FSM - Rotary Drum Screen
Waste water flows through a revolving drum, which is installed at an angle of 35°. The wastewater flows into the open end of the drum. Floating and suspended screenings are retained by the screen basket, which is available with a perforation or a wedge wire. The upper third of the drum is cleaned via a line of nozzles.
The screenings thereby separated out drop into the screw conveyor, which transports and compacts the screenings. The design ensures that the screen side to be cleaned is always in the upstream water, avoiding the “carry-over” effect.
Perforation size/Bar spacing of the screening area can be between 1 / 0,5 mm and 10 / 6 mm. Cleaning of the drum is effected by a spray nozzle bar and a brush. Drum and conveyor are driven by a geared motor. The FSM rotary drum screen could be installed directly into a channel or as an option into a tank.
