SEPARATOR
OF HYDROCARBONS

WHAT IS IT USED FOR ?

The operation of the hydrocarbon separator is based on the gravity separation of materials not soluble in water. Hydrocarbon-laden water enters the device, hydrocarbons, with a density lower than that of water, rise to the surface. A float system located in the lower part closes the device when the hydrocarbon retention level is reached.
A hydrocarbon separator will always be preceded by a sludge trap with storm overflow (bypass) or not, with a volume equivalent or greater than the volume of the separator in order to be able to filter and store the heavier elements that could obstruct the tank. separator (sand, mud, gravel, bolt… etc).

THE DIFFERENT CLASSES

Class 1 separators are separators equipped with coalescing filters which allow a discharge at the treatment outlet less than or equal to 5 mg per liter
of hydrocarbons, the treated water can therefore be discharged directly into the natural environment or the rainwater network.
Class 2 separators do not have a coalescing filter and provide a discharge greater than or equal to 100 mg / L. The pre-treated water will therefore be sent to a treatment plant.
