Grease Trap Vs Grease Interceptor: What’s the Difference?

grease trap, grease interceptor, grease trap vs grease interceptorIf your business includes a commercial kitchen, then it most certainly has a grease trap or a grease interceptor. Most people are only either familiar with the former, or they use the terms interchangeably. While the two may serve the same function, they’re not exactly identical.

What Is a Grease Trap?

Let’s start with the more common grease trap. As you may know, a grease trap collects fats, oils, and grease (FOG) from cooking deposits. This prevents the solids from entering the plumbing system.

You can usually locate the grease trap directly under the sink. The size ranges from a shoe-box to a small refrigerator. The contraption is designed for low-flow plumbing, meaning it can handle plumbing pressure up to 50 gallons per minute.

What Is a Grease Interceptor?

A grease interceptor is for larger scale applications and can handle a flow rate exceeding 50 gallons per minute. Due to the heftier bulk, technicians have to install interceptors outside of the building rather than under the sink. They’re usually installed underground with access via a manhole cover.

Grease interceptors are for larger establishments, such as hotel restaurants and diners that serve on a nearly non-stop basis.

Cleaning Interval

Grease traps require more frequent cleanings since they have a smaller storage capacity. We recommend a cleaning about once a month. Grease interceptors require a cleaning every three months.

Of course, frequency is dependent on kitchen activity. As a rule of thumb, you need to clean grease traps and interceptors once they fill to one-fourth capacity. Blockages usually arise once traps and interceptors exceed this level.
