2. General
2.1 Area of application
The separators are intended for use under specified condi-
tions, see the Chapter "Installation and assembly", for instal-
lation underground or below the foundation slab in well-ven-
tilated areas.
The stability of the tank is only guaranteed for its own weight,
for transport and for the described installation in accordance
with the intended use (e.g. load class, road construction build-
up). Additional loads from single or strip footings or other exter-
nal actions must be avoided. If such actions are to be expected,
it may be necessary to take special measures.
2.1.1 Oil-fuel separators to Separator System B
The separators can be used:
a) for the treatment of rainwater contaminated with light
fluids from surfaced areas, e.g. filling stations, oil storage
and handling areas, parking areas and streets in water
protection areas
b) as a retaining system for light fluids from systems and
areas where light fluids are handled, e.g. filling stations,
oil storage and handling areas
c) for preliminary separation of light fluids from waste water
before further treatment in subsequent internal waste
water treatment plants.
In cases a) and b), the discharged water from the separators
is intended to be fed back into the public drainage system.
If the discharged water is to be returned into waters, this is
only possible in individual cases following clarification with
the local water authority.
In the treatment of dirty water contaminated with light fluids
(commercial waste water) or waste water from the applica-

tion areas of Appendix 49 of the waste water regulations,
the observation of a limit value for hydrocarbons of 20 mg/l
cannot be considered to have been observed.
2.1.2 Coalescence separator to Separator system A
Separators for light fluids with coalescence device can be
used:
a) for the treatment of rainwater contaminated with light
fluids from surfaced areas, e.g. filling stations, oil storage
and handling areas, parking areas and streets in water
protection areas,
b) as a retaining system for light fluids for the safety of sys-
tems and areas where light fluids are handled, e.g. filling
stations, oil storage and handling areas,
c) for the treatment of dirty water contaminated with light
fluids (commercial waste water) produced taking into ac-
count the operating conditions of industrial processes, the
cleaning of parts contaminated with oil and the cleaning
of floor areas contaminated with oil (except workshop
floors),
d) for the treatment of waste water produced taking into
account the operating conditions of automatic vehicle
cleaning (partial flow: outlet from the closed circuit into
the drainage system), manual cleaning (vehicle washing,
engine washing, underbody washing, chassis cleaning in
washing bays, self-service or commercial washing bays -
except for the cleaning of workshop floors contaminated
with oil and for the drainage of areas used for the receipt,
storage, drying, dismantling and crushing of old vehicles,
e) for preliminary separation of light fluids from waste water
before further treatment in subsequent internal waste
water treatment plants.
