How do you size an outside grease interceptor?
To size a Gravity Grease Interceptor with the flow determined in GPM you simply multiply the flow number by a detention time, 30 minutes (the time period normally excepted for the grease to separate by buoyancy). Again with our 20 GPM example, the size would be 20X30= 600. A 600 Gallon size interceptor would be used.
Does a grease interceptor need to be vented?
Do grease interceptors need to be directly vented? Gravity Grease Interceptors (GGI) do require to be directly vented. A Hydromechanical Grease Interceptor (HGI) does not require to be directly vented unless specifically mandated by local code or by law.
What is the difference between a hydro mechanical grease interceptor and a gravity grease interceptor?
Hydromechanical grease interceptors (HGI or trap) are smaller devices that can be installed above or below ground, as well as outside or inside of a facility. Gravity grease interceptors (GGIs) are larger in-ground tanks, typically installed outside the facility.
How do you select a grease interceptor?
How to size your Grease Trap
- Measure your sinks.
- Convert the capacity from total cubic inches to gallons per minute (GPM) by dividing by 231:
- Add any additional appliances (optional)
- Determine the flow rate and drainage period.
- Select interceptor from the table below which corresponds with the flow rate calculated.
How big of grease trap do I need?
The Plumbing & Drainage Institute (PDI) recommends that all dish machines have their own grease trap. Here are some recommendations: 10-15 Gallon Capacity Dish Machine Tank: 15 Pound Grease Trap. 20-30 Gallon Capacity Dish Machine Tank: 20 Pound Grease Trap.
How do you install an oil interceptor?
Install interceptor in the building sewer line. The interceptor may be set on the floor, partially recessed in the floor, top flush with the floor, or fully recessed below the floor to suit piping and structural conditions. Anticipate sufficient clearance for removal of interceptor cover for cleaning.
How do I know what size grease trap I need?
Sizing a Grease Trap by Flow Rate:
- Measure your sinks.
- Convert the capacity from total cubic inches to gallons per minute (GPM) by dividing by 231:
- Add any additional appliances (optional)
- Determine the flow rate and drainage period.
What happens if you don’t clean a grease trap?
If you don’t clean your grease traps, local governments can fine your restaurant. This is a financial consequence of not scheduling this cleaning service. Keep your grease trap clean as possible. This prevents plumbing problems, retains employees, and helps you avoid potential lawsuits.
How does an oil interceptor work?
Basically, oil interceptors work by separating the oil from the water. They function as a trap for rainwater runoff from different sources where oil is present on the surface, and prevents the oil from polluting the soil and the water courses.
