What is the function of a grease interceptor?

The function of a grease interceptor is to capture grease and solids from wastewater before they enter the main sewage system. Grease interceptors are essential in commercial kitchens and food service establishments where fats, oils, and grease (FOG) are produced in significant quantities. By trapping these substances, grease interceptors prevent them from clogging the sewer lines, which can lead to backups, costly repairs, and environmental issues. The design of a grease interceptor creates a separation process, allowing grease and solids to rise to the top or settle to the bottom, effectively cleaning the wastewater before it is discharged into the public sewer system. This process is critical for maintaining the efficiency of the plumbing system and complying with local regulations regarding wastewater management.
