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 systems 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
|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 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
- 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 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 BMPs.
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.
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.
Treating Stormwater on Industrial Sites with Hydrodynamic Separation
Our stormwater treatment systems can be utilized on industrial sites and help bring sites into compliance with industrial National Pollutant Discharge Elimination System (NPDES) stormwater permits. We have over fifteen years of experience in the stormwater treatment market, and can provide reliable, flexible and cost-effective solutions to assist in meeting environmental permit requirements. Our hydrodynamic separation systems target sediment, trash and debris, and provide spill capture and containment for low density, non-soluble liquids like motor oil. These systems are typically specified as pretreatment upstream of stormwater filtration, infiltration or detention systems.
Keeping LID and GI sites free from fine sediments, oils, trash, and debris while functioning as designed can be time consuming and costly. The practice of combining LID with treatment systems like the Jellyfish Filter or CDS is becoming more common. Doing so increases water quality, provides a single point of maintenance, promotes proper system functionality, and increases the aesthetic appeal by removing unsightly trash and debris.
