Grease separator or grease trap installation is used in the catering industry to prevent a build up of grease and liquefied fats from solidifying and blocking the flow to the drainage system.
Therefore a grease treatment system should be installed by restaurants and catering establishments to help and support the drainage system.
A grease separator/trap installation is particularly important in kitchens and processing plants where more than 30 meals per day are served regularly and grease / bi products are discharged into the foul drainage system.
The new European design standard for a grease separator or grease trap installation is EN1825 which stipulates that in order to calculate the correct size (or Nominal Size [NS]) of a grease trap or grease separator, 4 major factors are calculated:
- Influence of cleaning and rinsing agents used.
- Density of grease/oils to be separated or trapped.
- Maximum temperature of water.
- Maximum flow rate of water.
