What is a grease trap?

Simply put, a grease trap is a receptacle that kitchen waste-water flows through before entering the sanitary sewer lines. This receptacle — technically defined as a grease interceptor — interceptors, captures, or “traps” grease. How?

Grease, the industry term for animal fats and vegetable oils, is 10 to 15 percent less dense than water. Grease also won’t mix with water. As a result, fats and oils float on top of water.

When kitchen waste-water flows through a grease interceptor, the grease and oils rise to the surface inside the trap and are trapped using a system of baffles. The captured grease and oils fill the trap from the top down, displacing “clean” water out of the bottom of the trap and into sewer line.

Peer into a grease trap and you’ll see a mat of grease. When this mat of grease gets deep enough, the trap must be cleaned out.

GREASE TRAP REQUIREMENTS ANY ESTABLISHMENT THAT HAS FOOD PREPARATION OF ANY TYPE IS REQUIRED TO HAVE AT LEAST ONE 1500 GALLON EXTERIOR GREASE INTERCEPTOR

These establishments include, but are not limited to: Restaurants, Ice Cream Shops, Coffee Shops, Cafeterias, Deli’s, Butcher Shops, Bakeries, Convenience Stores, Motels, Hotels, Churches, Schools, Day Cares, Etc.

The modern grease trap (interceptor) comes in three main types.

Normally these units are carbon steel or plastic. Hydro-mechanical grease traps control the flow of water allowing the hot water to cool. The baffle catches the FOG and keeps it inside the grease trap. These grease traps must be cleaned manually and often. The sizing of the Hydro-mechanical units are expressed in poundage and in gallons per minute (GPM) flow.

 ➡ The second type of grease trap is Gravity. This type of grease trap uses compartments of two or more and uses the larger amount of water flowing to slow down the water inside the trap. This allows for FOG to become buoyant and to separate. The physical size of Gravity grease traps compared to the Hydro-mechanical is large. These grease traps are more efficient, allowing 90% of the FOG to be collected out of the water. The sizing of the Gravity units are expressed in the gallons it will hold.

 

 

grease trap ➡ The third is an Automatic Grease Removal Unit (AGRU). This type of grease trap utilizes mechanical and electrical components to actually skim FOG out of the water. These systems are smaller yet highly efficient. Most AGRU units can eliminate 99% of FOG from water. Most have an internal collection device for food particles, a heating element and a external FOG collection unit. The AGRUs are more expensive than the the other two, but one can clearly see that they are lower maintenance and high efficiency. Sizing of these units varies greatly and can come in sizes small enough to place under a sink or large enough to accommodate an entire restaurant.
