A better grease interceptor: More grease in less space

TZ-1826 Grease InterceptorTo understand the new TZ-1826 Trapzilla Grease Interceptor, consider two numbers: 1,826 and 11,000. 

The first is how many pounds of grease the TZ-1826 can hold. The second is how much a 1,000-gallon concrete trap weighs — a concrete trap that would hold a similar amount of grease, but would require heavy machinery to install and take up three times as much space as the TZ-1826.

How is that possible? That’s what happens when you apply a quarter century of grease interceptor innovation and oil-water separation expertise to a problem that a growing number of commercial food service establishments face: Lots of grease, but not much space for a high-capacity grease trap.

Why concrete interceptors ought to be left in the history books

Concrete grease trapIn 1884, Nathaniel Whiting patented the first grease interceptor design. These oversized, concrete boxes are still the default choice for many in the food-service industry.

Though innovative at the time, the design of these concrete interceptors has changed very little over the past 130 years and is fraught with problems in today’s world. 

Traditional concrete interceptors range in size from 300 or so gallons to several thousand. Though there are a few different designs, they all rely on the same principle — gravity.

Wastewater from a commercial kitchen flows down through the tank, where food particles sink to the bottom and oil rises to the top. The grease-free water in the middle then exits the tank and enters the public sewage lines.

Though these grease interceptors do the job, they don't necessarily do it well, do it efficiently or do it economically.
