Grease Trap Sizing Calculator
The Grease Trap Sizing Calculator finds the design flow, liquid capacity, and cleaning interval for a kitchen grease interceptor. Example: for a commercial kitchen with two 30 L/min fixtures serving 200 meals/day, Design flow = 45 L/min, Liquid capacity = 113.6 L, Cleaning interval = 1 days (per PDI G-101 | DENR DAO 2016-08).
How it works
Computed from your inputs per PDI G-101 | DENR DAO 2016-08.
