Where should Grease Traps be Used?

The use of Grease Traps or Grease Separators is largely dictated by local or municipal codes however regardless of the code using them it is good for your sewer system. Before we explain how grease traps work it?s probably a good time to explain what they actually do. A grease trap is appurtenance designed to capture grease, fats and oils before they enter the sanitary system.

A grease trap should always be used to prevent grease from getting into the sewer lines in any school, restaurant, hotel, hospital or pretty much any building that has the facilities to prepare food en mass. Grease interceptors should also be used in dairies, food processing plants, meat packing facilities where fats and greases are a by-product of the processes.

As the water drains into the interceptor it passes a flow restrictor . (Most grease traps are equipped with a flow control device but some are not. The plumbing contractor would then be responsible for the flow control device). The flow control device slows things down so the interceptor can do it?s thing. The water then passes through a series of removable baffles that aids in separating greases, fats and oils. Once the grease is separated it floats to the top where it accumulates. When the grease trap no longer functions efficiently the top should be removed and the grease should be cleaned out and disposed of safely. Believe it or not grease traps can remove between 80% and 90% of contaminating greases.

Grease adheres to the inside of sewer lines slowly choking off flow. Grease traps catch the grease before it has a chance to make a mess of things like sewer back ups and costly repairs.

If grease isn?t treated it can make it?s way to our rivers and lakes. We don?t have to explain how that would effect the ecosystem.

The grease interceptor isn?t the only trap that you can use to protect your drainage system. Grease traps are not design to capture solid materials. In a restaurant or cafeteria application in addition to grease waste you also get solids from food scraps. Grease attracts solids so you end up with grease cakes (yummy!!) that promote decay leading to pretty foul odors. As you can imagine under these conditions pipes can become blocked and the grease trap itself can become filled with debris.
