3. How Does Grease Trap Work? 

  • Grease traps work on the basis that FOG (fat, oils, grease) is 10 to 15 percent less dense than water and that grease won’t mix with water. Thus, fats and oils float on top of the water.
  • When wastewater enters a grease trap, the flow rate is reduced enough so the wastewater is given enough time to cool and separate into 3 layers.
  • The grease rises to the top inside the interceptor and is trapped using a system of baffles.
  • Solids settle at the bottom and the separated clear water escapes under an outlet baffle. 
  • Many grease traps also have strainers for collecting solid debris, which reduces the number of solids that settle at the bottom of the trap.
  • Over time, solids and grease build-up, and if left to accumulate for long enough they can start to escape through the outlet, and in some circumstances, they can back-up through the inlet.
  •  For this reason, the trap must be cleaned/pumped out regularly.

  • made of metal, fiberglass, or PVC.

2.) In-ground (or Below-ground) Grease Traps

  • buried underground and generally have larger capacities than above-ground types.
