Oil separators
◢◢Requirements
An oil separator is designed to catch the source of pollutants
carried by run-off waters.
We offer a wide range of oil separators conform to standards
EN 858-1.
◢◢Fields of application
According to current rules, the oil separators have to be used
for the pre-treatment of surface waters carrying hydrocarbons,
for example:
▢▢ To treat waters stemming from industrial
processes, from the washing of vehicles, from
the cleaning of oil coated elements.
▢▢ To treat rainy waters (drainage waters)
contaminated by the oil resulting from waterproof
zones (car parks, roads, factories, …).
▢▢ To hold wide-spread light liquids and to protect
the surrounding zone (gas stations)
◢◢Advices
1. The rule becomes more and more strict as regards the
quantity of hydrocarbons rejected in natural environment.
It is the reason why we advise to rather use devices
provided with a coalescing filter which assures a
hydrocarbon discharge lower than 5 mg/l.
2. The good working of the separator imposes a sludge
trap large enough for allowing the settling of muds (see
following page).
3. The installation of the separator will largely be facilitated
if the level of water has been correctly measured.
We propose, for that purpose, fixed or adjustable extension
shafts which allow to position the device without
problem.

How to choose your device
CLASSES

CONFORMITY
The choice of an oil separator is often related to specific constraints of the considered case. We
give hereafter a summary of the criteria which can help to dimension the separator. As you can
easily understand, these tables do not consider the particular cases which can arise: please take
contact with our offices in case of doubt.
◢◢Parameters
▢▢ peak flow
▢▢ polluted load to treat
▢▢ density of the hydrocarbons
▢▢ compulsory output level
▢▢ surface to be treated (covered and/or uncovered)
▢▢ implantation site (load class of the lids).

◢◢Covered surfaces
In case of covered surfaces, rejected waters primarily come
from cleaning. The flow rate of the device will thus be calculated
according to the number of taps, heads, and all the
hydrocarbon rejects. For covered carparks, the table opposite
gives the size of the device according to the surface.

For larger surfaces, please contact us.
Flow
l/sec
◢◢Uncovered surfaces
The flow is directly related to the pluviometry, to the surface
of the catchment area and to the slope of the network.
▢▢ Separator without by-pass
For areas smaller than 1.400 m2, you’ll find in the table opposite
the flow rate and the type of separator taking into account
a pluviometry of 150 l/ha/sec. In this case the device treats
the totality of the incoming flow.
▢▢ Separator with by-pass
In this case the device treats ± 1/3 of the total incoming flow,
it allows to absorb an important flow in the event of storm, it
is especially adapted to treat water from uncovered carparks.
We strongly disadvise the use of an oil separator with by-pass
in an area where hydrocarbon is stored.

For the “Large Flows” separators (larger than 20 l/s) it is
advised to take into account the return 10 years formula.

◢◢1/ Separator WITHOUT by-pass
▢▢ The first part of the separator (sludge trap)
retains the mud and other particles. Muds
accumulate at the bottom of the sludge trap.
▢▢ Hydrocarbon charged water is directed towards the
second part of the separator and forwards from
bottom to top towards the coalescing cell. The
very small hydrocarbon particles are stuck on the
walls of the cell before going up on the surface.
▢▢ The layer of hydrocarbons grows thicker in time,
which causes “to push” the float towards the
bottom until closing the exit of the separator,
then the retention capacity is reached.
◢◢2/ Separator WITH by-pass
▢▢ Especially for places where there is no storage
of hydrocarbons (for example carparks), the
separators fitted WITH the by-pass device
enables not to treat the entire flow.
▢▢ When the entering flow is higher than the processing
capacity of the separator, the effluent goes through the
by-pass device and directly runs out of the apparatus.

◢◢3/ The automatic obturation
▢▢ In the event of problems, the automatic obturation
is a safety device preventing from the evacuation of
hydrocarbons towards the draining network (for example:
in case of lack of maintenance or accidental discharge).
▢▢ The obturation of the separator is carried out by a disc
assembled on a float tared to the density of hydrocarbons.
The float follows the layer of hydrocarbons until
obturation when the storage capacity is reached. Each
compartment is accessible by an inspection chamber.

▢▢ Empty sludge and hydrocarbons.
▢▢ The frequency of emptying depends on the
quantity of polluted matters in the separators.
▢▢ The sludge trap will be emptied once a year.
▢▢ The separator compartment will be checked
once a year. If the layer of hydrocarbons is
thicker tan 10 cm, it has then to be removed.
▢▢ In case of accidental heavier flow of
hydrocarbons, the separator has to be totally
emptied and the filled up with clear water.
