What is a grease separator?
Wastewater from industrial kitchens, restaurants, and some agri-food industries contains fats and oils. To prevent these materials from clogging downstream pipes, wastewater must first pass through a system that separates and retains grease.
Grease separators can only receive greywater — wastewater from sources other than toilets and urinals. If they are installed in conjunction with wastewater treatment systems, greywater must be separated from other streams. Once fats, oils, and greases have been retained, the two systems can be linked again.
Our grease separators are the ideal solution for this specialised need. They are rotomoulded with high-density polyethylene (HDPE) to ensure a watertight design and a long service life.
The Rewatec grease separator is designed in accordance with EN 1825 and achieves an output concentration of less than 15 mg/L.

How do our grease separators work?
Our grease separators are intuitive, easy to operate, and require no energy input.
Separation works on the principle that liquids with different densities react in predictable ways. Fats and oils do not mix with water because they are less dense (1 g/cm3). As a result, they eventually float to the top of wastewater. When this happens, clarified wastewater flows downstream for further treatment.
We offer grease separators for a wide range of flow rates and volumes:
- flows from 0.5 to 30 L/s
- volumes from 72 to 15,000 L
To avoid unpleasant surprises in your system, we also offer alarms to detect high grease levels in all of our models.
- Solution to bury with a decanter (up to 20 L/s and 8,000 L)
- Solution to put under a sink (up to 0.75 L/s and 200 L)
Grease separator maintenance
Premier Tech recommends that you follow maintenance instructions according to the model installed. Protect your investment, maximise its service life, and maintain your warranty by having your system regularly inspected.
To empty your grease separator, simply open the lid and pump out the accumulated material with a hose. The tank's interior walls have smooth surfaces for easy cleaning, when necessary.
