Grease traps are an important part of every food establishment, such as a restaurant or cafe.

Grease traps are an important part of every food establishment, such as a restaurant or cafe. They prevent fats, oils, and greases, commonly referred to as FOG, from entering their city’s drainage system. These, often essential parts and ingredients of cooking and food, can cause significant issues if they get into the drainage, such as clogging our infrastructure or ending up in the water where they damage our ecosystem.  Let Hugo Plastics explain how grease traps work in eliminating these problems from FOG.

How can grease traps separate FOGs from water?

To answer this question, it is essential to know that due to the low density of grease, it floats on water. The density of water is approximately 1.000g/cm3, whereas that of oils and fats is only between 0.850 and 0.950 g/cm3. Because of this, the FOG does not mix with water and floats on top whenever they come into contact with each other. However, when water and FOG are both warm, an emulsion can form between the two substances. A grease trap is required to separate the emulsion and ensure no FOG enters our wastewater system.

To prevent the water and FOG from entering pipelines, grease traps are installed into commercial kitchens that work to fully separate these two liquids and “trap” the grease. The grease trap with its internal baffles will retain and slow down the flow of water and FOG, so they can cool down and separate. Grease traps are connected to kitchen sinks and other wastewater.  The solid FOG then settles at top of the tank, with cleaner wastewater being allowed to flow through the outlet chamber into the city’s wastewater system.

Why are grease traps important?

Grease traps are a legal requirement across New Zealand at any restaurant or commercial food preparation area. If they are not installed, FOG would get into wastewater systems and cause significant disruptions with blockages across our infrastructure.  Owners might often find it challenging to come across a grease trap that fits perfectly into their premises and does not take away the much-needed space in a restaurant. Hugo Plastics manufactures custom-made and sized passive grease traps for the whole of New Zealand to ensure that all places find the perfect product for their needs.
