Rotary Drum Screen
Munson Rotary Drum Screens utilize a cylindrical drum constructed of wedge wire screen to remove solid materials from waste streams at capacities from 200 to 4,650 gal/min. (757 to 17,600 liter/min.). Effluent discharges from a head box, overflows a dam and flows onto the outside of the rotating cylinder, allowing water to pass through the wedgewire into the cylinder. A doctor blade scrapes sludge and debris collected on the outside of the cylinder, while an internal spray line dislodges particles blinding the screen.
TYPICAL APPLICATIONS
- Rendering plants to separate sludge
- Plastic extrusions cooling bath water to separate pellets
- Municipal wastewater sludge removal
- Pulp and paper sludge removal
- Separation of solids from any slurry in high volumes
