Jellyfish® Filter


Setting New Standards in Stormwater Filtration

The Jellyfish Filter is an engineered Stormwater quality treatment technology featuring pretreatment and membrane filtration in a compact stand-alone treatment system, which removes a high level and wide variety of Stormwater pollutants.

What is the Jellyfish Filter?

The Jellyfish Filter is an engineered Stormwater quality treatment technology featuring pretreatment and membrane filtration at high flow rates, while delivering high level performance and treatment longevity.  Jellyfish units are compact stand-alone treatment systems that are available in multiple standard configurations as well as project specific custom configurations.



  • Maintenance access wall and separation skirt trap floatables, trash, oil, and debris, prior to stormwater entering the filtration zone.

  • Sand sized and larger particles settle below the filter zone in the collection sump.


  • Pleated membrane, high treatment surface area, tentacles provide effective removal of fine sand and silt sized particles.

  • Removes high percentages of particulate bound pollutants; including nutrients, metals, and hydrocarbons.

  • 80 gpm (5L/s) treatment flow rate per cartridge with 18” upstream driving head.

  • High surface area membranes extend performance and treatment longevity.

Extended Filter Life

  • Post peak storm event, filtered water back washes membrane tentacles.

  • Continuous gravity removal of sediment from tentacles.

  • Long maintenance frequency periods.

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.
