How do Circular Bar screens work?

This is a separation unit used to capture floating impurities. Water containing solid particles flows through the inlet pipe into the inner space of the unit, where it passes through the bar screen. Here the screenings are effectively separated. The screen gradually becomes clogged with screenings, which causes the level to rise. Once the start-up level is reached, the probe switches and the device starts automatically. The captured screenings are lifted into the discharge chute, from where they fall, for example, into a prepared bin or container. Water free of floating impurities larger than the opening size flows under the bar screen to the outlet and to a possible next treatment stage. After the screenings are lifted out, the screen throughput is restored, the water level inside the unit drops, and the sweeping stops. The screen gradually becomes clogged again with floating impurities and the whole cycle repeats. The inflow of raw water is not interrupted at any point during the process.
