Grease interceptors recently have been receiving more attention as regulators in many municipalities impose more stringent regulations to reduce the amount of fats, oils, grease and food solids found in city wastewater collection systems.
Restaurants, industrial food facilities and other commercial food-service establishments are significant sources of FOG because of the amounts produced from cooking, food preparation and cleanup work. More regulators are beginning to echo the message: “FOG isn’t just limited to what you cook, it has a lot to do with what you wash (i.e. washing pots, pans and dirty dishes).” FOG sticks to the sides of kitchen plumbing pipes and eventually finds its way into sewers and hardens inside pipes.
