Echelon Blade Sloping Floor Clarifiers
A peripherally driven rotating half bridge with a robust scraper mechanism, the blades of which are arranged in a radial formation, to convey the sludge over the floor into a central well. A sludge draw-off pipe extends from the central well under the tank to an external chamber and the flow, which is under hydrostatic head, is controlled by a sluice valve. For final settling tank applications a adjustable bell-mouth is incorporated to regulate the rate of sludge removal.

A peripherally driven rotating half bridge with a robust scraper mechanism, whose blades are vee-shaped and supplied with adjustable flow uptake tubes, to lift the sludge under hydrostatic head to a sight box and transfer by syphon t o a sludge outlet drum for return into the system.
