General; Application; Separator Description - Kessel NS 3 Installation And Operating Instructions Manual

2. General

2.1 Area of application
The separators are intended for use under specified conditi-
ons, see the Chapter "Installation and assembly", for instal-
lation underground or below the foundation slab in well-ven-
tilated areas.
2.1.1 Oil-fuel separators to Separator Class II
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 applicati-
on areas of Appendix 49 of the waste water regulations, the
observation of a limit value for hydrocarbons of 20 mg/l can-
not be considered to have been observed.
2. General
2.1.2 Coalescence separator to Separator Class I
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 sy-
stems 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 clea-
ning of floor areas contaminated with oil (except workshop
floors),
d) for the treatment of waste water produced taking into ac-
count the operating conditions of automatic vehicle clea-
ning (partial flow: outlet from the closed circuit into the
drainage system), manual cleaning (vehicle washing, en-
gine 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.
