A screen system that can be internally or externally fed influent is the ___________?

A rotary drum screen is designed to handle influent from both internal and external feeding sources, offering versatility in wastewater treatment applications. This type of screen employs a rotating cylindrical mesh that filters solids from the liquid as it passes through, effectively removing debris and larger particles before they enter downstream processes. The design allows for a continuous operation, making it efficient in managing variable flow rates and loads.

The internal feeding aspect refers to the ability to collect influent from within the treatment system itself, while external feeding allows the screen to accommodate influent that may come from different directions or external sources. This flexibility is crucial for adapting to various installation scenarios and operational needs in wastewater treatment facilities, thus enhancing the overall efficacy of the solids removal process.

Other screen types may have specific applications or designs that limit their feeding configurations, which is why they do not possess the same level of adaptability as the rotary drum screen.
