The job of the EUROPELEC cantral drive thickener is to thicken sludge from municipal or industrial wastewater treatment plants. It can be used in small or medium-sized installations.
Effluent is channelled to the centre of the tank in the influent well where it is spread evenly and without turbulence over the thickening zone. The clean effluent is collected over a saw toothed outlet weir. Vertical pickets attached to the drive shaft are used for removing gas from and thickening the sludge. The thickened sludge is guided to the centre of the tank by adjustable bottom scrapers. From the sludge well, they are carried to the final treatment stage by hydrostatic pressure or pumping.
The thickener is designed for tanks 3 to 13 m in diameter.
