3. Construction and functional principle
The small wastewater treatment system is fully biological and works according to the retention process
with long-term aeration. The system is made up of an aerobic stage. A scum board is used to split this
stage into a coarse substance chamber and an activation chamber. The chambers are connected to one
another in the bottom section. During this process, therefore, all domestic sewage is immediately exposed
to aerobic wastewater treatment. The entire system is aerated due to compressed air being blown in and
the sludge activated as a result of this biologically cleans the wastewater.
