Each installation is unique. Ensure that the grease interceptor you install is the correct size for the application.
The growth of fats, oils and grease (FOG) interception programs has increased the awareness and need for proper grease management. The following article outlines the available sizing methods for hydromechanical grease interceptors (HGI) as well as a recently adopted method for estimating the maintenance frequency based on the estimated grease production of the facility. HGI’s are sized and tested around volumetric flow rates, as reflected in the unit sizing, e.g. 25 gallons per minute (GPM).
