Introduction
As a restaurant owner, you know the importance of maintaining a clean and safe kitchen. One way to do this is by installing a grease interceptor or a grease trap. But what are these devices and how do they differ from each other? In this article, we will discuss the key differences between a grease interceptor and a grease trap.
What is a Grease Interceptor?
A grease interceptor, also known as a grease separator, is a large device that is installed outside the building. It is designed to trap and separate fats, oils, and grease (FOG) from the wastewater before it enters the sewer system. Grease interceptors are required by law in many areas and are typically used in commercial kitchens that produce a high volume of FOG.
How Does a Grease Interceptor Work?
Wastewater from the kitchen flows into the grease interceptor, where the FOG separates from the water due to its density. The FOG rises to the top of the interceptor and is trapped by a baffle, while the water flows out of the bottom of the device and into the sewer system.
What is a Grease Trap?
A grease trap, also known as a grease interceptor, is a smaller device that is installed under the sink or in the floor. It is designed to trap FOG before it enters the wastewater system. Grease traps are typically used in smaller commercial kitchens or residential kitchens.
How Does a Grease Trap Work?
Wastewater from the kitchen flows into the grease trap, where the FOG separates from the water due to its density. The FOG rises to the top of the trap and is trapped by a baffle, while the water flows out of the bottom of the trap and into the sewer system.
Key Differences Between Grease Interceptors and Grease Traps
Size and Capacity
The biggest difference between grease interceptors and grease traps is their size and capacity. Grease interceptors are much larger and are designed to handle a higher volume of FOG than grease traps. Grease interceptors are typically installed outside the building, while grease traps are installed under the sink or in the floor.
Maintenance
Grease interceptors require more maintenance than grease traps. They need to be cleaned at least once every 90 days, and the FOG that is trapped inside needs to be disposed of properly. Grease traps, on the other hand, only need to be cleaned once every 30 days.
Cost
Grease interceptors are more expensive than grease traps due to their size and complexity. They require professional installation and can cost several thousand dollars. Grease traps, on the other hand, are relatively inexpensive and can be installed by a plumber.
Conclusion
In summary, grease interceptors and grease traps are both important devices for maintaining a clean and safe kitchen. Grease interceptors are required by law in many areas and are designed to handle a high volume of FOG. Grease traps are smaller and less expensive, making them a good choice for smaller commercial kitchens or residential kitchens. When choosing between a grease interceptor and a grease trap, consider the size of your kitchen, your budget, and the maintenance requirements of each device.
