Stormwater management filtration

The Stormwater Management StormFilter removes the most challenging target pollutants – including fine solids, soluble heavy metals, oil, and total nutrients – using a variety of sustainable media. For more two decades, StormFilter has helped clients meet their regulatory needs, and through product enhancements the design continues to be refined for ease of use.
Stormwater Management StormFilter

Here's why StormFilter is the best filter available:

Superior Hydraulics

  • External bypass – ensures easy access to a removal of trash and debris which could clog system over time and cause backwater
  • Three standard cartridge heights available – 27”, 18”’, and 12” – shrink system size, reducing install costs, and minimize head loss to fit within the hydraulic grade line.
  • Over 30 StormFilter configurations in use across the country

Reliable Longevity

  • One-of-a-kind self-cleaning hood – Prevents surface blinding, ensures use of all media, and prolongs cartridge life
  • Two-year maintenance cycles - Fewer maintenance events compared to similar products reduces costs over the lifetime of the system
  • 15-years of maintenance experience – Predictable long-term performance comes standard

Proven Performance

  • Only proven filter on the market - Performance verified by the WA DOE and NJ DEP
  • Achieve water quality goals with confidence – Easy approval speeds permitting
  • 8th Generation Product – Design refined and perfected over two decades of research and experience
  • Full-scale testing at more than 10 sites around the United States

Underground System Maximizes Profitability

  • Save land space, allow denser development and reduce sprawl
  • Add parking, increase building size, develop outparcels by eliminating above ground systems
  • Compact design also reduces construction and installation costs by limiting excavation

Filtration for Removing Pollutants Prior to Discharge

StormFilter Inlet ProtectionMedia filtration systems - like our StormFilter, Jellyfish Filter, and MFS systems are able to remove the most challenging pollutants from stormwater, including total phosphorus, soluble metals, oil, and very fine particles (down to 15 microns). Available in a variety of configurations (vault, manhole, catch basin, high flow and volume), these systems can be engineered to treat a wide range of flows within your drainage system and capture pollutants prior to discharge off-site.

Filtration Systems for Water Quality

Filter for Water QualityThe Stormwater Management StormFilter, Jellyfish Filter, and MFS systems provide the highest level of treatment and meet the most stringent regulatory requirements. These low maintenance systems combine pretreatment and filtration, and are able to target site-specific pollutants to meet your water quality goals. Our field-proven products have earned hundreds of standalone BMP approvals from regulatory agencies nationwide.

Filtration for Industrial Sites

StormFilter Inlet ProtectionUse the StormFilter, Jellyfish Filter, and MFS systems to target fine solids, dissolved metals and oil and grease from stormwater runoff at a variety of industrial sites. These systems can effectively remove zinc and airborne particulates from metal roofing, dissolved cooper and other metals leaching from condenser tubing, and paint from surface preparation and painting, to name just a few. We provide the reliability and flexibility you need to meet environmental permit requirements.

Filtration for LID Designs

A-2026 for SanitaryThe Stormwater Management StormFilter, Jellyfish Filter, and MFS systems can be easily configured as decentralized, small scale inlets, including catch basin, curb inlet and manhole systems to meet LID treatment requirements. The systems provide high removal efficiency for primary pollutants of concern.
