Rotary Screw Thickener S-DRUM

Manufacturer: Huber Technologies

HUBER Screw Thickener for big wastewater treatment plants
 Sturdy, highly efficient and flexibly applicable unit
A preceding flocculation reactor with stirrer ensures a sludge flock quality that allows thickening of the stabilized flocks. The screw thickener is comprised of an inclined wedge section basket. A screw, slowly rotating with variable speed, conveys the sludge gently upward through the inclined basket. Water drains through the basket.
The degree of thickening is adjustable by means of a height adjustable weir plate in the sludge discharge and the variable screw speed. Wedge wire cleaning is performed during screw operation by means of an automatic washing system.

 Sludge volume reduction to up to 90 %
 Sturdy design for high solids loads and coarse material containing sludge
 Maximum system availability due to the virtually wear-resistant and clog-free stainless steel wedge section basket
 No need for lubrication
 High operational reliability due to the defined discharge velocity
 Completely encapsulated, odor-free plant
 Low noise < 68 dB(A)
