In 2010 & 2011 the Jellyfish Filter was TARP field tested over a duration of 25 storm events adhering to New Jersey Department of Environmental Protection (NJDEP) amended TARP field monitoring protocol. Additional field testing is ongoing on a JF4 (1200 mm diameter) unit providing treatment of a commercial site in Ispwich, Australia, which is a suburb of Brisbane. The monitored catchment’s total drainage area is 1,678 sq. meters, with approximately 550 sq. meters of roof area and 1,128 sq. meters of impervious driveway and parking lot.

Stormwater Australia has released a draft of its Stormwater Quality Improvement Device Evaluation Field Monitoring Protocol (SQIDEP), which this monitoring has been closing adhering too. Accordingly, Queensland University of Technology (QUT) undertook a comprehensive field based monitoring study to verify the performance of the Jellyfish Filter, sponsored by Humes Water Solutions, the licensee of Jellyfish Filter in Australia. The interim findings after 7 qualifying storm events has provided the following initial Jellyfish Filter performance assessment:

  • Median concentration reduction efficiencies:
    • TSS – 89%
    • TN – 55%
    • TP – 65%
  • Monitored stormwater quality in terms of TSS, TN and TP are well within the expected stormwater treatment quality for the Brisbane region.
  • Comparison of monitored rainfall events suggests that these are within the envelope of typical rainfall events for Brisbane.
  • Performance characteristics observed in this monitoring study are comparable with the performance reported in the previous Jellyfish Filter TARP study.
