How To Calculate Calculate Grease Interceptor size:

The size of a grease interceptor required for a 2-bowl sink and a 3-bowl sink would depend on several factors, including the flow rates of the sinks, local regulations, and the type of establishment.

Here’s a general approach to calculating the required grease interceptor size for these scenarios:

Determine Flow Rates:

Calculate the flow rates of the 2-bowl sink and the 3-bowl sink separately. This is typically measured in gallons per minute (GPM) or gallons per hour (GPH). You can usually find information about the flow rates in the sink’s specifications.

Calculate Total Flow Rate:

Add the flow rates of the 2-bowl sink and the 3-bowl sink to get the total flow rate that the grease interceptor needs to handle.

Check Local Regulations:

Look into local plumbing and building codes to find any specific requirements for grease interceptor sizing. Some areas may have specific guidelines based on the type of establishment, flow rates, and other factors.

Retention Time:

Determine the desired retention time for your grease interceptor. Retention time is the duration that wastewater remains in the interceptor, allowing the grease to separate. Common retention times range from 30 minutes to 90 minutes, but this can vary based on local regulations and the type of establishment.

Use Sizing Formula:

Use the following formula to calculate the required grease interceptor capacity: Interceptor Capacity=Total Flow Rate(GPM)×Retention Time(minutes)

Plug in the total flow rate you calculated and the chosen retention time to determine the required capacity in gallons.

Select the Grease Interceptor Size:

Based on the calculated capacity, choose a grease interceptor model that can accommodate the required size. Grease interceptors come in various sizes and configurations to meet different needs.

Consult Local Authorities or Experts:

If you’re uncertain about local regulations or need assistance with the calculations, consider consulting local plumbing authorities, engineers, or professionals who are experienced with grease interceptor sizing.

Remember that this is a general guideline, and the specific requirements can vary based on your location, establishment type, and local regulations. Always ensure compliance with local codes and seek professional advice when needed.
