1 Application range
Bar screen is a universal separator of
insoluble solids from fluids. It can be used in waste water treatment plants,
water treatment plants or pumping stations. Usually it is installed on the
inlet canals as the pre-treatment equipment, from where it lifts up entrapped
substances above the canal edge or to another floor to a height necessary for
further liquidation (container, screw conveyor, screenings press, etc.).
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
wheels.
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.
