Understanding How Grease Traps and Interceptors Work

Grease traps and interceptors play a vital role in preventing grease and oil from entering the wastewater system and causing blockages and environmental damage. Whether in a restaurant, commercial kitchen, or food processing facility, these devices are designed to capture and separate grease, ensuring the smooth operation of plumbing systems and compliance with regulations. In this blog post, we will explore how grease traps and interceptors work, shedding light on their importance and functionality.


Grease Traps:

  • Grease traps are typically installed inside the kitchen area, near sinks and dishwashers.

  • They work by utilizing the principle of gravity and buoyancy to separate grease from wastewater.

  • As wastewater enters the trap, it slows down, allowing fats, oils, and grease (FOG) to rise to the surface.

  • The separated grease is trapped within the device, while the clarified water continues to flow into the sewer system.

Grease Interceptors:

  • Grease interceptors are larger versions of grease traps and are commonly found outside the building, underground.

  • They are designed to handle higher volumes of wastewater and grease accumulation.

  • Similar to grease traps, interceptors rely on gravity and buoyancy to separate FOG from wastewater.

  • As wastewater enters the interceptor, it undergoes a series of baffles, slowing down the flow and facilitating the separation process.

  • The FOG floats to the top, solid particles settle at the bottom, and clarified water is discharged into the sewer system.

Maintenance and Cleaning:

  • Both grease traps and interceptors require regular maintenance and cleaning to ensure their optimal performance.

  • Routine inspections and scheduled pumping are necessary to remove accumulated grease and prevent blockages.

  • Professional plumbing services should be employed to clean and maintain these devices, ensuring compliance with local regulations.

Conclusion:

Grease traps and interceptors are critical components of plumbing systems, specifically in commercial kitchens and food establishments. By effectively capturing and separating grease from wastewater, these devices help prevent clogs, protect the environment, and maintain proper plumbing functionality. Regular maintenance and adherence to local regulations are essential for the efficient operation of grease traps and interceptors.
