The BIRCOhydroshark is a stormwater treatment system based on the hydrodynamic separator principle

1. The incoming stormwater is deflected into a radial flow pattern, a swirl separation technology.
2. Solids settle down into the sludge chamber, floatables are retained at the 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. Discharge of the treated water into the stormwater drain, infiltration trench or infiltration system.
