HydroChain Stormwater Vortex Filter and Filter Cartridges by Shawcor

TWO-STAGE TECHNOLOGY TREATS ANY VOLUME OF STORMWATER

The HydroChain Vortex Filter and HydroChain Filter Cartridges combine sedimentation and an upflow filter process to remove liquid-bound and sediment-bound nutrients and metals, hydrocarbons, heavy metals and solids from stormwater. Both when installed as a unit (Vortex Filter) and installed separately (Filter Cartridges), a variety of filter options are available to fit a range of sites and stormwater volumes, including high-traffic areas and rooftops. The filters incorporate a variety of media to remove pollutants:

  • Active coal for adsorption of hydrocarbons and herbicides

  • Calcium carbonate for precipitation of dissolved phosphorous)

  • Synthetic zeolite for ion exchange of heavy metals

BACKED BY DECADES OF SUCCESSFUL INSTALLATIONS

  • 20+ years of stormwater treatment technology

  • Site-specific product design by in-house engineers

  • Stringent quality control of manufacturing

  • Comprehensive installation instructions

BENEFITS OF HYDROCHAIN VORTEX FILTER BY SHAWCOR

  • Installed in manholes, tanks or vaults that are designed to withstand H-25/HS-25 axle loads

  • Sedimentation + filtering = high removal performance

  • Simple Maintenance, just check the sludge level and flush the filter

  • Remove solids as needed and replace filter cartridges at an average of every 3-5 years

HOW THE VORTEX FILTER WORKS

  1. The stormwater feeds into the lower end of the filter housing, or the bottom of the manhole or tank. The angled inlet pipe generates a radial flow pattern.

  2. The hydrodynamic separator shifts turbulent stormwater into a radial laminar flow, which generates particle sedimentation.

  3. The larger particles settle at the bottom of the housing, manhole or tank. Suspended and settled solids are periodically cleaned out.

  4. In the central section of the unit, HydroChain Filter Cartridges filter out fine particles in an upward flow process. The majority of dissolved pollutants are precipitated and adsorbed.

  5. The Filter Cartridges can be flushed from street level and, when needed, are easily exchanged. The cartridges are easily removed (with lifting eyes) through the access opening.

  6. The clean water (above the filter elements) passes through an oil separator and flows through the outlet pipe into the groundwater or surface water.

NOTE: This shows the HCVF-5 model in a concrete manhole. The Vortex Filter is also available in a fiberglass manhole.

PROTECTING THE ENVIRONMENT

Stormwater runoff is a significant cause of water pollution. Engineered to meet the most stringent North American and global standards, this separator removes contaminants and produces water clean enough to re-enter surface water, waterways and groundwater infiltration systems. The following certifications and approvals are in process:

  • NJ Corporation for Advanced Technology (NJCAT)

  • NJ Department of Environmental Protection (NJDEP)

  • WA Department of Ecology (WADOE)

FLEXIBLE DESIGN FOR STORMWATER SYSTEMS OF ANY SCOPE

The Vortex Filter can be installed in a concrete or fiberglass manway. Multiple Vortex Filter units can be installed in a series as part of a large stormwater management system. Any number of Filter Cartridges can be installed in a fiberglass tank or concrete vault. The Filter Cartridges are a component of the HydroChain Complete, which also includes the HydroChain Prime Separator and a HydroChain FRP Tank.
