Grease Interceptor prevents the discharge of FOG (fats, oils and grease) from clogging public sewege lines and effluenting into our water resources. The US Environment Protection Agency and local sanitary departments establish and regulate a set of rules for restaurant owners to follow.

How does Grease Interceptor work?

Grease interceptor is often referred to as grease trap. Some might mistaken a grease trap as a smaller version of a grease interceptor, but literally, they are the same things. There are different sizes of grease traps suitable for different operations. We will discuss about how to estimate the size later in this article. Here is how it works. There are two chambers in a grease trap. In one chamber, grease is cooled to room temperature and solidifies. The grease then floats to the top of the chamber leaving water and other liquid submerges to the bottom. A crossover diagonal tube connects the two chambers and delivers water and liquid from the bottom of the first chamber to the second chamber, leaving FOG floating on top of the first chamber. As normal liquid level is reached in the second chamber, the liquid will flow downward to the sanitary sewer system. A functioning grease trap should be filled to the normal liquid level with water, grease, and food solids.

Where should we install the Grease Interceptor?

Grease interceptors are usually installed near the dishwashers, three compartment sinks, chinese stoves and other devices where grease, food deposits and oil are washed down drain. One large grease interceptor may be able to service all devices depending upon the conditions of the plumbing system and local jurisdictions. There could be one large grease interceptor or a few smaller ones, and they could be installed outside or inside, above-ground or under-ground, depending upon the engineer’s design and local code compliance. Installing the grease interceptor is not as straightforward as installing other storage tanks. An evaluation of the flow rates and contaminant levels must be calculated to determine which system is appropriate for each specific application. Prior to installation of this system, engineering specifications and drawings are created, and approval from the city or town must be attained.
