How an Externally Fed Rotary Drum Screen Operates
Externally fed rotary drum screens work through a seamless mechanical self-cleaning process. Here’s an overview of how they function:
-
Influent Introduction:
Wastewater or slurry is fed externally onto the rotating drum’s surface. The liquid flows through the precision-engineered wedge wire apertures, allowing smaller particles and liquids to pass through. -
Solid Separation:
Larger suspended solids remain on the drum’s surface and are gently transported to the discharge end by the drum’s slow rotation. -
Self-Cleaning Process:
A spray cleaning system or mechanical brushes help to remove debris from the drum’s surface, maintaining high filtration efficiency without clogging. -
Continuous Operation:
The system operates automatically, ensuring consistent filtration and minimal downtime, which is ideal for high-capacity applications.
