10. Operating instructions
Basically only substances with the characteristics of domestic wastewater may enter the sys-
tem.
Biocides, toxic substances or substances which are not biocompatible or biodegradable must
not enter the system because they cause biological process problems. The following are not
permitted:
rainwater from roofs and yards
infiltration water (e.g. drainage water)
liquid or solid residue from keeping animals
commercial or agricultural wastewater, unless it is comparable to domestic wastewater
chemicals, pharmaceuticals, mineral oils, solvents
cooling water
solids in the form of food waste, plastics and hygiene articles, coffee filters, bottle tops
and other domestic items
milk and milk products
water discharged from swimming pools
large volumes of blood
If discharging larger volumes of grease or plant-based oils, we would recommend pre-cleaning
the wastewater containing the greases/oils in a grease separator upstream of the wastewater
treatment system (caution: faeces must not be allowed to enter the grease separator!).
