FUEL/OIL SEPARATORS
Fuel/Oil Separators or interceptors (the terms can be used interchangeably) are used to protect water bodies and sewer systems from light fluids¹. MACTRAP Fuel/Oil separation systems intercept mineral oils and fuels collected in wastewater from sources such as petrol stations, car washes, vehicle repair garages and industry. These oil and fuel separators are amongst the safest and most effective light fluid capture systems available.
Fuel/Oil Separators can be used:
- For the treatment of rainwater contaminated with light fluids from surfaced areas.
- As a retaining system for light fluids where light fluids are handled.
- For the treatment of dirty water contaminated with light fluids.
- For the treatment of waste water produced by vehicle wash bays.

Fuel/Oil SEPARATORS
Wastewater enters the separator and the heavier sludge and sediment sink to the bottom of the chamber while at the same time the light fluids rise to the surface. Cleaned wastewater exits the separator without allowing any of the separated sludge or light fluids to leave the separating chamber.
Coalescence Separators
Coalescence Separators operate on the same principle as Fuel/Oil Separators. A coalescence filter is integrated into the system to catch droplets of oil too small to separate from the wastewater. Fine droplets of oil are trapped by the filter where they combine with other fine droplets until they reach buoyancy, and rise to the surface.
Self activated closure lock
Both the fuel/oil and the coalescence separators are equipped with a self-activated closure lock which completely closes the outlet of the separator when the separator reaches its maximum fuel/oil storage volume. This prevents the escape of light fluids into the drainage system.
Alarm units
To reduce the chances of the separator shutting down due to overcapacity in the fuel/oil storage chamber, an alarm unit can be installed which monitors the fuel/oil level. MACTRAP recommends the installation of these alarm units in high fuel/oil applications.

Covers & Risers
Mactrap separators are available with Class D Vehicular lids in cast iron, and Class A Pedestrian lids in HDPE.
Flexible coupling allows easy installation into the surrounding medium.
The risers and covers are fully sealed.
The riser mounts are pre-welded and the riser flanges and screw on lids are provided separately. The riser flanges and screw on lids are installed once the exact height of the installation is known. The risers can be cut on site to the required height.
Surrounding concrete or other medium must be engineered for the appropriate loading.
