These separators have a circular bottom. They are manufactured by simultaneous moulding of fiberglass with polyester (GRP) and they are very economical.
Their dimensions are reduced and normally their installation is made underground and they are supported on a flat level concrete bench (Installation Instructions).
The capacity of the tanks will be established according to the number of meals which are serviced through. Bupolsa has a range of capacities standardized by the manufacturing process counting on the following dimensions:
| Cilindric Grease Separator | |||
| Capacity (litres) | Meals | Ø (mm) | Height (mm) |
| 1.000 | 500 | 1.120 | 1.370 |
| 2.000 | 1.000 | 1.610 | 1.320 |
| 3.000 | 1.400 | 1.610 | 1.890 |

The grease separator is based on the difference in specific weights between water and grease. The water enters the intermediate part of the tank with a loss of velocity of the effluent, which first allows a separation of solids and, in turn, a separation of greases and detergents, which are captured on the surface of the separator. The effluent is collected at the intermediate part, thus avoiding the possibility of the fats being evacuated.
* It is very important that the canalization of kitchens and washing machines is separated from the sanitary one, for the installation of a grease separator.
* The effluent with fat content must be channeled independently of the sewage.
