<strong>JellyFish®</strong> <strong>filter</strong><br />
The <strong>JellyFish®</strong> <strong>filter</strong> is a tertiary stormwater treatment system featuring membrane<br />
filtration to provide exceptional pollutant removal at high treatment flow rates with<br />
minimal head loss and low maintenance costs.<br />
<strong>JellyFish®</strong> <strong>filter</strong><br />
The <strong>JellyFish®</strong> <strong>filter</strong> uses gravity, flow rotation, and<br />
up-flow membrane filtration to provide tertiary<br />
treatment to stormwater in an underground structure.<br />
Using unique filtration cartridges, each <strong>JellyFish®</strong> <strong>filter</strong><br />
provides a large membrane surface area, resulting in high<br />
flow rates and pollutant removal capacity.<br />
The <strong>JellyFish®</strong> <strong>filter</strong> efficiently captures a high level of<br />
stormwater pollutants, including:<br />
• Total Suspended Solids (TSS), median removal<br />
efficiency of 89%, including particles down to<br />
two microns<br />
• Total Nitrogen (TN), median removal efficiency of 48%<br />
• Turbidity median removal efficiency of 85%<br />
• Total Phosphorous (TP), median removal efficiency<br />
of 67%<br />
• Total Copper (Cu), median removal efficiency of 61%<br />
• Total Zinc (Zn), median removal efficiency of 91%.<br />
Designed as a polishing device for constrained sites, the<br />
<strong>JellyFish®</strong> <strong>filter</strong> is available in a range of sizes to cater for<br />
both at-source and end-of-pipe solutions.<br />
• The system provides tertiary level performance with a<br />
small footprint<br />
The proven performance of the <strong>JellyFish®</strong> <strong>filter</strong> and<br />
high flow rate membranes enables water quality<br />
objectives to be met with a smaller footprint system<br />
than typical bioretention systems.<br />
• It has been independently researched and proven<br />
The <strong>JellyFish®</strong> <strong>filter</strong> has been independently researched<br />
under both laboratory and field conditions in the<br />
United States and Australia. In the United States, it has<br />
received verification under the stringent New Jersey<br />
Corporation for Advanced Technology (NJCAT) protocol.<br />
• It treats higher flow rates than most <strong>filter</strong>s<br />
Each <strong>filter</strong> cartridge has an effective <strong>filter</strong> area of<br />
35.4 m 2 designed to treat 5 litres per second (L/s)<br />
during operation.<br />
• Above-ground land use is maintained<br />
The system is assembled within a fully-trafficable,<br />
precast concrete structure for underground<br />
installations on constrained sites, allowing maximum<br />
use for above-ground activities.<br />
• Maintenance is easy<br />
The <strong>filter</strong> backwashes after peak flows so it can<br />
self-clean several times in each storm event. Manual<br />
backwash is recommended annually. When cartridge<br />
replacement is required (usually every three to five<br />
years), it is a safe and simple process.<br />

<strong>JellyFish®</strong> <strong>filter</strong> 1
System components<br />
The <strong>JellyFish®</strong> <strong>filter</strong> is comprised of several structural and<br />
functional components:<br />
• A cylindrical precast concrete structure which is<br />
available in a range of diameters and depths that<br />
serves as a vessel providing structural support<br />
for a 50 year design life and provides storage for<br />
accumulated <strong>filter</strong>ed pollutants.<br />
• A rigid high-strength fibreglass cartridge deck<br />
separates the vessel into a lower chamber and upper<br />
chamber. This houses the <strong>filter</strong> cartridges, provides<br />
a surface and flow path for treated water to the<br />
effluent pipe, and provides containment of oil and<br />
other hydrocarbons below the deck and also provides<br />
a platform for maintenance personnel to safely service<br />
the <strong>filter</strong> cartridges.<br />
• The lower chamber provides storage for pollutant<br />
separation and membrane filtration.<br />
• The upper chamber provides adequate clearance for<br />
inspection and maintenance.<br />
• A rigid high-strength fibreglass Maintenance Access<br />
Wall (MAW) attenuates influent water velocity and<br />
directs flow into the lower chamber through a large<br />
opening in the cartridge deck. In addition, it provides<br />
storage for floatable pollutants. It also serves as an<br />
inspection and maintenance access point.<br />
• <strong>JellyFish®</strong> membrane filtration cartridges are secured<br />
to the deck by the cartridge lids. Each <strong>filter</strong> cartridge<br />
