Restaurant wastewater enters Grease traps from 3-compartment sinks and automatic dishwashers. The grease trap tank acts as a reservoir holding the wastewater and food solids that enter the trap. As the wastewater cools, the fat, oil, and grease (FOG) harden and the food solids settle. The FOG, being lighter than water, floats to the top of the grease trap. The wastewater is forced through the grease trap and out to the sanitary sewer. The FOG and food solids remain in the tank, increasing in volume daily. Food solids and grease sludge (brown grease) settle to the bottom of the grease trap.
