ABSTRACT:
A clarifier having a flocculating well is provided with two concentric drive cages: an outer drive cage that drives flocculation blades in rotation, and an inner drive cage that drives sludge collection arms across the base of the clarifier. Each drive cage is connected to a respective annular output gear, and each output gear is driven by a respective drive gear. The output gears are stacked one above the other, and each of the drive gears is connected to a respective speed reduction unit situated above the upper of the two output gears. The drive gear for the lower output gear is connected to the respective speed reduction unit by a drive shaft which passes through the upper output gear. Each of the speed reduction units is driven by a respective motor.
