Which function is primarily associated with grease traps?

• A. Chopping solids in wastewater
• B. Intercepting and retaining grease in wastewater
• C. Filtering dirt and sand from water
• D. Storing excess sludge

Answer: (B)

The primary function of grease traps is to intercept and retain grease in wastewater. Grease traps are designed to capture fats, oils, and grease (commonly referred to as FOG) that are generated from cooking activities in commercial kitchens or food service establishments. As wastewater flows through the grease trap, the lighter grease and fats rise to the top due to their lower density compared to water. This separation process allows the cleaner water to flow out of the trap while the grease accumulates at the top and is retained within the trap, preventing it from entering the septic system or municipal sewer system. Grease traps are critical for maintaining proper sewage system function, as excessive grease can cause clogs and backups, leading to costly repairs and environmental hazards. Therefore, the correct answer highlights the primary role of grease traps in managing waste products effectively.
