Storm runoff enters the VortSentry HS stormwater treatment system via an inlet pipe or grate inlet. The water is directed to the treatment chamber through the primary inlet. The downward pipe primary inlet set tangentially persuades a swirl flow path in the treatment chamber. This helical flow path promotes and enhances gravitational separation of trash, floatables and sediments settling on the chamber floor. The treated flow exits the treatment chamber by the outlet flow control. For peak flows, the VortSentry HS has an internal flow partition, where flows exceeding its rated treatment flow rate would flow into the secondary inlet and down to the treatment chamber.
VortSentry
The VortSentry HS is a compact, durable stormwater treatment system utilizing helical flow technology to promote and enhance separation of floatables and other contaminants from stormwater flows. The VortSentry HS system is capable of achieving an 80% annual solids load reduction.
The VortSentry HS comes available in 3 configurations. An inline, a grate inlet configuration which can be designed for retrofit installations (if applicable) and combination of grate and pipe inlet. It is also available in 36 inch (900-mm) to 96 inch (2400-mm) diameter manholes.
In cases of flows exceeding the treatment capacity, the internal flow partition allows for excess flow to be diverted and exit the system without the need for external bypass structures.
