The biological plant is monoblock, tricameral, one compartment adjacent to the other, one for sedimentation and the other for digestion, and the third for final sedimentation.

The sedimentation compartment, physically separated from the digester, is connected to it only through the passageway from the extreme side of the sedimentation.

Black water reaches the sedimentation, whereby the specific weight difference between water and sedimentable material produces sedimentation that precipitates in the anaerobic digestion zone.

Sediment-free water passes through the outlet pipe, while sediments remain on the bottom of the tank and undergo an anaerobic digestion process, which partially mineralizes the organic matter.

The septic tank will be regularly vacuumed by specialized firms.

Vacuum period 2-4 years.
