Why Food Waste Should Not Be Entering Your Grease Trap


If you own a restaurant and have installed a grease trap to take care of the fats and oils that pass down your drains, then you have taken the first step in investing in the health of your drainage system. This can help to greatly reduce clog issues, especially the ones that require professional assistance. While this is true, you still may be making one mistake that can lead to substantial issues. This involves forcing food waste down the drain. Keep reading to understand why this is a such an issue.

Food Can Clog The Trap

Grease traps are special devices that are specifically constructed to capture grease and oil wastes. The trap is essentially a large box with an inlet pipe that allows waste water to flow into it. The pipe exists in the bottom of the box and water flows into one containment area. A second holding tank sits on the other side of the box and allows water to flow out of the box through an outlet pipe. A small opening sits between the two containment tanks towards the bottom of the trap. 

The opening allows only water to flow through to the other side of the trap while grease floats to the surface. However, if there is solid matter in the wastewater that includes food materials, then the solids will sink in the inlet portion of the grease trap. The food can easily accumulate and clog the inlet pipe and the baffle opening that sits between the two holding areas. This can result in a clog.

In some situations, the food particles can absorb grease and move into the outlet part of the grease trap. The matter can then clog the outlet pipe. This rarely happens though, and you will typically end up with an annoying, but easily solvable clog issue. While this is true, you should keep your workers from washing food down the drains. This can be difficult when it comes to the dishwashing sink, so make sure to add a strainer to the drain. You can also add a separate trap to this sink to collect debris before it moves to the larger trap in your floor or outside your restaurant. The smaller traps are sometimes called grease interceptors. Just makes sure a vent is placed on the inlet pipe or odors will come up through the drain.

Food Causes Odors

Speaking of odors, when food is allowed to accumulate and sit in the grease trap, bacteria will decompose the bits of food. This causes sulfur gasses to be released back through the drain. While a U-shaped fitting on the bottom of the drain can keep some of these odors at bay, they may be strong enough to infest your kitchen.

Meat decomposition odors are by far the strongest and most foul, and there is often a great deal of meat attached to greasy plates. Make sure that large garbage bins set next to your sink so that all dishes can be scraped thoroughly before they are washed. 

Since it is not always possible to avoid food from getting into the trap and smelling up your kitchen, purchase and use an additive. While some people will buy additives that specifically attack the grease and break it down, it is cheaper and easier to have the trapped cleaned as grease builds up. Emptying on a schedule is wise. Most restaurants require a one to three month cleaning

To take care of food odors, add an enzymatic odor control fluid. The product will encourage the formation of bacterial colonies with microorganisms that do not produce sulfur. You can also add an oxygen product, because the addition of oxygen can cut down on odors as well. For more information, contact companies like AAA Pumping Service
