How do grease arrestors work?
Grease traps work on the basis that animal fats and vegetable oils (grease) are 10 to 15 percent less dense than water and that grease won’t mix with water. When wastewater enters a grease trap, the flow rate is reduced enough so the wastewater is given enough time to cool and separate into 3 layers.

A grease trap is a long, rectangular box that is installed in the sewer line of a commercial kitchen. Most homes don’t actually need one because they don’t deal in the kind of volume that grease traps are built for. The most damaging of these substances is FOG (Fats, Oils, and Grease).
Is a grease interceptor the same as a grease trap?
Whether the unit is a grease trap or grease interceptor, the technology works the same. The difference between a grease trap and a grease interceptor is the flow rate of wastewater that the device can handle. A grease trap works well with a lower volume of flow; less than 50 gallons per minute.
