Advantages of a vertically and radially floating baffle:
- Low-maintenance
- Free of foreign energy
- Complete retention of floating matter in the event of fluctuating water levels
- No restrictions for the overflow height
- Cheaper compared to vertically floating baffle due to shorter construction height
- Simple, functionally safe design
- GRP material with superior floating properties
Vertical and radial floating baffles are preferably used for the retention of floating material at spillways in combined sewer systems. Prevalent applications include emergency overflows on storage sewers, storm-water retention basins (SRBs), storm-water overflow basins (SOBs) and storm-water clarification basins (SCBs) and on clarification overflows on SCBs.
It was specially developed for the retention of floating material at spillways with a large overflow height and a large distance between the top of the sill and the invert in front of the sill. In this particular constellation, this form of floating baffle can initially abut the sill in exactly the same way as the radially floating baffle. As the water level rises, the baffle moves away radially from the spillway and can then rise vertically to any height as the water level rises.
The vertically and radially floating baffle is connected to the structure at both ends by a guide tube. This guide tube is bent in such a way that the baffle can float along the previously described path. The use of seals prevents contamination of the guides. Vertical and radial floating baffles are made of GRP, which has excellent floating properties.

Consisting of
- Baffle body designed as a floating body with side lip seals. The geometry of the floating body is designed in such a way that enough buoyancy is generated around the entire construction to carry the whole baffle on a rising water level.
Length: according to clear crest length
Height: according to the regulations of the DWA, designed for an overflow of ______ mm
Material: Stainless steel - Stainless steel guide rails to hold the vertical and radial sliding bearing of the baffle body, including stainless steel screws, dowels and required mounting accessories.
Height: ______ mm
Quantity: 2 pieces
The guide rails are dowelled to the crest and bent in such a way that the baffle in its vertical position has the right distance to the overflow crest according to the above overflow height and DWA worksheet. - Stainless steel ceiling bearing to accommodate the bearing points of the guide tubes, including stainless steel screws, dowels and required mounting accessories.
Quantity: 2 pieces
Functional requirement
In the rest position, the baffle must lean to the weir crest of the tank, so that with increasing water level no floating matter can get between the baffle and the overflow crest. With rising water level, the baffle must move radially from the overflow crest to avoid floating material from getting into the cross-section between baffle and overflow crest. If the water level is rising even more, the baffle will float vertically up to max. the ceiling of the retention tank, while at the same time releasing the maximum amount of relief water.
