What is a Grease Removal Device, (GRD)? How does it work?
A GRD is a piece of equipment connected to the sewer line close to the source of FOG (fats, oils and grease) being discharged. It is made up of a baffle system inside intended to slow the discharge long enough for the FOG to separate from the gray water (retention time). The FOG floats to the top of the reservoir inside the device, gray water flows through the sewer system and food particles drop to the bottom of the reservoir.
