➤➤➤ Features

ROTAMAT® Screw Thickener for big wastewater treatment plants  
A preceding flocculation reactor with stirrer ensures efficient sludge treatment in the screw thickener. The screw thickener consists of a cylindrical wedge section basket which retains the solids contained within the fed sludge. A screw, slowly rotating with variable speed, conveys the solids 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. A rotating spray bar cleans the wedge wire periodically from the outside during screw operation.
