The screenings to be treated are conveyed directly from a bar screen or other stage in the sewage treatment line and dropped into the loading hopper of the machine. First they are rinsed on a sieve to get rid of organic slurry. Next, a screw conveyor transports the screenings to the dewatering press, where they are finally dewatered and compressed. The dewatered and compressed screenings free from organic content are conveyed outside.
