Grease interceptors shall have the grease retention capacity indicated in Table 18-29-1003.3.5.1 for the flow-through rates indicated.
Total Flow-Through Rating (gpm) | Grease Retention Capacity (pounds) |
Total Flow-Through Rating (gpm) | Grease Retention Capacity (pounds) |
4 | 8 |
6 | 12 |
7 | 14 |
9 | 18 |
10 | 20 |
12 | 24 |
14 | 28 |
15 | 30 |
18 | 36 |
20 | 40 |
25 | 50 |
35 | 70 |
50 | 100 |
75 | 150 |
100 | 200 |
For SI: 1 gpm = 3.785 L/m, 1 pound = 0.454 kg.
a. For total flow-through ratings greater than 100 (gpm), double the flow-through rating to determine the grease retention capacity in pounds.
