How does a grease trap work?

 

The first thing that you will notice when you install your grease trap is that it is not added directly to the drain of the sink or appliance that it is filtering. There is a flow control valve that keeps the water from reaching the grease trap too quickly before the trap itself. Another thing that may catch your eye is that there is no actual screen used to filter the FOG and debris out of the water.

 The distance between the drains and the grease trap is specifically used to cool the water on its way to the trap. As the water cools, there are two principles at work; the first is that food debris sinks, and the second is that FOG floats. The flow control will keep the water from washing the debris from the trap during times of faster flow.

 The grease trap is a well that keeps the floating oils at the top of the water from passing through by making the water fill the well. There is a wall that travels part of the way down the well on the input side so that the water needs to pass under it to exit through the drain. The FOG is blocked from traveling to the drain by the wall (because it floats), and the larger food debris sinks to the bottom of the trap and cannot travel up to the drain on the other side of the wall.
