Grease trap

The goal of the grease trap is to trap oil and grease so that it can be easily collected and removed from water. Grease traps are chambers made out of brickwork, concrete or plastic, with an odour-tight cover. Baffles or tees at the inlet and outlet prevent turbulence at the water surface and separate floating components from the effluent. A grease trap can either be located directly under the sink, or, for larger amounts of oil and grease, a bigger grease interceptor can be installed outdoors. Generally grease traps are fitted at garages, restaurants and other commercial premises where large quantities of oil or grease are discharged into wastewater.
