Sedimentation Cone

Sedimentation Cone also known as Imhoff cone. Named after the German engineer Karl Imhoff, these graduated glass cones are used to measure the volume of settle able solids in a one liter volume of water or wastewater. sedim. Complies to DIN 12672. For determining the amount of sediment in sewage or industrial waste. Graduated up to a capacity mark at 1000ml. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation.

The settling velocity, defined as the residence time taken for the particles to settle in the tank, enables the calculation of tank volume. Precise design and operation of a sedimentation tank is of high importance in order to keep the amount of sediment entering the diversion system to a minimum threshold by maintaining the transport system and stream stability to remove the sediment diverted from the system. This is achieved by reducing stream velocity as low as possible for the longest period of time possible. This is feasible by widening the approach channel and lowering its floor to reduce flow velocity thus allowing sediment to settle out of suspension due to gravity. The settling behavior of heavier particulates is also affected by the turbulence.
