Hydrodynamic Separator (HDS)

HDS systems are designed to separate floatable material (trash, debris, and oil) and settleable particles, like heavy sediment, from stormwater.

These systems are not effective for the removal of very fine solids or dissolved pollutants (see Filter products). There are many Manufactured Treatments Devices, such as CDS, Stormceptor, Cascade, Vortechs, Downstream Defender, DVS, and NSBB on the market and understanding the inspection and maintenance requirement for each is a vital part of stormwater management.
