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 grease trap works by allowing wastewater to flow through a chamber where FOG rises to the surface and solid waste settles at the bottom. Regular maintenance, including cleaning and emptying, is essential to ensure the grease trap functions effectively and complies with local regulations regarding wastewater management.
