2H - Model SK - Sedimentation Tank
The SK tank series offers a range of compact, ready-to-connect units for separating solids from liquids. The sedimentation process in these units is based on the proven counter-flow principle. They are available in different sizes with settling areas of 2 - 72 m2 and flow rates of 2 - 70 m3/h for usual sedimentation tasks. 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.
Features of our 2H SK series
- Low-cost, round design with circular frame support
- Optimized flow dynamics
- Large, efficient sedimentation area by the 2HTUBEdek® units
- Very good sludge thickening in 60° conical hopper
- Rapid, easy installation
- Easily relocated to a new site
Round, cost-saving, with favourable flow dynamics
SKR tank units add the advantages of lamella clarifiers to those of round settling tanks. This efficient design is achieved with 2H TUBEdek® lamella separators, which can be cut to the round shape of the tank.
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.
The key component is found inside the tank: 2H TUBEdek lamellas. Numerous, equidistant sedimentation planes of the lamella clarifier ensure a reliable separation process, with a high hydraulic capacity.
Additionally V-shaped channels support the sludge discharge. 2H TUBEdek lamella clarifiers have proven themselves repeatedly in the field, regardless whether utilised as tank components or in large-scale systems.
