A grease trap is able to separate the different layers of waste with water because the FOG material rises to the top and water remains at the bottom with the solid food debris. This happens because the FOG is lighter and less dense than the cooled water.

As more wastewater enters the tank, the grease-free water is pushed out of the tank. The rotting brown grease inside a grease trap or grease interceptor must be pumped out on a scheduled basis. The brown grease is not recycled and goes to landfills.

Full Trap This will soon lead to clogs in the lines leading into and out of the grease trap. A full trap will also restrict the flow of water through the system. As a result, you may find that water has begun backing up in your sinks and dishwashing pits.

Whether automatic or manual, grease traps work by trapping the FOG that rise to the top from wastewater before it enters the drains. When wastewater enters a grease trap, it slows the water flow down significantly, separating it into solids on the bottom layer, wastewater in the middle, and FOG on the top.

The total depth of the floating fats, oils and grease (FOG) layer, plus the settled sludge layer cannot exceed 25% or more of the total liquid depth of the inceptor.
