Plumbing the BAGT® Grease Trap

The installation of the grease separator in the kitchen is usually done by a professional but can also be done with some plumbing bases. The installation of a grease trap is ideally under the commercial kitchen sink if the available volume is sufficient. It is necessary to provide at least 10 cm above the trap to open the lid and 15 cm on each side for connections. You will find the complete and detailed procedure for the installation of a grease interceptor in our video:

The grease interceptor is connected between the commercial sink and the drain to the sewer. The waste water inlet into the grease trap connects to the siphon under the professional sink.

It is interesting to set up a gooseneck siphon to avoid the risk of clogging a classic siphon. The basket is there to capture solid waste.

The grease trap has a PVC valve DN50 and a steel valve 1''1 / 4 for draining grease and a drain valve. A supplemental valve is provided for makeup water in the case of facilities away from the dive.

On the water outlet side, the grease trap is connected to the collective sewage system. The highest PVC valve DN50 (open during normal operation), blocks the water to allow the grease to drain to the front (steel valve 1''1 / 4).

The valve at the bottom is used when emptying the tank and fine waste settled at the bottom of the tank. It is best whenever possible to connect this outlet to drain the device whenever necessary.

If the grease trap is not installed directly under the sink, it is necessary to connect the water to the ½ '' connection with the supplied 15/21 valve. This valve always remains closed except when you want to evacuate grease.

Operation of the grease trap

Refer to the document ref: BAGT® grease trap operation xx - April 2017

The operation of the BAGT grease trap has been designed without PLC or electrical connection, to avoid the risk of failure, while being practical in its use. Wastewater (water, grease, solid waste) from the sink enters the grease trap basket. This 2mm mesh basket holds solid waste on top of the water to prevent dripping when removed. This basket should be emptied daily if possible; it is very easy to access.

Then the fatty substances are separated from the water by settling. In the case of BAGT®xxN, the operation of the grease arrestor is different. The fat separation process is optimized thanks to the lamellar system. These fats are recovered during the "draining fat", to be stored in a drum while waiting for their collection. These fats, collected by specialized companies, will be used as raw material in biodiesel production plants. Finally, pre-treated water can join the collective sewerage system.

A quick grease trap installation

The installation of the grease interceptor under the professional kitchen sink is simple and fast, less than half a day, often done by a professional. This type of grease trap does not require major installation work but in exchange requires regular maintenance. That's why we made it easy to install the BAGT®xxN Grease trap with our lamellar system.

In the case of larger models of underground grease traps, the installation of the grease interceptor is restrictive since the tank must be buried. The maintenance in this case is entrusted to a cleaning company, with a monthly rhythm according to standard NF EN 1825-2.

You will find some details on the standard NF EN 1825 on the study of the CNIDEP (National Center for Innovation for Sustainable Development and Environment in Small Business):

The installation of the grease traps can be subsidized, you can inquire with the Chambers of Commerce or Chambers of the Trades.
