The FloGard® Dual-Vortex Hydrodynamic Separator provides enhanced gravity separation of suspended stormwater pollutants in a compact configuration. Particle settling or floatation is accelerated by centripetal forces induced by the tangential flow pattern augmented by a highly circuitous flow path. The unit uses two independent cylindrical separators: Low flow is diverted by the inlet to the first separator, while moderate flow begins to overflow the first control weir and enter the second separator. Settled particles collect in the bottom storage area of the unit which is isolated from the fluid outlet, minimizing resuspension. Floating debris and oils are temporarily held at the top of each separator and deposited in the upper storage area by peak storm events. Once the unit treatment capacity is exceeded, excess flow breaches a second control weir at the inlet and passes through the bypass pipe without decreasing the treatment flow or re-entraining captured pollutants.

FloGard® Dual-Vortex Hydrodynamic Separators are designed to effect greater than 80% removal of TSS reflective of typical urban runoff. Units are sized to treat stormwater at the design removal efficiency in an equal or smaller footprint than equivalent competitor's products.

The FloGard® Dual-Vortex Hydrodynamic Separator is constructed of durable stainless steel and fiberglass components installed in a reinforced concrete structure. All internal parts are easy to install, and may be removed in the field through a 48" self-lifting access lid for easy, complete cleaning access.

Kristar's FloGard® Dual-Vortex Hydrodynamic Separator offers a new economical alternative structural BMP for use in developments where land area necessitates compact, effective treatment for removal of suspended pollutants from stormwater runoff.
