Fats, oils, and greases (FOG) pose significant challenges to wastewater treatment systems primarily due to their tendency to solidify and accumulate, leading to blockages in pipes, pumps, and other equipment. These blockages can disrupt the normal flow of wastewater, thereby reducing the efficiency of the entire treatment process.

Moreover, FOG can create films on the surface of wastewater, which interfere with essential biological processes by limiting oxygen transfer and reducing the availability of nutrients for microorganisms responsible for breaking down organic matter. This disruption can result in suboptimal treatment performance, leading to higher levels of pollutants in the effluent.

In addition to mechanical issues, the presence of high concentrations of FOG can create an imbalance in the microbial community, further compromising the biological treatment processes that rely on specific organisms to effectively degrade waste. As a consequence, managing FOG is critical to maintain the health of wastewater treatment systems and to ensure compliance with environmental regulations.
