Fats, Oils & Grease (FOG)

Fats, oils and grease—commonly referred to as FOG—are some of the trickiest things to treat in wastewater. Fats, oils and grease can build up and become what are called fatbergs. Fats, oils and grease also play an important role in wastewater treatment plants, particularly those that capture biogas to generate electrical an thermal energy. These processes often use FOG from outside sources like restaurants and industrial facilities to generate enough gas to meet an energy efficiency goal. The ultimate goal of such a process is net zero, in which a water treatment plant can generate enough energy from biogas to eliminate its energy expenses.
