What is the threshold amount of grease in effluent for which a grease trap is required?

The threshold amount of grease in effluent that necessitates the installation of a grease trap is indeed 50 mg/l. This standard helps in preventing excessive fat, oil, and grease (FOG) from entering the public sewer system, which can lead to blockages and the adverse effects that come along with it, including environmental damage and system inefficiencies.

When the concentration of grease in waste water exceeds this specified amount, it indicates that the potential for fouling in the sewage system becomes significant. Installing a grease trap that effectively removes grease before it reaches the main sewer line is crucial for maintaining optimal sewage operations and compliance with health and environmental regulations.

Understanding this threshold value ensures that commercial establishments, particularly those involved in food preparation or similar activities, are equipped with the necessary infrastructure to manage their wastewater responsibly and in accordance with local codes. This practice is pivotal for protecting wastewater treatment facilities from overloading and potential failures.
