More reliable grease traps lead to better compliance

Though traditional concrete grease traps, if regularly pumped out, fulfill their basic mission of intercepting fats, oil and grease, they are susceptible to failure. As a plumbing inspector or pretreatment coordinator, that should concern you.

Traditional concrete traps corrode and become less efficient over time. Because their efficiency is substantially impaired once they reach about 25 percent of their capacity, they must be emptied more frequently and built to larger specifications.

And when they fail, or if they aren't pumped out on schedule, grease can enter the sewer system.

Durable, highly efficient Trapzilla Supercapacity Grease Traps don't have these problems. As a result, commercial kitchens that use Trapzilla systems are less likely to accidentally be out of compliance or inadvertently release excess grease into sanitary sewer lines.

Durable

Traditionally, grease traps have been constructed of concrete and metal. But over the 5-8 year life of a traditional trap, the concrete and metal components corrode. This can lead to ruptures and failures even if the trap is regularly emptied.

Trapzilla units are constructed of highly durable, corrosion-resistant rotationally molded polyethylene. The circular design of the trap also eliminates hiding places for H2S producing bacteria. When H2S builds up, it increases the acidity of the wastewater/grease mixture, corroding concrete and metal components.

Efficient

Traditional grease concrete traps must be emptied once they reach about 25 percent of their volume. Beyond that, they are much less efficient and excess fats, oil and grease may find their way into the sewer system.

Trapzilla systems have a flat efficiency curve, which means they never lose efficiency even as they fill with accumulated grease. The largest Trapzilla unit, the TZ-600, is more than 90 percent efficient.

This allows a large volume of waste to be trapped and held in a compact unit, and ensures that the unit continues to effectively intercept grease from kitchen effluent even as it fills.

Resources

Trapzilla grease interceptor systems are in use in a wide variety of traditional and nontraditional food service settings, keeping fats, oils and grease out of wastewater treatment systems.
