• Hydrocarbon separator with
stopper, decanter and coalescing
cell Class I (< 5mg/l)
• Manhole container for fuel tank
USE
• It is an equipment made for retaining the hydrocarbon in
suspension that could be in dirt waters. It is obligatory headed
by a decanter that will retain the heavy material.
• The Spanish Water Law of 1985 and the corresponding local
regulations forbid the spill of lubricant, oil and hydrocarbon, new
or waste, in the superficial, underground waters or in sewers. So,
it is essential to put a decanter and hydrocarbon separator in the
service stations, mechanical workshops, parkings, vehicle cleaning
areas, etc.
• The hydrocarbon separators with coalescing cell are particularly
advisable to treat waters before their spill in sensible zones (rivers,
lakes, seas, etc.) or when the local regulation ask for some results
higher than it is usual.
These separators comply with the European Regulation
prEN858, separators of Class I (spill < 5mg/l).
• We have a high range of hydrocarbon separators that are made
of either polyethylene or polyester or steel treated against corrosion
(up to 150l/s).
• This technical card is referred to polyethylene separators with
decanter built-in, coalescing cell and outlet stopper, with nominal
size of 3 l/s to 15 l/s with a separated output lower than 5mg/l of
outlet hydrocarbons.
SEPARATOR TYPES
• The described separators have one peripheral decanter, one
coalescing cell, one separation zone and one automatic stopping
system. The decanters are calculated according to the future
European regulation that enforces a decanter volume mostly
equivalent to a 200 times the nominal flow of the kit.
FEATURES
• Retention capacity: 10 litres per l/s of nominal flow
• Treatment capacity: 3 to 15 l/s
• Decanter volume: 200 litres per l/s of nominal flow
• Output: 99,88% (lower than 5mg/l) for a density of 0,85

OPERATION
• The hydrocarbon separator with coalescing cell operation is based
on the gravitational separation of the heavy material that are non
water-soluble because of difference on densities.
• The waters with sludge and hydrocarbon go in the decantation
part, where the heavier particles are decanted and retained. In
the part of the kit separation of hydrocarbon, which density is
lower than the water, they float to the surface. The coalescing cell
is composed of alveolar plastic material; it accelerates the
gravitational separation process of the hydrocarbons that go away
from the separator. The water without hydrocarbons goes back
the wall and goes away from the kit. The kit has an automatic
stopping device, composed of a valve and a float that covers the
outlet of the separator before the maximum hydrocarbon retention
capacity is reached, preventing the hydrocarbon outlet.
INSTALLATION
• The kit must be installed in the exterior perfectly leveled and
nearest of the spill point of the influent to deal with. It will be totally
buried. The cover should get the ground level. The excavation
bottom should be perfectly plan and recovered with 10cm of sand.
The filling will be made with sand and no with stones or pea gravel.
The separator will be full of water at the same time that the
excavation refilling is made.
• The separator should be correctly ventilated to allow the gas outlet.
It is advisable a minimum diameter of 100mm for the ventilation,
which will be protected with a device that avoids the insect and
little animal entering.
• No pumping installation should head to the separator to avoid the
effluent emulsion.
• Regarding to the stopper, it is necessary to unstick the base float,
after filling the kit with water.
• In the event of an installation in a ground water surface or floodable
surface, please consult with our technical department.
MAINTENANCE
• The kit is made of plastic, so it is not sensible to the corrosion and
it does not need any maintenance.
• Please, periodically check that the ventilation is not blocked.
• When the retention capacity is reached, make an empty (pumping)
of the hydrocarbon, as the decanted sludges. Yearly, you have
to make a whole empty of the kit. Right away, after the empty,
refill again the kit with water and check that the automatic stopper
is duly floating in the upper water level.
• In some use cases, it will be necessary to increase the empty
numbers.
• If there is some ground water surface, the empty has to be made
when the weather is better (it is not raining).
• If the vehicles are passing near or over it and if the cover is not
at the level of the ground, a reinforced concrete slab should be
put that rests in the firm excavation sides, never in the same kit.
The slab should allow the access to the kit for its maintenance,
with the corresponding risers. This slab should be calculated to
resist the eventual charges.
