         Rotary drum filter screen should be installed in water channel at 35 degree angle. Waste water enters into drum though rotary drum inlet, and flows though side screen gap of rotary drum. Suspended solids in waste water will be withheld in rotary drum. Cleaning arm with rabble blade cleans screen gap when making circular motion, and fetches solids from screen by rabble blade. Wastes will be clean away from rabble blade by wash water and baffle, and dropped into screw press. Wastes will be dewatered by shrinking screw pitch during transportation, and extruded and dehydrated in the top compression zone. Extra water will reflow into water channel and wastes will go to container or follow-up equipment for next treatment.
