Abstract

A device for removing impurities from a liquid, preferably sewage, includes a pivoted filtering drum having a filtering surface, equipped with a drum drive operatively connected to the filtering drum to turn the filtering drum around a rotating axis. A cleaning system cleans the filtering surface and has a guide and a spray nozzle arrangement movable back and forth along the guide. Cleaning liquid can be sprayed on the filter surface. The spray nozzle arrangement may include at least one carrier movable back and forth along the guide and at least one spray nozzle mounted on the carrier so that it can be moved around an axis. A related method for cleaning a corresponding device is disclosed.
