Control of sludge content
Dismantle the separator and
measure the thickness (A) of
the sludge collected on the bowl
wall. The thickness should never
exceed 10 mm.
If the interval between bowl
cleaning is too long, this can
result in a sludge cake that is
hard and difficult to remove. Too
long interval can also result in that
sludge enters the disc stack and
hinders separation. Oil overflow
and vibration can also occur.
When cleaning very contaminated
oil, bowl cleaning every 20 - 30
minutes could be necessary.
