|There were 3 of these screw pumps ,each of them is able to pump 800l per second and has a diameter of 2 m!|
|looks pretty ugly at this stage. The brown color comes from the bacteria|
|this one is also aeration basin with bacteria in it , but air is pumped into it at the bottom so the bacteria can dissolve|
other organic material
In the second stage water and the bacteria-mud get seperated in round sedimentation basins.
|The basins are funnel shaped so the mud falls to the bottom|
and can be exhausted
At the end there are again some round sedimentation basins.The warter that leaves the facility is to 97-99% clean.The excess bacteria mud and the incoming organic material is later on collectedin huge digester towers
to produce methane gas.
|We even saw a fish in the last sedimentatin basin|
