VortSentry® HS
Hydrodynamic separator that uses a helical flow pattern that enhances containment of pollutants and provides effective removal of settleable solids and floating contaminants from urban runoff
The VortSentry® HS is a hydrodynamic separator with a small footprint that makes it an effective treatment option for projects where space is at a premium. It uses a helical flow pattern that enhances containment of pollutants and provides effective removal of settleable solids and floating contaminants from urban runoff.
The VortSentry® HS accepts a wide range of pipe sizes to treat and convey a wide range of flows. The unique internal bypass weir allows flows exceeding the treatment capacity to be diverted within the unit eliminating the need for an external bypass structure.
The system is housed inside a concrete manhole structure for easy installation and unobstructed maintenance access. In addition to standalone applications, the VortSentry® HS is an ideal pre-treatment device.

How the VortSentry® HS Treats Stormwater
Stormwater enters the VortSentry® HS through an inlet pipe or grate inlet
Low, frequently occurring storm flows are directed to the treatment chamber where a tangentially oriented downward pipe induces a swirling motion in the treatment chamber that promotes the separation of suspended solids. Oil and floating debris are also captured.
Moderate storm flows are directed into the treatment chamber through a secondary inlet, which captures floating litter and debris. The secondary inlet provides for treatment of higher flows without significantly increasing the velocity or turbulence in the treatment chamber
Flow exits the treatment chamber through the outlet flow control, which manages the amount of flow that is treated and helps maintain the helical flow patterns developed within the treatment chamber
Flows exceeding the system’s rated treatment flow are diverted away from the treatment chamber by the flow partition
Treated stormwater exits the VortSentry® HS via the outlet pipe
