The sedimentation tank units come in 13 different standard types and are adaptable to specific project requirements. Tank size, projected sedimentation area, the appropriate 2H TUBEdek type and the flange size of inlet, outlet and sludge drain connections can all be selected accordingly.
The SKR is divided into four areas:
• Inlet area
• Thickening and sludge accumulation zone
• Separation zone with 2H TUBEdek lamellas
• Clear water zone with launders
The influent enters the SKR from two opposite sides. In the influent sections the incoming flow is slowed down, descends and then rises up through the 2H TUBEdek lamellas. The solids settle on the lamella planes before sliding down to the hopper. In the thickening and accumulation zone, settled solids thicken further. The clear phase rises and is collected in the launders.
Separated sludge has to be extracted from the thickening zone’s sump in regular intervals.
Rectangular SK-tank unit
In addition to our standardised SKR design, we also supply special solutions consisting of square-design tank units. Special transport requirements (e.g. in containers) or space requirements at the installation site can be met by this design. This tank type, too, achieves an optimal water distribution by carefully chosen design details.
SK tanks can be installed easily and quickly. The innovative circular design (SKR) does not only save costs but also calms the influent stream, achieves a uniform flow distribution in the lamellas and facilitates the sludge concentration in the hopper.
