PICC series. The thickener bridge with central drive can be installed in different sizes of reinforced concrete tanks. Its purpose is to thicken and prepare sludge from the decanters for subsequent treatment
The in-flow of sludge is diverted by the settling cylinder to optimize thickening; special pegs turn very slowly to expel any air still in the sludge. Bottom scrapers remove the accumulated sludge for collection in the central hopper, where it is extracted through pipes.
The clarified water flows in the peripheral channel.