consists of multiple membrane <strong>filter</strong> tentacles, which<br />
treat the stormwater by <strong>filter</strong>ing out fine suspended<br />
particulates (TSS) and particulate-bound pollutants on<br />
the membrane of each tentacle. Filtered water passes<br />
through the membranes, up the centre tube of each<br />
tentacle and exits through the top.<br />
• Filter cartridges are designated as either high-flow or<br />
draindown cartridges, depending on their location in<br />
the cartridge deck. High-flow cartridges placed within<br />
the backwash pool are automatically backwashed after<br />
each storm event.<br />
• Draindown cartridges located outside the backwash<br />
pool facilitate the draindown of the backwash<br />
pool. The design flow rate (2.5 L/s) of a draindown<br />
cartridge is controlled by the lid orifice. The lower<br />
design flow rate of the draindown cartridge ensures<br />
the membranes last for longer periods between<br />
scheduled maintenance.<br />
• Cartridge lids are fastened into the deck to securely<br />
anchor the <strong>filter</strong> cartridges. The lids are removable to<br />
allow <strong>manual</strong> rinsing and replacement of the <strong>filter</strong><br />
cartridges when required. Cartridge lids contain a<br />
flow control orifice that is specifically sized for use<br />
with high-flow and draindown cartridges. Blank lids<br />
have no orifice and are used to cover unoccupied deck<br />
apertures in systems that do not use the full rated flow<br />
capacity of the system.<br />
• A rigid fibreglass backwash pool weir extends<br />
150 mm above the cartridge deck and encloses the<br />
high-flow cartridges. During inflow, <strong>filter</strong>ed water<br />
leaving the high-flow cartridges forms a pool inside<br />
the weir. When the water level in the pool exceeds<br />
the weir height it overflows and spills to the cartridge<br />
deck where it then flows to the outlet pipe. As the<br />
inflow event subsides and pressure decreases, water<br />
in the backwash pool reverses flow direction and<br />
automatically backwashes the high-flow cartridges,<br />
cleaning the membrane surfaces. Water in the lower<br />
chamber (below deck) is displaced through the<br />
draindown cartridges.<br />
This self-cleaning mechanism may occur multiple<br />
times during a single storm event as rainfall/runoff<br />
intensities rise and fall, thereby significantly<br />
extending the service life of the cartridges and the<br />
maintenance interval.<br />
2 <strong>JellyFish®</strong> <strong>filter</strong>
• A separator skirt encloses the filtration cartridge<br />
and defines the filtration zone. The separator skirt<br />
extends the full length of the filtration tentacles and<br />
prevents contamination of the membranes with oil<br />
and floatable debris. The separator skirt also forces<br />
water to enter the filtration zone under low velocities.<br />
The separator skirt is attached to the underside of the<br />
cartridge deck.<br />
• Large diameter access lids are installed at the surface<br />
and are removed to allow access for maintenance<br />
of the system. The upper chamber is designed<br />
with tapered surrounds to match with finished<br />
surface grades.<br />
The <strong>JellyFish®</strong> <strong>filter</strong> and components are depicted in<br />
Figure 1 below.<br />
<strong>JellyFish®</strong> <strong>filter</strong><br />
• As an option, the inlet pipe can be located below the<br />
deck for drainage networks with deep invert levels.<br />
In these systems, a deflector plate is installed across<br />
the inlet pipe to induce tangential water flow<br />
through the channel between the chamber wall and<br />
separator skirt.<br />

Membrane filtration cartridge<br />
Figure 2 – <strong>JellyFish®</strong> membrane filtration cartridge<br />
The <strong>JellyFish®</strong> <strong>filter</strong> utilises multiple lightweight<br />
membrane filtration cartridges. Each cartridge consists of<br />
multiple removable <strong>filter</strong> elements (“filtration tentacles”)<br />
attached to a cartridge head plate. Each filtration<br />
tentacle consists of a central perforated tube surrounded<br />
by a specialised membrane. A removable oil-resistant<br />
polymeric gasket provides a watertight seal between the<br />
cartridge and the deck. A <strong>JellyFish®</strong> membrane filtration<br />
cartridge is depicted in Figure 2.<br />

The cartridge length is 1,372 mm. The dry weight of<br />
a new cartridge is less than 9 kg, and the wet weight<br />
of a used cartridge is less than 23 kg. No heavy lifting<br />
equipment is required during exchange.<br />
The filtration tentacle membranes provide a large surface<br />
