Gravity Sedimentation: The Core Principle
Superthickener operation relies on the simple yet effective principle of gravity sedimentation. The wastewater is fed into the center of the large, circular tank. As the water flows radially outwards, the heavier solids settle to the bottom, forming a concentrated sludge layer. The clarified water overflows from the periphery of the tank, while the thickened sludge is removed at the bottom.
