Grease-laden water treatment

Restaurants, collective kitchens, processing workshops or the food industry: discover our high-performing biological solutions suited to treating your grease-laden water.

Grease-laden water

Grease-laden water is wastewater containing fats of animal or vegetable origin, often from professional kitchens (restaurants, canteens, caterers, etc.), food industries and domestic installations.

Grease-laden water accounts for a significant share of wastewater discharged. Poorly managed, it can cause major nuisances: blocked pipes, bad odours, pollution of natural environments and overloading of treatment plants.

That is why treating grease-laden water is a key step in the wastewater management chain.

🌍 Why treat grease-laden water?

Once cooled, fats tend to solidify, blocking pipes and disrupting the proper functioning of sewer networks.

Discharging grease-laden water directly into pipes or the sewer network can cause blocked pipes, bad odours, malfunctions in treatment plants (fats disrupt biological treatment), pollution of natural environments, if the fats are not properly intercepted.

Treating the fats contained in water, with a view to removing them from the water, requires specific treatment because fats are not soluble in water.

Treatment at source is therefore not only recommended but mandatory in many cases.

How to treat grease-laden water?

Treatment is carried out in several ways, the main one being the physical separation of fats using a grease trap (or grease separator). It is the most common equipment.

Bio-treatment: a high-performing, suitable biological solution

In some cases (food industry, large volumes of grease), additional treatments can be put in place.  These biological treatments provide reliable solutions, as an alternative or a complement, for sanitation and the treatment of grease-laden water.

The biodegradation of fatty waste (bacteria capable of breaking down fats) applies to your grease trap or to treatment plants.

These products break down fats and make it easier for other treatment techniques to follow.

Towards recovering fats

Instead of simply being eliminated, the fats from treatment can be recovered:

  • As biogas via methanisation,

  • As fuel (biodiesel),

  • As compost, in some cases.

This approach is part of a circular economy and sustainable management of organic waste.

🏛️ A strict regulatory framework

Regulations require food service and food industry professionals to ensure:

  • The installation of a suitable grease separator,

  • Regular emptying by an approved company,

  • Traceability of the fatty waste collected.

Individuals are generally not subject to these obligations, but in areas not connected to the main sewer (individual sanitation), a grease trap is sometimes required upstream of the septic tank.

Conclusion

Treating grease-laden water is an essential step to guarantee the proper functioning of sewer networks and protect the environment.

Thanks to simple equipment such as grease traps or innovative systems such as bio-treatments, it is possible to manage grease-laden discharges effectively. For professionals and local authorities alike, good management of grease-laden water is both a regulatory obligation and an ecological opportunity.