area, resulting in high flow and suspended sediment<br />
removal capacities. A typical <strong>JellyFish®</strong> cartridge with<br />
11 filtration tentacles has 35.4 m 2 of membrane<br />
surface area. Hydraulic testing on clean <strong>filter</strong> cartridges<br />
demonstrated a flow rate of 11.3 L/s at 455 mm of<br />
driving head.<br />
Extensive independent field testing, including testing<br />
at an urban site with high intensity rainfall and runoff,<br />
has demonstrated consistently high pollutant removal<br />
performance with a conservative design flow rate of<br />
5 L/s for the high-flow cartridges and 2.5 L/s for the<br />
draindown cartridges.<br />
These values translate to a conservative design<br />
membrane filtration flux rate (flow per unit surface area)<br />
of 0.14 L/s/m 2 for the high-flow cartridge and 0.07 L/s/m 2<br />
for the draindown cartridge.<br />
In addition, the filtration membrane has been treated<br />
to allow biofilm to grow but not clog the pores of the<br />
membrane. The flow rating of a particular <strong>JellyFish®</strong> <strong>filter</strong><br />
cartridge is based on the membrane filtration surface<br />
area of the cartridge and data collected from both<br />
laboratory testing and field testing. The cartridge deck<br />
contains apertures for each <strong>filter</strong> cartridge.<br />
4 <strong>JellyFish®</strong> <strong>filter</strong>
System operation<br />
As a tertiary treatment system, the <strong>JellyFish®</strong> <strong>filter</strong><br />
is designed to be an “offline” structure, as part of a<br />
treatment train. For effective operation, the system<br />
requires a difference in elevation between upstream and<br />
downstream water levels. Typically, a minimum 455 mm<br />
of driving head is designed into the system but may<br />
vary from 305 mm to 610 mm depending on specific<br />
site requirements.<br />
The <strong>JellyFish®</strong> <strong>filter</strong> uses gravity, flow rotation and<br />
membrane filtration treatment to remove pollutants<br />
from stormwater runoff. These functions are depicted in<br />
Figure 3 below.<br />
Gravitational forces remove coarse sediment (generally<br />
>50 microns), particulate-bound pollutants (nutrients,<br />
toxic metals, hydrocarbons), free oil and floatable<br />
trash and debris (that may bypass upstream primary<br />
treatment devices). Large, heavy particles fall to the sump<br />
(sedimentation) and low specific gravity pollutants rise to<br />
the surface (floatation) behind the MAW.<br />
Treatment begins when flow enters the system through<br />
the inlet pipe (standard). Below-deck inlet pipes are<br />
offered as an option. Influent enters the MAW zone and<br />
passes through a large opening in the deck to the lower<br />
chamber. The large deck opening and change in flow<br />
direction attenuate the influent flow velocity. Buoyant<br />
pollutants remain on the surface in the MAW zone.<br />

Flow into the lower chamber must then pass tangentially<br />
around the separator skirt protecting the cartridges<br />
and increasing the flowpath length. Coarse sediment<br />
settles out of the MAW zone into the sump. As water<br />
flows tangentially around the separator skirt in the<br />
lower chamber, the large opening in the bottom of the<br />
separator skirt and upward change in direction further<br />
reduces flow velocity and enhances particle separation.<br />
As a result, sediment settles in the sump.<br />
Flows pass through the cartridge in the filtration zone.<br />
Each <strong>filter</strong> cartridge consists of multiple tentacles.<br />
Hydraulic pressure across the entire membrane surface<br />
area causes water to penetrate the filtration tentacles.<br />
Water enters the membrane pores radially and deposits<br />
fine particulates on the exterior membrane surface.<br />
Filtered water flows into the centre drain tube of each<br />
tentacle, the water then flows upward and out the top.<br />
Water exiting the top of the tentacles combines under<br />
the lid, where the combined flow exits the cartridge<br />
through the orifice with a pulsating fountain effect<br />
into the backwash pool. When the water level in the<br />
backwash pool exceeds the weir height it overflows to<br />
the outlet pipe.<br />
Outside the backwash pool, the draindown cartridge<br />
provides treatment at a reduced flow rate (2.5 L/s) and<br />
allows the treated water captured in the backwash pool<br />
to return through the cartridges and balance water<br />
pressure as the storm event ends.<br />
As particles build up on the external membrane surface,<br />
the pores progressively become smaller. This process,<br />
