How do fats, oils, and grease (FOG) impact wastewater treatment processes?

Fats, oils, and grease (often abbreviated as FOG) have significant negative impacts on wastewater treatment processes. When FOG enters the wastewater system, it can accumulate in pipes and equipment, leading to blockages. These blockages can impede the flow of sewage, resulting in backups or overflows, which pose health hazards and environmental risks. Additionally, the presence of FOG interferes with the efficiency of biological treatment processes. For example, the presence of high levels of fats and oils can inhibit the activity of microorganisms that are essential for breaking down organic matter in the treatment process.

Overall, the detrimental effects of FOG are well-documented, making their management a crucial aspect of wastewater treatment. It's important to effectively capture and remove FOG from wastewater systems to maintain optimal operation and ensure the integrity of the treatment processes.
