Grease Interceptor
•ParkUSA® GreaseTrooper® is a gravity interceptor designed to reduce the amount of FOG (fats, oils, and greases) in wastewater. Grease interceptors are used in establishments to remove excessive amounts of grease that may interfere with the proper drainage and treatment of wastewater. Even if accumulated FOG do not escalate into blockages and sanitary sewer overflows (SSO), they will disrupt wastewater treatment operations and increase costs. Most local plumbing codes prohibit any industrial user from discharging FOG over 100 mg/l into the public sewer system. Typical applications include commercial wastewater, institutional kitchens, and food processing plants. The waste discharge from these facilities usually contains high‐temperature water, high organic loads, FOG, suspended food particles, and detergents.

Grease interceptors work on the buoyancy principle. Animal fats and vegetable oils (grease) are 10 to 15 percent less dense than water and do not mix with water. Thus, fats and oils float on top of water. When waste-water enters a grease interceptor, the velocity is reduced enough that wastewater is given time to cool and separate into 3 layers. The grease rises to the top inside the interceptor and is trapped using a system of baffles. Solids settle at the bottom, and the separated clear water escapes under an outlet baffle. Grease interceptors can also have strainers for collecting solid debris, which reduce the amount of solids that settle at the bottom of the interceptor. Over time, solid and grease build‐up will accumulate in the grease interceptor. A routine cleaning schedule will ensure maximum performance of each interceptor.
