The proven solution for float material retention
Baffle wall (APA-TW)
The proven solution for float material retention.
In In rainwater basins without a baffle, a thin top layer of water flows to the drain at a speed several times faster than the flow speed in the basin.
If a baffle is present, there is usually almost no current both at the surface and to a depth that corresponds approximately to the depth of immersion of the baffle. Therefore, the baffle should only reach as deep into the water as is absolutely necessary to prevent floating matter from entering the drain under the baffle.
In general, a depth of 20 cm is sufficient. The distance to the overflow edge should be at least 30 cm. The material thickness of the baffle should be 5 mm for the stainless steel version.
