What is a grease separator?

500 L grease separators

Wastewater from food processing activities (industrial kitchens, restaurants, some agri-food industries, etc.) contains animal and vegetable greases and oils. Before discharging this wastewater into the treatment system or the local sewage network, grease separators must be used to prevent fats and oils from solidifying and clogging the system pipes.  

Our separators are manufactured with high density polyethylene (HDPE) by rotomolding, always ensuring watertightness and a long service life.  

Grease separators can only receive grey wastewater. If installed in conjunction with wastewater treatment systems, it is mandatory to separate faecal wastewater from grey wastewater. Once the fats, oils and greases have been separated, the two systems can be relinked again.  

Examples of applications:

  • hotels 
  • restaurants and bars 
  • cafés 
  • agri-food industry 
  • schools 
  • hospitals and health facilities 

How do the Rewatec grease separators work?

The Rewatec grease separators are intuitive, easy to operate and require no energy input. The separation works on the basis of different densities of liquids over a given period of time in the tank. As fats and oils are less dense than water (1 g/cm3) and don’t mix with it, they thus float on top of the water. The separated clear water then flows to the next stage of the installation.  

Premier Tech offers a wide range of flow rates and volumes: 

  • Flows from 0.5 L to 30 L/s 
  • Volumes from 72 L to 15,000 L

Moreover, if you want to avoid unpleasant surprises in your installation, we have a grease level detection alarm to install in any of the Premier Tech models. 

Grease separators for domestic or industrial use
  • Solution to bury with decanter (up to 20 L / s and 8,000 l)
Grease separators for domestic or industrial use
  • Solution to put under the sink (up to 0.75 l / s and 200 L)

Maintenance recommendations

Premier Tech recommends that you follow the maintenance instructions according to the model installed. Protect your investment by performing regular checks to help extend the service life of the system and maintain your warranty. 

To empty the tank all you have to do is open the lid and pump out the accumulated oil and grease with a hose. The interior walls have smooth surfaces for easy cleaning, if necessary.
