7. Operating Notes

Essentially, the system should only be supplied with materials that correspond to domestic wastewater in
their characteristics.
Biocides, materials with a toxic effect or materials that are not biologically compatible or degradable must
not enter the system, as these lead to biological process problems. The following, in particular, should not
be introduced into the system:

Rainwater from roofs and courtyards,

Extraneous water (e.g. drain water)

Residues from livestock in solid or liquid form,

Industrial or agricultural wastewater, as far as it is not comparable to domestic wastewater,

Chemicals, pharmaceuticals , mineral oils, solvents,

Cooling water,

Coarse materials in the form of food scraps, plastics and hygiene products, face wipes, coffee fil-
ter papers, bottle caps and other household items,

Milk and dairy products

Drain water from swimming pools,

Large amounts of blood.
In the case of large amounts of fats or vegetable oils, it is recommended that the fatty wastewater is pre-
treated in one of the grease traps upstream of the wastewater treatment system (Caution: No faeces may
be introduced into the grease trap!).
