Wastewater enter into clarifier through the central steady flow tube, the central drive sludge scraper bridge fitted with a central shaft with arms and scraper blades that rotate in clockwise direction and thus convey the debris (sludge, etc.) towards the middle of the reinforced concrete tank, from where sludge is discharged.

On request, the machine can be fitted with the suspended solid extraction mechanism, which thanks to the bridge rotation, conveys the foams (oily and light parts present on the water surface) to the scum trough fixed to the reinforced concrete tank wall. The clean water flows through the V-notched weirs and flows into a discharge channel.
