4.5 Separating Function
The separator separates water and solids
from the uncleaned oil. Water normally
leaves the separator through the water
outlet. During sludge discharge, solids
(sludge) and water are removed through the
discharge ports.
4.5.1 The liquid balance in the bowl
The liquid levels in the bowl depend on many
factors (bowl geometry, liquid densities, flow
rates etc.). To get a picture of how the liquids
are distributed in the bowl, imagine that the
bowl is at standstill and turned 90° (only
influenced by gravity). The bowl can now be
compared with a settling tank:
