On September 15, we were on the open day at the biogas plant in Techentin. Our ultrasound disintegration plant DesiUS is installed there for three years now. We talked about the successfully long-term evaluation there and could present the ultrasound disintegration plant to interested visitors.
Even the press was there (see attached Press article).
Jühnde is the first bioenergy village in Germany and even worldwide. Heat and power demand is produced by a renewable energy biogas plant as well with photovoltaik technology.
It was founded in 2005 and attracted the attention of the world with the unique idea. Until now, 30.000 interested visitors came to Jühnde. Just in Germany 150 villages followed this example.
After 10 years of operation it was time to update the plant on the latest state of technology and to make the most of the opportunities of the EEG. The company ETS Economic Trading Solutions GmbH developed a sustainable end-to-end concept called “Jühnde-Bioenergiedorf 2.0″. The first step of the overall concept was the installation of the ultrasound disintegration plant from Weber Entec in September 2015.
Increased efficiency thanks to Weber Entec
Weber Entec was hired to to meet the new requirements and to get the optimum out of the substrate. The plant technology effects a better exploitation of the used substrates resp. a higher gas production, it improves the viscosity of the biomass, decreases the energy consumption for stirring and reduces the wear on all pump- and stirring aggregates.
Verification of the guaranteed success
Because of the strong qualitative and quantitative fluctuation of the substrate-mixture of the biogas plant the plant operator required two batch tests for proof of success. One has to be performened at an independent laboratory and the other one directly at the biogas plant in a mobile laboratory.
Substrate was taken directly after commissioning, both before and after the ultrasound disintegration plant. After that the methane gas production was measured and the increase in efficiency determined by comparing of the untreated and treated samples.
Both experiments showed an increase of the methane gas production of approx. 15% for the at the optimum set ultrasound samples. So the guaranteed performance increase was clearly surpassed. Picture 1 showes the methane gas curves for the untreated and with three different ultrasound treated samples.

Proof of long-term success of the ultrasound disintegration plant
In June 2016 the open house day will take place. For own interest and to have the positive results reconfirmed again, the plant operator instructed a new bacht test 5 month after commissioning the disintegration plant. He also wanted to find out, if the effect of the disintegration plant is of lasting existence. The batch test showed an increased yield of the ultrasound treated samples of 15.9% in comparison to the untreated one. These results show the long-term success of the ultrasound disintegration plant.
Conclusion of the operator
Mr. Fangmeier, board member and speaker of the biogasplant Jühnde:
„The biology never has been as active as now. The flow properties are significantly better after installation of the ultrasound disintegration plant.“
Our partner United Engineers in Singapore won a tender for the Ulu Pandan waste water treatment plant, for substrate digestion of the surplus sludge. A plant with 16 BioPush ultrasonic reactors was installed. This brings Weber Entec’s disintegration technology into use in Singapore for the first time.
Our colleague flew to Singapore for commissioning our plant. He guided the staff in Singapore in for example the Siemens PLC.
On the following picture the traffic lights on the control panel can be seen, which reproduces the operating situation of the plant.
… and again another ultrasound disintegration plant was installed!
From 27 to 29 January Weber Entec presented the innovative products and developments on the Annual Conference and Trade Fair in Bremen.
A first impression of the exhibition show the following pictures:
The second fair of the year gave us the chance to visit the beautiful Italy. From 23 to 25 February we presented our technology next to 97 other companys. Weber Entec offered a one-hour workshop with the topic: „Increasing biogas efficiency by ultrasound“.
Even the italian TV crew drew attention to us:
From 2 – 3 June 2015 the annual biogas innovation congress in Osnabrück took place. The focus this year was on optimizing the operation of agricultural biogas plants.
Mr. Grams gave a talk about the efficiency of the ultrasound disintegration which aroused a great interest among the participants.
After the presentation many conference members followed the invitation from Mr. Grams to our stand to exchange experiences with a satisfied user of our technology – from operator to operator.
The world’s largest trade fair for agricultural machinery and equipment took place from the 8 to 14 November. It started with two preview days, which were intended primarily for visitors from agricultural machinery dealers, top investors and the trade press. The following five days gave a wide range of conferences and forums to the visitors.
The last fair in this year brought us to China, or more precisely Guangzhou. There was the BioEnergy Conference from the 15. – 16. December. The two days Sino-German Conference focused on Policy, Financing Support, New Technology and Extension.
Since 2011, the AMPTS II system developed by the Swedish manufacturer Bioprocess Control has been marketed in Germany, Austria, Switzerland, and the Netherlands exclusively by Weber Entec. AMPTS stands for Automatic Methane Potential Test System. In particular, the “fully automatic” characteristic convinced Weber Entec so strongly, that the company itself uses two of these devices in its own laboratory. The AMPTS II is the fastest and most precise system anywhere in the world for carrying out a batch test. Since 2011, every disintegration plant installed by Weber Entec has been accompanied by an extensive batch test. This allows the ideal operating point, adapted to the characteristics of the specific biogas plant, to be determined and then configured. Since 2011, Weber Entec has continuously extended its research department, and to date has assessed more than 400 substrate samples through batch tests.
You will find more information on the AMPTS II under Laboratory Fermentation.
