Model 24 RDS 24 rotary drum screen

The self-cleaning Model 24 RDS 24 rotary drum screen removes solid materials from waste streams at high rates. The rotating cylinder is constructed from wedgwire screen that is available in seven orifice sizes. Cylinder dimensions include either 24- or 36-in. dia., with lengths ranging from 24 to 120 in., giving operators the option for throughput capacities ranging from 200 to 4,650 gal/min. The effluent stream discharges from a head box, overflowing a dam and flowing onto the outside of the rotating cylinder, allowing water to pass through into the cylinder. A blade scrapes sludge and debris collected on the outside of the cylinder, while an internal spray line dislodges particles blinding the screen. This unit is suited for use in food, pulp-and-paper, rendering, sewage, palletizing, and other applications in which solids must be removed from slurries in high volumes.
