A grease trap is a plumbing device designed to intercept and retain fats, oils, and grease (FOG) from wastewater before it enters the main sewage system. It is commonly used in commercial kitchens, restaurants, and food processing facilities to prevent clogs and maintain proper drainage. By capturing these substances, grease traps help reduce the risk of sewer backups and environmental pollution. The operation of a grease trap relies on the principle of gravity. As wastewater flows into the trap, the lighter FOG rises to the top, while heavier solids settle at the bottom. Regular maintenance and cleaning are essential to ensure the effectiveness of a grease trap and to comply with local regulations regarding wastewater management.
