Polyethylene sand and grease traps

​​​​​​​Want to prevent fats, oils and grease (FOG) from entering your sewage system? A commercial grease trap is the solution. These simple plumbing devices can help to capture unwanted FOGs before they enter the main drainage system – and they could be exactly what you need to prevent blockages and boost the performance of your packaged pumping station.  

What is a grease trap?

A grease trap is a small plumbing device or receptacle. It is installed into the drainage system of a kitchen, laundry room or bathroom, where wastewater (containing FOGs) flows through on a regular basis. The grease trap, essentially, intercepts the wastewater – ‘trapping’ the FOGs and other solid particles, yet allowing clear water to pass through into the main sewage pipes.

How does a grease trap work?

As wastewater enters a grease trap, it separates into three layers. This is due to the force of gravity. FOGs are 10-15% less dense than water and, as a result, they rise to the surface and can be quickly trapped by the device. By contrast, solid particles weigh more than water and therefore sink (and settle) at the bottom of the tank. The middle layer is the remaining clear water. This is allowed to exit the grease trap via the outlet pipe – easily flowing through into the main sewage system.

Do I need a commercial grease trap?

FOGs can be highly problematic within a sewage system. Gradual build-up can lead to blockages in the internal pipework, resulting in expensive repairs and potential downtime for your business. Fats and oils also cause damage to wastewater treatment equipment – which is why, legislation is now heavily enforced and investing in a grease trap is more important than ever.

Grease traps can be used within a home or domestic setting. But they’re most commonly found in catering establishments and commercial settings – such as restaurants, cafés, takeaways, bars, and schools – where a large volume of wastewater (containing FOGs) is poured down the drain.
