          The grease trap prevents the introduction of substances that could damage or disrupt the functioning of the collective sanitation network. This specifically concerns fats and oils, whether of animal or vegetable origin, that are present in wastewater from the kitchen.
           
          Installing a grease trap is therefore essential in restaurants as well as for food industry professionals such as butchers, cafes, bakeries, pastry shops, caterers, etc.
           
          What is a grease trap?
          The grease trap is a device designed to retain at the source of their production a number of pollutants from culinary activities: fats, oils, and large waste. It is a gravity-operated device whose function is to block grease and debris. This separation process occurs upstream of the wastewater discharge into the sanitation network. The goal is to avoid polluting the network and blocking pipes.
           
          How does a grease trap work?
          The grease trap works as follows: the device is installed just after the wastewater drainage pipe. When wastewater enters the trap, fats and oils rise to the surface, while larger particles (like food scraps) settle at the bottom of the tank. The treated water is then discharged through a dedicated outlet into the pipes, leading to the sanitation network or the household septic tank.

          Sanigrease T24
          This system is suitable for installation in non-freezing conditions in a small kitchen. It is the mobile Sanigrease T24 grease trap, which can be easily placed under a professional sink or connected to a mobile dishwasher. Its total tank capacity is 24 litres, while the maximum grease volume that can be treated is 8 litres. Therefore, it is necessary to empty this separator daily and perform regular cleaning.
          FAQs

          Frequently Asked Questions

          • Both separate fats, oils, grease, and solids from kitchen wastewater, but they differ in capacity, configuration, automation, and intended duty. A compact trap may suit occasional or mobile use, while a separator is selected for larger or more continuous flows.

          • Restaurants, hotels, cafés, bakeries, caterers, food-processing sites, commercial kitchens, and other premises that discharge grease-laden wastewater should assess the need for a suitable trap or separator.

          • The interval depends on the model, capacity, grease load, and operating pattern. Compact units such as the Sanigrease T 24 require frequent attention, including daily emptying in the stated application.

          • Wastewater slows inside the separator so grease rises, heavier solids settle, and the separated water exits through the outlet. This reduces the amount of grease and debris entering downstream pipework.

          • Consider kitchen flow rate, number and type of appliances, operating hours, solids load, available space, cleaning access, and the applicable local requirements. Nominal size alone should not be selected without reviewing the installation conditions.

          • Some models are intended for indoor installation, while compact units may suit under-sink or mobile applications. The location must provide access for inspection, cleaning, emptying, ventilation, and safe connection to the drainage system.
