The process water plus operation and domestic wastewater part-streams make up the
entire wastewater. Cooling water and rainfall water are disposed of in the separation sys-
tem. Origin and specific amount of the process water, as well as the single wastewater
part-streams are discussed in Chapter 3.2.
The amount of process water is based on the natural water contents of the raw
material and cannot be influenced.
Only the spray water can to a low degree be influenced. Experience shows that in larger
plants the specific consumption related to the amount of raw material is lower.
