Rotary drum screen

July 1, 2010




Used to remove solid materials from waste streams at high rates, the Munson 24 RDS 24 self-cleaning rotary drum screen contains a 24-in. diameter by 24-in. long rotating cylinder constructed of wedgewire screen. 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. Intended for applications in which solids must be removed from slurries in high volumes, the unit is also available in models with drums 24 in. in diameter and 36-, 48-, 50- and 72-in. lengths, and with drums 36 in. in diameter and 96- and 120-in. lengths. Capacities range from 200 to 4,650 gal./min.
