Oil and grease traps, also known as grease interceptors or grease traps, are devices used in kitchens and food service establishments to capture and prevent fats, oils, and grease (FOG) from entering the wastewater system. They help in preventing blockages in plumbing and the accumulation of grease in sewer lines. These traps typically consist of a container located in the wastewater drainage line. As the wastewater flows through, the trap slows it down, allowing fats, oils, and grease to separate and float to the top while allowing water to continue its flow. Regular maintenance, such as cleaning and emptying the trap, is crucial to ensure its effectiveness.
