Why is a hydrocarbon separator mandatory in washing areas?

Hydrocarbon separator: OCEANIA ENVIRONMENT solutions:

Hydrocarbon separators are mandatory in washing areas.

Treatment of hydrocarbon pollution: what is a separator used for? An oil separator works according to the principle of gravity by density difference: heavy substances sink to the bottom and light substances such as hydrocarbons and oils float on the surface. A hydrocarbon separator is intended to trap hydrocarbons in suspension in rainwater and effluents collected during the washing of machinery.

The coalescing filter is made up of a mass of floating media with a specific surface area of ​​200 m²/m³. These floating supports are made of synthetic material, made of polypropylene and occupy a large part of the volume of the separator, including the sludge trap. The coalescer filter increases the exchange surface and promotes the coalescence of hydrocarbons.

Called coalescence, the action by which the fine hydrocarbon droplets created by the turbulence of the effluent agglutinate to form larger droplets, thus benefiting from a higher upward speed. This phenomenon allows a better and faster separation of the hydrocarbons during the passage time.

The effluent thus obtained complies with European standards. The floating-type coalescing filter clogs little and is much easier to clean than a conventional coalescing cell.

for maintenance, it is strongly recommended to associate an alarm which will indicate that a maintenance operation is to be carried out.
