Self-cleaning Drum Screen Separates Solid Debris from Wastewater

Munson Machinery Company's 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, pulp and paper, rendering, pelletizing and other applications in which solids must be removed from slurries in high volumes.
