The Greasezilla® grease-separating process enables the operator to remove FOG from the grease trap waste stream, reduce waste disposal expenses, create a new revenue stream and run a greener, more eco-friendly operation. It produces and consumes its own fuel: brown grease, a byproduct of the separation process.

Here’s how the system works: First let gravity separate the water and the grease in decant tanks. Drain the water into a municipal sewer drain. Pump the remaining grease and sludge into a 10,000-gallon Greasezilla® tank. Grease traps typically have a water-to-sludge ratio of 3:1 or 4:1 and brown-grease content of 3 to 10 percent.

A hydronic heater heats the tank contents to a temperature of about 160 degrees. In approximately 24 hours, the contents separate into four distinct layers: rich brown grease (a valuable commodity sold directly as a biofuel or as feedstock for biodiesel); debris; water; and food particles. The brown grease can be pumped out and sold while the remaining content, which is pasteurized and nearly oil free, may be land-applied or discharged into a sewage treatment facility. The Greasezilla® unit runs on brown grease; about 5 percent of the brown grease produced in each batch is pumped back into the system and used as fuel.

A standard Greasezilla® system includes dual 10,000-gallon, double-wall, insulated steel tanks. Two tanks increase efficiency. As one tank processes the other can be harvested, drained and reloaded. A full tank weighs about 95,000 pounds, so any commercial building with a concrete slab can handle the weight. The unit requires no special electrical upgrades.

Greasezilla® eases the financial sting of ever-increasing disposal fees, labor costs and transportation expenses associated with trips to further treatment and waste water plants. In addition, it generates another revenue stream by selling brown grease and/or processing grease for other pumpers.
