Externally Fed Rotary Drum Screens

EXTERNALLY FED ROTARY DRUM SCREENS

Externally fed rotary screen systems are considerably fine screens mounted to the pipeline, which are operated on the basis that the floating solid substances contained in the wastewater are kept outside the screen. They are drum screens used for the separation of wastes from domestic treatment plants, but also different kinds of process wastes from industrial wastewater treatment plants. There are two types of screens used in externally fed rotary drum screens as “perforated plates” and “wedge wires”. Perforated plates provide a high capture rate of materials bigger than the perforation size. On the other hand, wedge wires minimizes risk of clogging and maximizes permeability ratio with the V-shaped profile.
