrasound systems are used in agricultural biogas plants However, the biological anaerobic degradation process takes place to intensify anaerobic biological degradation of all kinds of added very slowly, as the solid biomass is difficult for the bacteria to break biomass materials, such as, renewable raw materials, maize, green down. The first step in the degradation chain is the so-called hydroly- waste, slurry, etc. This results...

micro-organisms is stimulated. Sonication also causes an increase in the interface between the liquid and solid phase (particles and flocs disintegrate), which facilitates enzymatic attack. Further energy supply also destroys the walls of plant and bacterial cells and therefore results in the release of the dissolved organic cell contents, which are in turn very readily degraded by fermentation. The end effect is an intensified digestion process with further degradation of the organic substrates and increased biogas production. Therefore, by using ultrasound, on the one hand more biogas can be...

Practical results Case study: Bordesholmerland biogas plant In December 2007, the first biogas plant in Germany was operated with Ultrawaves ultrasound technology. Today we have successfully substrate line 2 with ultrasound biogas line 2 with ultrasound 7000 equipped many more biogas plants with our ultrasound technology. standard ultrasound reactor. The test started in May 2011 with the objective of using less substrate while maintaining the same biogas production (6,150 m³ per day per line). 36 m³ per day of the second- lines are operated, one of which (line 2) has been equipped with our ultrasound...
