What are oil and grease traps and skimmers?

Oil and grease are major contaminants in wastewater that can cause significant environmental pollution. They can clog pipes and cause damage to equipment in sewage treatment plants. To prevent these problems, oil and grease traps and skimmers are used in sewage treatment plants to separate and remove oil and grease from the wastewater.

In this blog, we will discuss what oil and grease traps and skimmers are, how they function, the difference between them, and which one is better.

Oil and Grease Trap:

An oil and grease trap is a device that is used to separate oil and grease from wastewater. It is typically installed in the influent line of a sewage treatment plant. The wastewater flows into the trap, and the oil and grease separate from the water due to their lower density. The separated oil and grease are then removed and disposed of separately.

Oil and Grease Skimmer:

An oil and grease skimmer is another device used to remove oil and grease from wastewater. It is typically installed in the effluent line of a sewage treatment plant. The skimmer uses a rotating drum or belt to skim the surface of the water and collect the oil and grease. The collected oil and grease are then removed and disposed of separately.

Function of Oil and Grease Trap:

The function of an oil and grease trap is to remove oil and grease from wastewater before it enters the sewage treatment plant. The wastewater flows into the trap, and the oil and grease separate from the water due to their lower density. The separated oil and grease are then removed and disposed of separately. The remaining wastewater is then treated in the sewage treatment plant.

Function of Oil and Grease Skimmer:

The function of an oil and grease skimmer is to remove oil and grease from the effluent water leaving the sewage treatment plant. The skimmer uses a rotating drum or belt to skim the surface of the water and collect the oil and grease. The collected oil and grease are then removed and disposed of separately. The remaining water is then discharged into the environment.

Difference between Oil and Grease Trap and Oil and Grease Skimmer:

The main difference between an oil and grease trap and an oil and grease skimmer is their location and function. An oil and grease trap is installed in the influent line of the sewage treatment plant, and its function is to remove oil and grease from the incoming wastewater before it enters the sewage treatment plant. An oil and grease skimmer, on the other hand, is installed in the effluent line of the sewage treatment plant, and its function is to remove oil and grease from the treated wastewater before it is discharged into the environment.

Which One is Better:

Both oil and grease traps and skimmers are effective in removing oil and grease from wastewater. However, their effectiveness depends on the specific needs and requirements of the sewage treatment plant. Oil and grease traps are typically more effective in removing large amounts of oil and grease, while oil and grease skimmers are more effective in removing smaller amounts of oil and grease.

Conclusion:

Oil and grease are major contaminants in wastewater that can cause significant environmental pollution. Oil and grease traps and skimmers are used in sewage treatment plants to remove oil and grease from wastewater. While both are effective, their effectiveness depends on the specific needs and requirements of the sewage treatment plant. By using these devices, sewage treatment plants can prevent environmental pollution and operate in an environmentally responsible manner.
