Apparatus for separating off suspended matter from water

摘要

Apparatus for separating off suspended matter from water, such as surface water, industrial wastewater (effluent), biologically clarified wastewater and landfill leachate, having a tubular flocculation section, a plant section having the following features is connected downstream: a filter (F) is charged with granular material and arranged above the sedimentation part (S) of the plant and the flow passes through from bottom to top; a clean water container (R) containing filtered water is arranged above the filter; a float (K), in a position raised due to buoyancy, seals a connection orifice having an enlarged cross-section between filter and clean water container, a bypass (B) which, when the connection orifice is closed, conducts the clean water past the float into the clean water container; an outlet tube provided at the bottom of a sedimentation vessel having a shut-off apparatus (A) on the bottom is directed in the opposite direction to gravity to such an extent that when the shut-off apparatus is opened, at least a volume of fluid remains in the sedimentation vessel as a mixture of water and granular filter material. <IMAGE>
