Removing Pollutants at High Levels
The Vortex Filter removes liquid-bound and sediment-bound nutrients and metals, hydrocarbons, heavy metals and solids by combining sedimentation and an upflow filter process. The filters remove pollutants from stormwater using active coal (for absorption of hydrocarbons and herbicides), calcium carbonate (for precipitation of dissolved phosphorus), and synthetic zeolite (for ion exchange of heavy metals). Whether installed in manholes or vaults, the filters are configured for specific site requirements.

Success Story
Philadelphia, Pennsylvania
As part of an urban redevelopment project in Pennsylvania, two HydroChain products create a stormwater management system capable of more than 460,000 cubic feet of runoff storage. The system serves new industrial warehouses that replaced the site’s former Philadelphia Coke Plant. Key to obtaining this project was the ready availability of the products and the cost savings realized over another manufacturer’s products that were originally specified.
More than 10,000 chambers provide storage and infiltration. The HydroChain fiberglass-reinforced plastic chambers provide superior strength and long-term reliability. The 92 filter cartridges installed in a concrete vault provide water quality treatment with high-performance pollutant removal, including more than 90% removal of trash and debris, and more than 80% removal of TSS, petroleum hydrocarbons and heavy metals.
