Hydrodynamic separators are widely used in urban areas for removal of suspended sediments
and floatables from stormwater due to limited land availability for the installation of above
ground stormwater best management practices (BMPs). Hydrodynamic separators are often sized
based on some relatively frequent storm events. However, during less frequent storm events,
device design treatment rates are exceeded and previously captured sediments can be washed out
of the device.
