Appliances: what is a grease trap?

Self-tutoring about appliances: the tutor checks out the idea of a grease trap.

I recall decades ago talking to a restaurant owner who was sizing up a new project. He mentioned it needed a grease trap. Ever since then I’ve wondered what that meant – until now.

I’ve seen grease traps before without recognizing them. Logically enough, you might find one in a restaurant dish pit – it may be a stainless steel box that rests on the floor.

A grease trap separates grease and oil, along with particulate, from waste water:

1. Within the fixture, it slows the flow of the water so the grease and oils can float up, forming a separate layer on top. This layer is skimmed off.
2. At the same time, heavier particulate falls to the bottom of the tank. It, too, needs periodic removal.
3. With the grease and oil removed as a top layer, and the particulate removed as precipitate, only water carrying soluble materials should pass through the grease trap.

A grease trap is an elegantly conceived apparatus. Of course, they must be cleaned out regularly.
