Rotary Drum Screen

October 28, 2008
This self-cleaning rotary drum screen separates solid debris from wastewater at high rates with low-energy usage. The unit contains a rotating cylinder constructed of wedge wire screen with a stationary doctor blade on the outside of the cylinder and an internal spray line. Effluent discharges from a head box, overflows a dam, and flows onto the outside of the rotating cylinder, allowing water to pass through the wedge wire into the cylinder. The doctor blade scrapes sludge and debris collected on the outside of the cylinder, while an internal spray line dislodges particles blinding the screen. The separator is intended for sewage treatment, processing of pulp and paper, rendering, pelletizing, and other applications in which solids must be removed from slurries in high volumes.
