Overview


Vortechs® Stormwater Treatment

Vortechs is a hydrodynamic separator that combines swirl concentration and flow controls into a shallow treatment unit that traps and retains trash, debris, sediment, and hydrocarbons from stormwater runoff. Vortechs removes sediment down to 50 microns and is the ideal solution for projects that require a shallow treatment device due to groundwater, utility or bedrock constraints.

Stormwater Treatment For Shallow Applications

Vortechs is a below-ground, engineered stormwater treatment device that combines swirl concentration and flow controls into a single treatment unit. Vortechs is ideal for capturing and retaining trash, debris, sediment, and hydrocarbons from stormwater runoff. The Vortechs system’s large swirl concentrator and flow controls work together to create a low energy environment, ideal for capturing and retaining particles down to 50 microns.

How Vortechs Treats Stormwater
  • Untreated stormwater enters the Vortechs swirl chamber through an inlet pipe.
  • The swirling motion of the water within the chamber promotes gravitational separation of solids which settle on the chamber floor.
  • Stormwater exits the swirl chamber, where a baffle wall traps floatables and hydrocarbons.
  • Stormwater flows under the baffle wall into the flow control chamber which contains separate flow controls for peaks and low-intensity flows that are designed specific to project requirements.
  • Treated stormwater flows to the outlet chamber and exits via the outlet pipe.

Vortechs Approvals

Vortechs has been tested and verified by some of the most stringent stormwater technology evaluation organizations in North America, including:

  • Washington State Department of Ecology
Vortechs Applications
  • Stormwater quality control - trash, debris, sediment, and hydrocarbon removal
  • Inlet and outlet protection
  • Pretreatment for filtration, detention/infiltration, bioretention, rainwater harvesting, and Low Impact Development designs.
Vortechs Maintenance
  • Vortechs provides unobstructed access to stored pollutants, making it easy to maintain.
  • Maintaining a Vortechs is a simple process that can be easily accomplished using a vacuum truck, with no requirement to enter the unit.
  • Contech has created a network of Certified Maintenance Providers to provide maintenance on stormwater BMP’s.

Applications
Pretreatment for Rainwater Harvesting

Our hydrodynamic separation products are ideal solutions for preatreatment to rainwater harvesting. Not only do they improve the overall water quality, they also provide protect the pumps and controls from being overburdened with material that could clog and damage the mechanical system.

Pretreatment to Storage

Our hydrodynamic separators are frequently installed upstream of detention and infiltration systems as pretreatment devices. By capturing the majority of sediment, hydrocarbons and trash and debris upstream of the storage system, maintenance becomes much easier as material is congregated into a smaller device with clear access for cleanout. Additionally, by utilizing pretreatment upstream of infiltration systems, sediment that would have clogged the stone voids in the storage envelope surrounding the storage chamber can be captured before entering the storage system thus extending the longevity of the entire system.

Hydrodynamic Separation for Water Quality

Our hydrodynamic separation products (including the CDS, Vortechs, and VortSentry HS) are reliable, easy to install, and offer high-performance, proven, stormwater pollutant removal. The systems are widely accepted for effective solids removal and can be designed to achieve your site treatment goals - including TMDL requirements for TSS and trash.

Hydrodynamic Separators for Inlet and Outlet Pollution Control

Keep trash and debris out of your lakes, streams and oceans by installing one of our hydrodynamic separators at the inlet or outlet of your drainage system. Our systems - which include the CDS, Vortechs, and VortSentry HS - are most effective on sediments, trash and debris, and oil and grease.
