With increasingly stringent stormwater management regulations, finding a stormwater treatment
solution that is effective and efficient is
more challenging than ever.
Imbrium introduces the Jellyfish filter, an
engineered stormwater treatment technology
featuring pretreatment and membrane filtration in a compact system. The Jellyfish filter
removes a high level and a wide variety of
stormwater pollutants such as fine particulates,
oil, trash and debris, metals, and nutrients.
Treatment begins as stormwater enters the
Jellyfish through the inlet pipe, builds driving
head, and traps floating pollutants behind
the maintenance access wall. Water is pushed
down to the treatment chamber where a separation skirt around the cartridges traps oil, trash
and debris outside the filtration zone and
allows sand size particles to settle below
the cartridges in the sump. Water is forced
up from the treatment chamber, through membrane
filtration, and into the backwash pool. Once
the water has filled the backwash pool, water
overflows the weir and exits via the outlet
pipe.
The high performance membrane filtration provided by the Jellyfish filter's pleated tentacles
ensures long-lasting treatment and provides a 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.
As each storm subsides, the treated water
caught in the backwash pool flows back into
the treatment chamber through the membrane cartridges. This passive backwash extends
cartridge life and keeps them clear for future events. The draindown cartridge located outside
the backwash pool enables water levels to
balance.
The Jellyfish filter can be used in a number
of applications including:
Commercial and residential development, infill and redevelopment, and stormwater quality retrofit projects
Highways, airports, seaports, and military
installations
Pretreatment for Low Impact Development, infiltration
and rainwater harvesting and reuse systems
The Jellyfish filter is available in standard
manhole, catch basin and vault configurations,
as well as custom engineered configurations.
Maintenance of the Jellyfish filter 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. Typically replacement is anticipated
every 2-5 years.
Third party field testing for the Jellyfish
filter has been conducted following the TARP
Tier II protocol. The Jellyfish Filter has
achieved numerous agency approvals including
New Jersey Department of Environmental Protection final certification and Washington State Department
of Ecology conditional use level designation.
