Why Grease Traps Are Your First Line of Defense

A grease trap, also known as a grease recovery device, is a plumbing fixture designed to intercept most solids and greases before they enter a wastewater disposal system. These devices are typically small and installed close to the source of the grease, such as kitchen sinks and dishwashers. Their main job is to prevent blockages in the sewer system that can lead to backups and expensive repairs.

How Grease Traps Keep Pipes Clean

Grease traps work on a simple principle. Fats, oils, and grease are most often lighter than water and tend to float on top. When wastewater enters the trap, it's slowed down, allowing time for the grease to separate and rise to the surface while solids settle at the bottom. The cleaner water then exits the trap and flows into the sewage system. Regular maintenance is required to remove the accumulated FOG and solids, ensuring the trap continues to operate effectively.

What Is a Grease Interceptor?

Grease interceptors are similar to grease traps in purpose but differ significantly in size, design, and placement. Engineered for high-volume establishments, these systems are installed underground, outside the kitchen area. They handle a larger amount of wastewater and are capable of processing it more efficiently, making them ideal for businesses with larger grease output.

Spotting the Differences Between Traps and Interceptors

While both devices aim to prevent FOG from entering the sewer system, their operational scale and installation requirements set them apart. Grease traps are smaller, require more frequent cleaning, and are suitable for lower-volume kitchens. On the other hand, grease interceptors are designed for larger volumes of wastewater, require less frequent maintenance, and are typically installed outdoors due to their size.

Making the Right Choice

Determining whether your business needs a grease trap or a grease interceptor depends on many factors, including the size of your operation, the amount of FOG your kitchen produces, and local regulations. Smaller establishments, like cafes and small restaurants, might find grease traps sufficient and cost-effective. Larger facilities, such as hotels and large restaurants, will likely require the more extensive capabilities of a grease interceptor. The goal is to find a solution that complies with local regulations and also supports your business's operational efficiency and sustainability goals.
