Grease Trap

Marine Grease Trap

As per Marpol 73/78 Annex IV and V 5.4.4 Galley wastes

All galley wastes that may contain grease should flow through grease traps to a retaining box prior to discharge overboard with a distance of 3 N.M. from the closets line of land (territorial sea – 12 N.M.) or to a treatment aboard ship.

The grease collected may be disposed of by incineration, by storage for shore disposal, or in any manner stated by the law.

Food waste needs to be handled as well as per Annex V


DeFraWater® is a partner with Grease Guardian® for the distribution of their grease separation equipment for galleys and plant rooms on board any vessels.

The proposed Marine Range has different design configurations to suit confined spaces, and together with unique features including automated waste oil recovery, will operate efficiently in marine environments.

Proven results give us confidence to promote the Grease Guardian Marine Range from super yachts to cruise liners and everything in between.

Suitable grease removal system will be required to pre-treat the kitchen waste water accordingly, prior to discharge at sea or to go for treatment on board.

In order to keep the best working condition of the on board waste water treatment plant that receives kitchen waste water, it is good practice to reduce the loading of the kitchen waste water. This is done by reducing/removing solids and fat oil and grease before the water will enter the plant.
