Abstract

A device for purification of liquid media such as waste water shows a housing in the form of a trough with an inlet (18) and three outlets (20, 19, 21) for screenings, a strained medium and thickened sludge, respectively. Between the inlet (18) and the first outlet (20) a strainer drum (25) is rotatably arranged, the inside of which is associated with the second outlet (19). On the strainer drum (25) radial screening members (35) are arranged which, on one hand, project during the rotation of the drum through a cleaning screen in order to bring along coarse impurities along this from the inlet (18) to the first outlet (20) and, on the other hand, serve to thicken sludge collected at the bottom of the housing which can then be removed through the third outlet (21).
