Jellyfish Filter Configurations

The Jellyfish Filter can be can be configured in a variety of systems; manhole, catch basin, vault, or custom configuration.  Typically, 18 inches (457 mm) of driving head is designed into the system. For low drop sites, the designed driving head can be less.

Jellyfish Filter Applications

• Commercial and residential development, infill and redevelopment and stormwater quality retrofit applications
• Highways, airports, seaports and military installations
• Pretreatment for Low Impact Development, infiltration, and rainwater harvesting and reuse systems

Jellyfish Filter Maintenance

• Jellyfish Filter cartridges are lightweight, easy to use, and reusable
• Maintenance of the filter cartridges is performed by removing, rinsing and reusing the cartridge tentacles.
• Vacuum extraction of captured pollutants in the sump is recommended at the same time.
• Full cartridge replacement intervals differ by site due to varying pollutant loading and type, and maintenance frequency.  Replacement is anticipated every 2-5 years.
• Contech has created a network of Certified Maintenance Providers to provide maintenance on stormwater BMP’s.

The Jellyfish Filter is a stormwater quality treatment technology featuring high surface area, high flow rate membrane filtration, at low driving head. By incorporating pretreatment with light-weight membrane filtration, the Jellyfish Filter removes a high level and a wide variety of stormwater pollutants. The high surface area membrane cartridges, combined with up-flow hydraulics, frequent passive backwashing, and rinseable/reusable cartridges ensures long-lasting performance.

How the Jellyfish Filter Treats Stormwater

• Stormwater enters the Jellyfish through the inlet pipe or inlet grate, builds driving head, and traps floating pollutants behind the maintenance access wall and below the cartridge deck.
• Water is conveyed below the cartridge deck where a separation skirt around the cartridges isolates oil, trash and debris outside the filtration zone, allowing sand-sized particles to settle in the sump.
• Water is directed to the filtration zone and up through the top of the cartridge into the backwash pool. Once the water has filled the backwash pool, clean water overflows the weir where it exits via the outlet pipe.
• The membrane filters provide a very large surface area to effectively remove fine sand and silt-sized particles, and a high percentage of particulate-bound pollutants such as nitrogen, phosphorus, metals, and hydrocarbons while ensuring long-lasting treatment.
• As influent flow subsides, the filtered water in the backwash pool flows back through the hi-flo membrane cartridges into the lower chamber.  This passive backwash extends cartridge life, keeping the membrane clean for future events.
• The draindown cartridge(s) located outside the backwash pool enables water levels to balance.
