Let’s find out how this grease trap works to avoid such issues.

How Does a Grease Trap Work?

A grease trap functions by cooling the warm or hot greasy water and allowing the fat, oil, and grease to cool. It can separate the different layers of this waste with water.

FOG, fat oil, and grease are lighter in density and easily float at the surface of the tanks. The cooler water without the fats flows into the central sewer system. 

When wastewater from the kitchen moves into the grease trap, the grease and the oil rise to the surface and are trapped inside it using a system of baffles, this grease and oil fill the tap from top to bottom and allow the clean water at the bottom of the trap to flow into the main sewer line.

This is why you see a layer of grease at the top of the grease trap, and when this layer accumulates the oil, fats, and grease, the trap needs to be cleaned out. 

Moreover, the size of a grease trap makes also makes a huge difference. For instance, cleaning a grease trap takes work, and if you have a large trap, it means you need less frequent cleaning.  

These traps used in the interceptor utilize internal baffles and provide maximum space and time for the separation by lengthening the circulation path and the flowing rate. To maximize the separation of FOG, the wastewater makes its way inside the grease trap and, in this step, allows the mixing of air.

Primarily, restaurants use these large traps, which means food waste settles at the bottom of the tank and reduces the amount of volume in the grease trap—similarly, rotting food within the grease trap results in toxic waste that generates rot out of the tank.

The effectiveness of the grease trap depends on several factors, including the design, location, and size of the kitchen and drainage system. Because every kitchen’s size and location are unique, we have to adapt the things according to this.

The average grease trap will retain from 50% to 90% of the FOG that enters it. But, to increase the effectiveness of grease control, you can use more units where each unit separates between 50% and 90% of the FOGs that enter it.
