Advices for taking biogas plant samples


representative sample ( pre-tank, secondary fermenter, fermenter residues) = composite sample of each

Pre-tank, economic fertilizer       

Before taking the samples you should homogenize the material with a mixer.
When possible, take out  various samples from different parts of the tank, mix well and fill it into one container.

dung, faeces       

You should take different single samples from diverse areas of the dunghill. Lay
bare outer dunghill layers.


Before taking the sample you should drain some fermenter material, than mix the fermenter content and take the sample to be examined.

Sample quantity:  500 g – 1000 g of each composite sample

Please note, fill the sample bottle only ¾ because it is possible that the material produces gas.

Send the samples under cool conditions in our lab (enclose frozen thermal bags)!
