WWTP in Baden-Wurttemberg

Background

The aim of the waste water treatment plant was to increase the gas yield as well as to reduce the amount of sludge and as a result of that the disposal costs.

Result

A batchtest showed an increase of the gas yield of the treated thickened surplus sludge of 11.5%.

WWTP in Moscow

Background

The aim of the waste water treatment plant was to increase the gas yield as well as to reduce the amount of sludge and as a result of that the disposal costs.

Result

An independent laboratory experiment showed an increase of the gas yield of the surplus sludge up to 17%.

WWTP in Switzerland

Background

Different disintegration experiments have been carried out on a waste water treatment plant in Switzerland for investigating the efficiency on the aerobic decomposition of several substrates.

Result

Kitchen waste was used for one of the experiments. There an efficiency increase of more than 9% could be pointed out.

1300 kW Biogas plant in Lower Saxony

Background

This biogas plant had the aim to save substrate as well as to increase the biogas yield.

Result

The carried out batch test showed an increase of efficiency of the ultrasound treated samples in comparison to the untreated samples of 13,5%.

560 kW Biogas plant in Freiburg/Elbe

Background

The biogas plant was built to expand the crop rotation through the plantation of maize and grass. The ultrasound disintegration plant of Weber Entec shall increase the gas yield of the used substrates.

Result

The laboratory test yielded to an increase of the treated samples in comparison to the untreated samples of more than 10%. Note, that the sampling was carried out two month after installation and commissioning of the disintegration plant. It can be assumed that the real increase is higher than the measured increase.

513 kW Biogas plant in Lower Saxony

Backround

This biogas plant required to save substrate and increase the biogas yield.

Result

A lab test showed an increase of the biogas yield of more than 15%.

663 kW Biogas plant in Mecklenburg-Western Pomerania

Background

The aim of the plant was to increase the gas yield.

Result

The comparison of the treated and untreated samples showed an increase of efficiency          of 14%.

Biogas plant in Rhineland-Palatinate

Background

The biogas plant wanted to save substrate and increase the gas yield.

Result

An independent laboratory confirmed that the gas yield was increased of more than 20% and by that the efficiency was improved.

Biogas plant in Saxony

Background

This biogas plant mainly uses maize and manure. The aim was saving substrate and increasing the gas yield.

Result

With the disintegration plant of Weber Entec the gas yield was improved significantly. The laboratory verified a more than 21 % higher  biomethane production.

Biogas plant in Mecklenburg-Vorpommern

Background

The biogas plant had the aim to increase the gas production as well as to save substrate.

Result

After installing the ultrasound disintegration plant an efficiency increase of more than 22% was measured.

Biogas plant in Saxony-Anhalt

Background

This biogas plant mainly uses maize silage.

Result

In a batch-test an increase in efficiency of more than 12% could be showed.

1 MW Biogas Plant Magliano

Background

This biogas plant uses a wide range of substrate mixes. These include sorghum, maize silage, broad beans, oats, clover, and ryegrass.

Result

An independent laboratory demonstrated an increase in efficiency of 11.4% for the treated trial in comparison with the untreated trial. A further test even indicated an increase of more than 13%.

Biogas Plant Vreden

Background

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.

Result

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.

250 kW Biogas Plant Rastdorf

Background

Because of his difficult substrate mixture, which had reduced fluidity caused by the high portion of horse manure and of intermediate crops, the plant operator decided in favour of a preparation step using a disintegration plant from Weber Entec.

Result

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.

Biogas plant Jena 1 and 2

Background

In 2011 Weber Entec was asked to prove the efficiency of the Smart DMS ultrasonic disintegration plant at one of the two identical biogas plants in Jena. In the second biogas plant, the cell opening-up technology of a competing product was tested in parallel; this was based on the electrokinetic process. This large-scale, long-term trial was observed by the State Agricultural Institute of Thüringen. The Institute in turn engaged Eurofins for analytical observation of the trial.
Both plants have an output of 700 kW, and are fed with maize (70%), goat dung, and other agricultural waste products.

Result

After the 11 month trial, an increase in biogas yield of more than 11%, in other words annual savings of about 80,000 euro, was demonstrated to Weber Entec. For further information, please refer to the detailed final report from Eurofins (see PDF Download Button).

500 Nm³/h Biomethane production plant in Mühlacker

Technology

The plant generates bio-methane from renewable raw materials. In order to increase the plant’s efficiency, it was equipped with Weber Entec’s ultrasonic technology.

Result

In the batch test, the ultrasonically treated sample showed an increase of 13.2% when compared with the untreated sample.
