V2B1 General Information
When it comes to Stormwater Treatment,
don't fish in troubled waters!
Eighty percent of the pollution to North America’s fresh water resources can be attributed to storm water runoff. V2B1 is our answer to non-point source discharge pollutants. Sediments contaminated by hydrocarbons and their floating residuals flow freely from paved, impervious sites into storm water collection systems. Mitigated wetlands and storm water ponds are historically accepted as the method of controlling storm water quality. While ponds and wetlands are, on one hand, an effective treatment for non-point source discharges, they occupy valuable commercial property and create an open water liability (i.e. school applications). V2B1 has also been designed for gross particulate removal upstream of constructed ponds, therefore extending the frequency interval for required pond maintenance.
V2B1 makes optimum use
of two consecutive purification steps.
V2B1 consists of 2 circular precast structures: An upstream swirl-chamber/vortex separator (first structure) and a floatables collection chamber and outlet chamber (second structure). Swirl-chamber technology combined with vortex design principles, effectively treat the storm water by removing and retaining sediments and floatables from site runoff.
Dimensioning.
Industry standards consider the two month storm event to be a
rainfall with intensity, duration and frequency sufficient enough to create
run-off velocities that "flush" a site of non-point source pollutants.
Each system is custom designed by Environment 21 engineers using local
precipitation data to ensure optimum performance during the full range of storm
events. Sizing of the system also
depends upon recurrence interval and flow rate information provided for that
site’s storm drainage design. Please contact our design engineers for free
