Ovivo® Bridge Supported Clarifier
Ovivo® bridge supported clarifier units have their sludge removal system hanging from a structural bridge spanning the tank. Wastewater enters through a side feed pipe into the center feedwell. The feedwell boosts flocculation of the suspended solids, which flow out into the clarifier to create a sludge blanket on the tank bottom. Rotating rake arms can be equipped with plow blades, spiral blades or suction ducts to remove the sludge, while a skimming device collects the scum at the surface.
