The sedimentation plant unerringly removes the filterable substances (TSS) from the stormwater runoff. In this way, it protects water bodies and infiltration systems.

First, the water is introduced tangentially into the sedimentation plant in the middle of the system. Sedimentation of solids now takes place through the so-called teacup effect. The solids sink into the sludge trap at the bottom, which is hydraulically separated from the treatment chamber by a grate and flow breaker so that remobilization of settled particles does not occur during heavy rainfall.

In the outer ring of the sedimentation plant, the water flows evenly upwards. A weir ensures that there are no short-circuit flows in the plant and that the flow is as homogeneous as possible. The water then flows through the weir into the drain. Light substances such as oils or pollen are effectively retained, as they cannot pass under the separator wall. The sedimentation system has no height offset between inlet and outlet. The system cannot block. The system can be used on all surfaces, from roofs to traffic areas and industrial sites. The cleaning capacity is designed in such a way that the requirements of DWA M 153 and A 102 are reliably met.

Decentralized sedimentation plants are becoming increasingly important in the context of precipitation water treatment.
 

1. The water flows in tangentially in the center of the hydrodynamic separator.
2. Solids settle to the bottom, floating solids remain on the water surface.
3. Solids are collected in the sludge trap, which is hydraulically separated from the treatment chamber by flow breakers and a grate, so that remobilization does not occur.
4. The water rises evenly on the side walls.
5. The purified water is collected in an annular space by a weir and then transported to the outlet.
6. Outlet.
