Passavant® Multi-Rake Bar Screen


The Passavant® Multi Rake Bar Screens KUR from Aqseptence Group are machines which are developed with the know-how of experience for decades in the construction of sewage treatment plants. Innovative production processes have succeeded in creating a top quality product which is characterized by its economic efficiency and excellent cleaning performance.

How it works

This is achieved by the utilization of flow-optimized screen bar profiles, which are tailored to hydraulic requirements, together with variably adaptable cleaning elements which can be adjusted, both in type and number, to suit the respective transport task and the requirements of the cleaning cycle.

The cleaning cycle starts as soon as the drive is activated, in order to reduce the difference in water levels caused by screenings accumulating in the bar rack. During the ascending cycle, such screenings are completely removed by the cleaning elements which
penetrate into the screen bars. The screenings are then collected and conveyed to the discharge point from where they are pushed, by means of an automatic stripping device, down a discharge chute to the screenings collection tank, conveyor belt etc. The screen cleaning cycle is repeated until the difference in water levels has been completely removed.


  • Low maintenance, low wear and tear due to:
    • Individually replaceable sprocket teeth on the drive unit
    • Maintenance-free stainless steel roller chain
    • No bearings below the waterline
    • The swiveling chain guide assembly ensures easy accessibility for KUR-S
    • Blockade monitoring and reverse operation to remove obstacles in the bar rack
    • Short cleaning cycle time due to multiple revolving cleaning elements
