Vortechs® Stormwater Treatment

Stormwater Treatment For Shallow Applications

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.

Vortechs Overview

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 Features and Benefits

Features

Benefits

1. Large swirl chamber 1. Fine particle removal down to 50 microns
2. Shallow profile – Typical depth below pipe invert is only 3 feet.  2. Easy and cost-effective installation, especially on sites with high groundwater, bedrock or utility conflicts
3. Unobstructed access to stored pollutants 3. Easy maintenance
4. Numerous regulatory approvals 4. Proven performance


Vortechs Configurations

  • Large hydraulic capacities often allow peak flows to be bypassed internally
  • Cast in place options available for projects requiring treatment

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
  • New Jersey Department of Environmental Protection

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.

Hydrodynamic Separators for Inlet and Outlet Pollution Control

Vortech Outlet ProtectionKeep 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.

Hydrodynamic Separation for Water Quality

CDS Water QualityOur 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.

Treating Stormwater on Industrial Sites with Hydrodynamic Separation

Stormwater Treatment IndustrialOur stormwater treatment systems can be utilized on industrial sites and are able to comply with the National Pollutant Discharge Elimination System (NPDES) industrial stormwater permits. We have over a decade of experience in the industrial stormwater treatment market, and can provide reliable, flexible and cost-effective solutions to meet environmental permit requirements. Our hydrodynamic separation systems target solids and trash and debris, and can be an effective pretreatment system prior to a filtration system.

Pretreating with HDS Systems

CDS PretreatmentOur hydrodynamic separation systems - CDS, Vortechs and VortSentry HS - installed as pretreatment can ultimately improve runoff reduction over time by reducing loading to bioretention and extend maintenance intervals by removing sediment before bioretention.
