Beschreibung
In a hut with 5000 overnight stays per year, the disposal of wastewater is a challenge in addition to the energy requirement. To the right below the path you can smell and see the biological wastewater treatment.
What you leave behind in the quiet place first goes into the pre-clarification below the four sinkhole covers. In the primary clarifier, the wastewater flows so slowly that solids and sludge from the wastewater settle.
The wastewater then enters the trickling filter. The 7-meter-deep, gravel-filled pool is located under the boards. The wastewater is sprayed finely over the gravel and flows slowly over the gravel stones. The microorganisms living on it absorb the dissolved pollutants from the water as food and thus purify the wastewater.
In the secondary clarifier under the round metal lid, the microorganisms carried by the trickling filter settled at a slow flow rate. The treated wastewater is discharged via the overflow into the meadow. Once a year, the sludge from pre- and post-clarification is removed, dried and distributed underneath the plant.
Now go to the last interesting place "Ice melting and brazen shepherds" on the terrace. There you will have time to recharge your batteries and observe and listen to all kinds of things!
