Fine Drum Screens are used in both municipal and industrial applications, as well as for the pretreatment in MBR plants. The machine screens, washes, conveys, and dewaters screenings all in one unit, thus eliminating the need for multiple pieces of equipment.
Fine Drum Screens consist of a rotating drum screen, a conveyor screw, and a compaction zone. Depending on the application, the fine screen drum can be made up of a set of steel bars – in which case the distance between the bars determines the desired slot width – or of a perforated sheet filter. The cylindrically shaped drum can be placed inside a channel or a fabricated tank.
