Swinging self-cleaning screen bars the Hobas CSO Chamber and their physical properties

Original language description

This paper deals with the design of the suitable shape of the swinging rods in the Tube overflow chamber (CSO HOBAS CHAMBER), in order to support the self-cleaning effect of the screen bars. The self-cleaning effect is caused by the free ends of the rods, which are swinging in the 45° range and freely vibrating in the stream. By oscillation, the settled dirt is released into the lower part of the CSO, from where it is subsequently discharged to the WWTP. The main objective of the research was to find suitable shapes of swinging rods so that the self-cleaning effect of the screen bars could be supported at different rod lengths. The measurement was carried out on a physical model made in 1 : 1 scale and was captured on a high-speed camera. The design criteria for swinging screens on CSO HOBAS CHAMBER of different sizes was established after analysis of created slow footage.
