What do fats, oils, and grease content measurements indicate in wastewater?

The measurement of fats, oils, and grease (FOG) content in wastewater is an important factor in assessing the characteristics of the waste being treated. A level above 25 mg/l is significant because it generally indicates that the wastewater is of high strength. High-strength wastewater can lead to operational issues in treatment facilities, as it often requires more energy and resources to treat due to its higher organic loading. Monitoring these levels helps facilities anticipate the treatment needs and gauge the potential impact on the system, including possible blockages and inefficiencies in treatment processes.

In this context, recognizing that a FOG content level exceeding 25 mg/l signals high strength wastewater is crucial for maintaining effective treatment operations and adhering to regulatory limits.
