What is a Grease Trap? An Effective Solution for Grease Treatment in Wastewater

In daily use, especially in household kitchens, restaurants, or industrial areas, wastewater containing grease is a significant issue. Inefficient treatment can lead to clogged pipes, environmental pollution, and an increased risk of drainage system failures.
In this article, we will explore what a grease trap is, how it works, and why it is an effective solution for grease treatment in wastewater.

What is a Grease Trap?

A grease trap (also known as a grease interceptor or grease separator) is a device designed to separate grease, oil, and solid particles from wastewater before it is discharged into the environment or sent to further treatment stages.

This device operates based on the principle of density difference: grease and oil are lighter than water, so they float to the surface and can be separated.

Types of Grease Traps

Choosing the Right Grease Trap

• For households: Choose a compact plastic or stainless steel grease trap.

• For restaurants: Prefer stainless steel or composite grease traps with medium capacity.

• For industrial use: Composite or concrete grease traps are optimal.

How Does a Grease Trap Work?

A grease trap operates based on a simple principle:

1. Wastewater containing grease enters the trap through an inlet pipe.

2. Heavier solid particles settle at the bottom.

3. Grease, being lighter than water, floats to the surface and is retained.

4. The filtered water exits through the outlet pipe.

Benefits of Using a Grease Trap

• ✅ Prevents Clogs: Reduces grease buildup in drainage pipes.

• ✅ Environmental Protection: Minimizes water pollution caused by grease.

• ✅ Cost Savings on Maintenance: Reduces the need for frequent pipe repairs.

• ✅ Easy Installation: Suitable for a wide range of applications, from households to industrial use.
