Type Plate

Inside the shaft system, there is a type
plate attached underneath the manhole
cover (Fig. 8). The following data needs
to be copied from there and kept readily
available for the purpose of maintaining
the operating log and dealing with queries
of all types.
Plant type
Nominal size
Sludge trap capacity
Separator capacity
Grease storage capacity
Year of construction

Operating and maintenance instructions

Grease separators must be operated
free of backflow.
The only kind of water that may be sup-
plied to grease separator plants is grey
water that is to have organic oils and
fats separated from it.
Grease separators must be connected
to grey water drains.
To avoid deposits, the inlet lines must
have a gradient of at least 1:50.
Grease separator plants and their inlet
and outlet lines must be adequately
ventilated to avoid putrefaction, depo-
sits and functional impairments. For
this purpose, the inlet line must be
ventilated through the roof. All connec-
ting lines with a length of more than 5
m must be ventilated separately. If the

inlet line is more than 10 m long, it is
either necessary to ventilate additional
connecting lines separately or for the
inlet line to be ventilated directly at the
grease separator plant using a vent
stack through the roof.
Proper functioning of the grease sepa-
rator can only be ensured in the long
term if it is emptied on time and consci-
entiously maintained.
Plants must be readily accessible so
that the disposal process can be per-
formed without any problems.
In general, a sampling facility should
be provided downstream of each se-
parator.
