Grease interceptor
Grease traps (also known as grease interceptors, and grease recovery devices) are plumbing devices designed to intercept greases and solids before they enter the sanitary system. There are three primary types of devices. The most common are the types specified by ASME. Utilizing baffles inside small 50 US Gallon tanks, they restrict flow and remove 85-90% of the incoming fat, oil, and grease (FOG). The second most common type of interceptor is the large in ground tank usually 1000 gallons. These units are constructed of concrete, fiberglass, or steel. They have much larger grease and solid storage capacities for high flow applications such as a restaurant or grocery store. These units can be designed to remove up to 99% of the incoming FOG. Some systems known as AGRUs (Automatic Grease removal Units) use mechanical skimmers to remove the surface grease when trapped.
