1.1. Application
Oils and greases in wastewater are not allowed to be drai-
ned into public wastewater pipes / sewers and also not into
to lakes / rivers. Oil and greases in wastewater pipes can
collect on the interior walls causing a reduction in the cross
sectional area of the pipe and eventually pipe blockage. In
addition, over time the collected grease begins to decompo-
se and turn acidic which can lead to odour nuisances as well
as the corrosion / degradation of the drainage pipes and sy-
stem.
Without grease separators, the oils / greases will collect on
the surface of ponds / lakes as well as wastewater treatment
collection ponds causing reduction of oxygen access to
these waters. DIN 1986 Part 1 requires that harmful sub-
stances are retained. For this reason, grease separators in
accordance with DIN 4040 must be provided and the grea-
se disposed of appropriately.
1.2. System Description
Separator function
The special feature of the Type „SE“
grease separator for self disposal of
waste is its method of disposal.
While conventional separators must
be emptied completely and shut
down while this work is carried out,
in the case of the „SE“, only the ma-
terial which has been separated out needs to be disposed
and is drained off via discharge pipes into exchangeable bar-
rels. The grease separator can be emptied any time without
having to interrupt the process. The separated material is in
smaller quantities and is in a fresh state due to the fact that
the sludge and grease is emptied multiple times per week.
Barrels which have been filled are replaced with empty ones.
Displaced air from the separation system is fed back into the
separator meaning that no problematic odours are released
during operation / disposal. If the grease solidifies, it can be
returned to a liquid state via the separator’s heated cover.
During the heating process self cleaning takes place – as the
grease liquefies any particles / solids settles out of the grea-
se layer and settle to the base of the tank. Sediments which
settle out in the separator tank are pumped back to the slud-
ge trap via a circulation system.
