Oil & Grease Separators
These chambers rely on the different density of oil and grease compared to water. As the water enters the chamber the less dense and oil begin to separate and rise to the surface.
The water, now free of impurities passes under the panel in the centre of the chamber and continues to the outlet. The oil and grease rests at the waters surface where it cannot exit the chamber until it is ready to be removed.
Another method is to have a second outlet at the top of the chamber that allows the grease or oil to flow onward where it can be stored and disposed of at a later date, this prevents a large build up of material in the chamber itself.
Oil & grease traps are commonly seen in many locations, from kitchens to petrochemical plants.
These chambers are also available fitted with slip traps for the removal of large debris.
