Origin of solids

Origin of solids - Wastewater

Domestic wastewater originates from private households and similar facilities. These solids consist of 80-90% organic matter, such as food particles, grease, feces, hair, paper, etc. [Godeh2002] [ATV96:2007] [ATVDVWKM 369:2003].

The remaining portion consists of mineral solids that result from the incorrect disposal of household waste such as cat litter.
