Abstract

A purification device is described for waste waters polluted with coarse sinking material and floating material, such as for example abattoir effluent. The device comprises a drum screening machine having external feed delivery and a separating tank provided downstream of the screen undersize passages. In order to make the feed delivery to both parts of the device more even, the inlet to the separating tank is throttled to the design amount and both the inlet and the screen undersize passage are equipped with an overflow which leads to a holding tank equipped with a return pump to the screening machine. The return pump is controlled by mirror sensors.
