The Dual Vortex Separator
The Dual Vortex Separator (DVS) offers an innovative and economic alternative for BMP implementation in new and retrofit applications where space is limited and effective stormwater treatment is required.
The DVS is available in a range of sizes and is constructed as a precast concrete manhole or small vault structure with durable stainless steel internal components mounted inside. The system is typically delivered as a complete unit for installation by the contractor. Access to the installed system is allowed through ductile iron casting or hatch covers. The number of access points provided is dependent on the size and configuration of the system.
The Dual Vortex Separator is sized to meet site-specific requirements for treatment efficiency. Model selection is typically based on a mean particle size and target removal percentage as prescribed by the jurisdictional agency. Local rainfall data may also be used to support model selection. DVS units may be configured online or offline depending on agency requirements or the hydraulic capacity of the system.
