What does the term "gravity" imply regarding a grease interceptor?

The term "gravity" in relation to a grease interceptor primarily refers to the separation of materials based on their density. Grease interceptors operate on the principle that grease and oils are lighter than water; therefore, they rise to the surface and separate from the wastewater. This separation is largely influenced by gravity, allowing the grease and other floating materials to accumulate in a specific chamber while the denser wastewater continues to flow through the system.

Understanding this principle is crucial for the effective design and operation of grease interceptors, as proper sizing and installation rely on the efficient use of gravity to facilitate the removal of fats, oils, and greases from wastewater before it enters the sewer system. This not only helps in maintaining plumbing systems but also contributes to preventing environmental blockages and pollution.

Options relating to mechanical systems, water movement independent of forces, or installation requirements based on plumbing code are not directly related to the fundamental working principle of gravity in grease interceptors. Instead, those aspects refer to other operational and regulatory prerequisites.
