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 standardsEN 858-1.

Fields of application◢

According to current rules, the oil separators have to be used

for the pre-treatment of surface waters carrying hydrocar-bons, for example:

To treat waters stemming from industrial▢

processes, from the washing of vehicles, fromthe 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◢

The rule becomes more and more strict as regards the1.

quantity of hydrocarbons rejected in natural environ-ment. It is the reason why we advise to rather use de-vices provided with a coalescing filter which assures ahydrocarbon discharge lower than 5 mg/l.The good working of the separator imposes a sludge2.trap large enough for allowing the settling of muds (seefollowing page).The installation of the separator will largely be facili-3.tated if the level of water has been correctly measured.We propose, for that purpose, fixed or adjustable exten-sion shafts which allow to position the device withoutproblem.

Classes of separators

There are 2 classes of separators:◢

Class 1: with coalescing filter▢ Residual content lower than 5 mg/l according to essay standard EN 858.

Class 2: without coalescing filter▢

Residual content lower than 100 mg/l according to essay standard EN 858.

Choice of the treatment

1. Total treatment◢ (device without by-pass storm overflow)

Installation straight on the net

For large surfaces with risk of accidentalpollution.

Example : hydrocarbons storage areas,

fuel distribution centers.

Installation right after the storm basin

with flow regulator

with risk of accidental pollution.The basin requires a lot of space.

2. Partial treatment◢ (device with by-pass storm overflow)

Installation straight on the net,

with by-pass device in the separator

For large surfaces with risk of accidentallimited pollution.

Example: parking areas, roads.

Installation in by-pass on the net,with by-pass device upstream the separator

For very large surfaces and on an existing net.

How to choose your device

The choice of an oi l separ ator is often relate d to specif ic constrai nts of the consider ed case. We

give hereafter a summary of the cr i ter ia which can help to dimension the separator. As you can

easi ly understand, these tables do not consider the part icular cases which can ar ise: please take

contact with our off ices in case of doubt.

Covered surfaces◢

In case of covered surfaces, rejected waters primarily come

from cleaning. The flow rate of the device will thus be cal-culated according to the number of taps, heads, and all thehydrocarbon rejects. For covered carparks, the table opposite

gives the size of the device according to the surface.

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 oppo-

site the flow rate and the type of separator taking into accounta pluviometry of 150 l/ha/sec. In this case the device treatsthe 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-passin an area where hydrocarbon is stored.

Operation of the oil separator

1/ Separator WITHOUT by-pass◢

The first part of the separator (sludge trap)▢

retains the mud and other particles. Mudsaccumulate at the bottom of the sludge trap.

Hydrocarbon charged water is directed towards the▢

second part of the separator and forwards frombottom to top towards the coalescing cell. Thevery small hydrocarbon particles are stuck on thewalls of the cell before going up on the surface.

The layer of hydrocarbons grows thicker in time,▢

which causes “to push” the float towards thebottom 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), theseparators fitted WITH the by-pass deviceenables not to treat the entire flow.

When the entering flow is higher than the processing▢

capacity of the separator, the effluent goes through theby-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 ofhydrocarbons 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 untilobturation when the storage capacity is reached. Eachcompartment is accessible by an inspection chamber.

Maintenance instructions

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 isthicker tan 10 cm, it has then to be removed.

In case of accidental heavier flow of▢

hydrocarbons, the separator has to be totallyemptied and the filled up with clear water.

Mud/sand level alarm in the sludge trap: SANDSET-1000◢

The SANDSET-1000 is a complete system which makes it possible to detect a decanted sand or mud level at the bottom of a

tank. The ultrasound probe generates an alarm when the sand or mud level arises between the two sensitive elements of theprobe.

The probe does not require any calibration, nor particular maintenance. It only needs to be installed at the right level and to be

set under tension. It is in conformity with directive ATEX 94/9/EC for a use in a potentially explosive atmosphere.

The separator has to be buried.1.Place the separator horizontally at the bot-2.tom of the excavation (lean concrete).Connect in/outlet on the pipe.3.Connect ventilation.4.Place extension shaft (if necessary) and5.adjust it to the floor level.

Fill up the separator with clear water.6.At the same time backfill with sand.In case of placing underneath road traffic,7.separators have to be convered with castiron covers (class D-400 kN).The covers will be sealed in the self-holdingconcrete slab, which will be supported bythe edge of the excavation (thickness andreinforcement to be defined).

Caution: in case of ground water tableFirst of all, build the ballast concrete plate

on which the separator will be installed.Don’t forget the reinforcing rods to anchor theseparator.

The concrete mass has to be calculated to

compensate fot the vertical push of the waterwhen the separator is empty.

Finally the separator has to be strapedwith anchoring belts.
