When industrial equipment with an oil sump is placed outside and exposed to the weather, rainwater can fill this secondary containment. To avoid the risk of overflow in the event of rain and simultaneous oil leakage, the retention tank must be equipped with a system capable of filtering and continuously discharging rainwater while retaining the hydrocarbons inside the secondary containment. The discharged water must not be contaminated with more than 5 ppm of hydrocarbons according to EN 858-1 ("light liquid separation systems").
To achieve this, we offer prefabricated hydrocarbon separators specially designed for hydrocarbons and esters and hydrocarbon water filters that operate either by gravity, i.e. without electricity and self-locking, or pumped systems equipped with level detectors and alarms.
