Device | Land use | Downstream BMP (type) | Mechanism enhancement | Sizing calculations | Inlets | Outlets | Openings | Flow diversion structures |
---|---|---|---|---|---|---|---|---|
Vortechs TM by Contech | Ultra-high density, Industrial, Commercial, "Hotspots" such as gas stations or high vehicular traffic areas1, 2 | Filtration, Detention/Infiltration, Rainwater Harvesting3 | Yes | Each system custom sized for site one of two ways: to provide a specific removal efficiency of a predefined particle size distribution, or by the Rational Rainfall Method. In most cases, pollutant removal goals can be met with a smaller system configured with an external bypass4, 5 | Perpendicular to vault to be tangential to grit chamber to induce swirling flow pattern6 | Orientation determined for each system 7 | Low flow control orifice sized to submerge inlet pipe when operating at 20%, High flow control weir sized to pass peak system capacity minus peak orifice flow7 | Baffle wall, circular grit chamber, flow control chamber, oil chamber8 |
Continuous Deflective Separation (CDS) R by Contech | Ultra-high density, Industrial, Commercial, "Hotspots" such as gas stations or high vehicular traffic areas8, 9 | Filtration, Infiltration, Detention10 | Yes | Three primary methods of sizing system: the Water Quality Flow Rate Method to provide a specific removal efficiency of a predefined particle size distribution, the Rational Rainfall Method, or the Probabilistic Method when a specific removal efficiency of net annual sediment load is required11, 12 | Grate inlet at street level and pipe inlet (may have multiple), inlet throat area sized to pass flow at surface elevation equal to crest of diversion weir, can be widened to increase capacity13 | Diversion weir length and height dimensions determine hydraulic capacity of system13 | Diversion chamber, diversion weir, separation chamber, separation screen, oil baffle13 | |
Downstream Defender TM H.I.L. Technology | Ultra-high density, Industrial, Commercial, "Hotspots" such as gas stations or high vehicular traffic areas15, 16 | Filtration, Infiltration, Detention, Wetland17 | Yes | Q = ciA (runoff coeff. * intensity * area), then see (NJCAT) or refer to sizing calculator from manufacturer (does not require registration) or updated design tool (requires registration) | Tangential to chamber18 | Sloping base joined to a benching skirt at a 30-degree angle, dip plate19 | ||
First Defense R by Hydro International | Ultra-high density, Industrial, Commercial, "Hotspots" such as gas stations or high vehicular traffic areas19, 20 | Filtration, Infiltration, Detention21 | Yes | Q = ciA (runoff coeff. * intensity * area), then see Table 1 (NJCAT) or refer to updated design tool from manufacturer (requires registration) | Grate inlet at street level and pipe inlet (may have multiple), max pipe diameter = 18-48 in22 | Max pipe diameter = 18-48 in, Min dist from outlet invert to top of rim = 2-3.5 in to 3-6 in depending first on model then on pipe diameter | Built-in bypass, inlet chute22 | |
Stormceptor R by Imbrium or Rinker Materials | Ultra-high density, Industrial, Commercial, "Hotspots" such as gas stations or high vehicular traffic areas23, 24 | Filtration and Detention/Retention systems25 | Yes | PCSWMM for Stormceptor available from manufacturer for optimal design and sizing purposes (requires registration) | Varies by model | Varies by model | Varies by model | Insert slows water and directs it to lower chamber, non-turbulent treatment chamber with bypass insert25 |
Barracuda by BaySaver | Ultra-high density, Industrial, Commercial, "Hotspots" such as gas stations or high vehicular traffic areas26, 27 | Filtration, Infiltration, Detention28 | No | Volume based, treatment chamber capacity ranges from 212 gallons to 7496 gallons29 | 12 in diameter, variable inlet/outlet angle configurations30, 31 | 12 in diameter, variable inlet/outlet angle configurations32, 33 | Weir prevents inflow from bypassing vortex separator, “teeth” reduce turbulence in sump area, inline may offer internal bypass34, 35 | |
Dual Vortex Separator by OldCastle | Infiltration, Detention, and Retention systems36 | Yes | See sizing and selection tool (does not require registration) | Fits 1-3 inlets, see sizing and selection tool for max pipe sizes (does not require registration) | Incoming flow directed into parallel vortex tubes, isolated storage area with baffles36 | |||
SciClone TM by BioClean | Filtration, Infiltration, Detention37 | Yes | Single outlet | Single outlet | Flow splitter, sump chamber, outlet weir38 |
