Disposal intervals:
The fuel / oil collected in the separator should be collected /
disposed when the level has reached 80% of the maximum
storage capacity. Disposal of collected sludge in the base of
the separator should be collected / disposed when the level
has reached 50% of the maximum sludge storage capacity.
Important: Timely disposal of the separator is mandatory to
insure proper function and operation of the separator.
A licensed disposal company should be contracted to handle
disposal of the separator. Disposal should take place when
little or no wastewater is entering the separator.
Emptying intervals:
The light fluid retained in the separator must be removed at the
latest when the quantity of separated light fluid reaches 80%
of the maximum storage quantity, or the level is below the
retained volume. For separators simultaneously or exclusively
used for the drainage of systems or areas where light fluids
are handled (e.g. fuelling areas), the retained volume required
under state regulations must also be provided. The separated
light fluid must also be removed at levels below this retained
volume if the quantity of separated light fluids has not yet rea-
ched 80 % of the maximum storage quantity.
The disposal of the sludge contained in the sludge trap must
be removed at the latest when the separated sludge quantity

reaches half of the sludge trap volume.
Note: Light fluids and sludge must be removed as speci-
fied above in order to ensure the correct operation of the
system.
For this reason, a disposal contract should be concluded with
a specialist disposal company. The disposal work should be
carried out if possible when the system is not in operation.
Expected disposal volumes in accordance with the filling level
can be estimated by means of the following table.
The figures contained in the table are approximate figures only
for the purposes of estimating quantities when contracting a
specialist disposal company.
