Stormwater Vortex Separator

Stormwater Vortex Separator

Stormwater Vortex Separator

Currently involved in a project where we wish to separate out coarse particles of metal from stormwater runoff.  One proposal is to use a 'Hydrodynamic Vortex Separator'.  I appreciate the principle of this type of system, however, I have not had any experience with them.  Can anyone offer advice on their effectiveness and/or suitability, or direct me to a source of information that does.

RE: Stormwater Vortex Separator

EPA has developed "Technology Fact Sheets" for a number of wastewater, CSO, and stormwater technologies.  They are unbiased, don't constitute endorsement, but didn't involve lab testing either.  Go to:


and click on "hydrodynamics" under stormwater.

My view of these technologies is that they are fine for heavy particles that settle out, and for floatables (litter) - NOT for fines or phosphorous, typical municipal stormwater.  (So metals would be OK, if maintained.)  They also have applications for highways where hydrology and space constraints restrict conventional surface detention.

Try CDS Technologies.


Take care
