How Does a Grease Trap Work?

A grease trap works by using gravity to separate FOG from the wastewater. When wastewater enters the trap, it slows down, allowing the FOG to rise to the surface. The FOG is then trapped by a series of baffles, while the water is allowed to flow through to the sewer system.

Over time, the FOG builds up in the trap, reducing its capacity and effectiveness. When this happens, the trap must be emptied and cleaned to ensure that it continues to function properly.

Maintaining a Grease Trap

Maintaining a grease trap is essential to ensure that it continues to work effectively and efficiently. Here are some tips for maintaining your grease trap:

Regularly empty the grease trap - How often you need to empty your grease trap will depend on the size of the trap and the amount of FOG generated by your business. Generally, it is recommended that grease traps be emptied and cleaned every 30 to 90 days.

Scrape and clean dishes before washing - One of the best ways to reduce the amount of FOG that enters your grease trap is to scrape and clean dishes thoroughly before washing them. This will remove any excess grease and food particles that could clog the trap.

Use biodegradable detergents - Using biodegradable detergents and cleaning products can help reduce the amount of FOG that enters your grease trap.

Train your staff - Proper training can help your staff understand the importance of maintaining your grease trap, as well as how to properly scrape and clean dishes and use cleaning products.

Troubleshooting a Grease Trap

Despite regular maintenance, grease traps can sometimes experience problems. Here are some common issues that can occur, as well as tips for troubleshooting them:

Foul odors - If your grease trap is emitting foul odors, it may be a sign that it needs to be cleaned. Emptying and cleaning the trap should resolve this issue.

Slow drainage - If water is draining slowly from your sink, it may be a sign that your grease trap is full. Again, emptying and cleaning the trap should resolve this issue.

Blockages - If you experience frequent blockages in your drain, it may be a sign that your grease trap is not functioning properly. In this case, you may need to have your trap inspected and repaired.

Overflow - If your grease trap overflows, it can cause serious environmental pollution and health hazards. If you experience an overflow, you should immediately contact a professional to repair the trap.
