Which type of interceptor requires an orifice plate?

The type of interceptor that requires an orifice plate is the grease interceptor. Grease interceptors are designed to capture and separate grease and fats from wastewater before it enters the sewer system. The use of an orifice plate in a grease interceptor serves a crucial function by creating a restriction in the flow, which helps to control the flow rate and allows for adequate retention time within the interceptor. This retention time is important for the separation process, as it ensures that grease and oils have sufficient time to rise to the surface and be captured effectively.

The orifice plate helps manage the flow and provides a consistent discharge flow, which is essential for the efficient operation of the interceptor. This design ensures that the systems can handle varying flow rates without disrupting the separation of grease, thereby maintaining the functionality of the interceptor.

While other types of interceptors, such as sediment and stormwater interceptors, may have specific design features and functions, they typically do not require orifice plates like grease interceptors do. Each type of interceptor is designed to handle different materials and wastewater components, making the inclusion of the orifice plate specific to grease management in plumbing systems.
