  • X2 Solutions | Thickener Bridge with central drive

    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

  • Gravity Sludge Thickener Bridge Mounted

    Thickeners are used in water and wastewater applications to take solids from other liquid solids separation processes and thicken the solids prior to further dewatering and/or digestion. The drive is mounted on the walkway or bridge. The rotating portion of the drive turns a structural torque tube or shaft, which in turn rotates the solids removal mechanism.
