2 Description of operation
Floating particles are separated from waste
water flowing through screen by a filtration belt that lifts the separated
particles to a discharge chute while the screenings-free water flows on to
another stage of treatment. Special design and guiding of belt elements (rakes)
ensures an automatic separation of screenings from the belt. The belt is driven
by an electric gearbox through a chain transmission and shaft of belt guiding
The belt stretching can be adjusted. Screen
drive can also be installed directly on the shaft on either side of the frame
according to spatial layout.
Any screw conveyor can be installed to a
wall opening so that screenings are transported to a container or a flat truck
standing outside the building.
