The Stormwater Management StormFilter improves the quality of stormwater runoff before it enters receiving waterways using its customizable filter media, which removes non-point source pollutants.
The StormFilter is typically comprised of a vault or manhole structure that houses rechargeable, media-filled filter cartridges to absorb and retain the most challenging pollutants from stormwater runoff including total suspended solids, hydrocarbons, nutrients, soluble heavy metals, and other common pollutants.
Stormwater entering the system is siphoned through these media filled cartridges providing efficient, effective stormwater treatment.
Once filtered through the media, the treated stormwater is discharged through an outlet pipe to a storm sewer system or receiving water. The StormFilter has a flow control positioned at the base of the cartridge, which allows the contact time with the media to be adjusted. Longer contact times produce higher removal for contaminants including finer particles. The StormFilter also has a passive self-cleaning function that extends the life of the media. The self-cleaning function is activated when the siphon is broken at the end of the storm event.
The StormFilter is available in multiple cartridge heights to meet site-specific hydraulic needs and is available in different configurations and comes with prolonged maintenance periods to ensure long-term performance and reduce operating costs.
For more than two decades, StormFilter has helped clients meet their regulatory needs, and through product enhancements the design continues to be refined for ease of use.