referred to as “<strong>filter</strong> ripening”, significantly improves<br />
the removal efficiency relative to a brand new or clean<br />
membrane. Filter ripening accounts for the ability of<br />
the <strong>JellyFish®</strong> <strong>filter</strong> to remove particles finer than the<br />
nominal pore size. An animation of the <strong>JellyFish®</strong> <strong>filter</strong><br />
operation and maintenance is available at humes.com.au.<br />
Self-cleaning functions<br />
The <strong>JellyFish®</strong> <strong>filter</strong> utilises several self-cleaning<br />
processes to remove accumulated sediment from the<br />
external surfaces of the filtration membranes, including<br />
automatic backwash of the high-flow cartridges,<br />
vibrational pulses, and gravity. These processes have<br />
been confirmed by more than 12 months of full<br />
scale prototype testing. Combined, these processes<br />
significantly extend the cartridge life, maintenance<br />
interval and reduce life-cycle costs.<br />
Automatic backwash occurs with the high-flow<br />
cartridges at the end of each runoff event. This can occur<br />
multiple times during a single storm event as intensity<br />
and driving head varies. As the inflow subsides and<br />
driving head decreases, water in the backwash pool<br />
reverses flow direction and automatically backwashes<br />
the high-flow cartridges, removing sediment from the<br />
membrane surfaces. Water in the lower chamber (below<br />
deck) is displaced through the draindown cartridges.<br />
Vibrational pulses occur as a result of complex and<br />
variable pressure and flow direction conditions that<br />
arise in the deck during operation. During forward flow<br />
a stream of <strong>filter</strong>ed water exits the top of each filtration<br />
cartridge and encounters resistance from the turbulent<br />
pool of water in the backwash pool. Water is forced<br />
through the cartridge lid orifice into the backwash pool<br />
with a pulsating fountain effect. The resulting pulses<br />
transmit vibrations through the deck to the membranes,<br />
thereby dislodging accumulated sediment. The effect<br />
is pronounced at higher flow rates, and influences<br />
all cartridges.<br />
Accumulated sediment on the membranes will settle<br />
under gravity both during inflow events and inter-event<br />
dry periods. As fine particles form into larger masses<br />
on the membrane surface, adhesion to the membrane<br />
surface lessens, and sediment sheds away from the<br />
membrane. Chemical processes and biofilm effects also<br />
play a role.<br />

System performance<br />
The <strong>JellyFish®</strong> <strong>filter</strong> has been designed to provide tertiary<br />
level treatment and may be combined with a Gross<br />
Pollutant Trap (GPT) as part of a treatment train to<br />
optimise overall performance.<br />
Treatment efficiency<br />
Inlet and outlet pipes<br />
An above-deck inlet pipe configuration is standard<br />
for the <strong>JellyFish®</strong> <strong>filter</strong> and an optional below-deck<br />
inlet configuration is available on request. Specific site<br />
constraints generally determine the configuration that<br />
is most favourable. In both configurations, the invert<br />
level of the outlet pipe is identical to the cartridge<br />
deck elevation.<br />
<strong>JellyFish®</strong> <strong>filter</strong><br />
Extensive research of the <strong>JellyFish®</strong> <strong>filter</strong> has proven<br />
its performance under Australian laboratory, US field<br />
conditions and Australian field conditions. Field testing in<br />
the United States has received independent verification<br />
under the stringent New Jersey Corporation for Advanced<br />
Technology (NJCAT) protocol. The results are summarised<br />

Design information<br />
The <strong>JellyFish®</strong> <strong>filter</strong> has many flexible design features to<br />
accommodate a wide range of specific site requirements<br />
and constraints. Please contact <strong>Humes</strong> for assistance.<br />
Configurations and design capacities<br />
For the standard above-deck inlet pipe configuration, the<br />
invert elevation of the inlet pipe is typically set 150 mm<br />
higher than the invert elevation of the outlet pipe. This<br />
generally ensures that the inlet pipe will drain completely<br />
after each rainfall/runoff event, while providing sufficient<br />
volume within the MAW zone for surface accumulation<br />
of floatables below the inlet pipe. The elevation of the<br />
inlet pipe can be varied as required.<br />
<strong>JellyFish®</strong> <strong>filter</strong><br />
Design flow capacities and pollutant capacities for<br />
standard <strong>JellyFish®</strong> <strong>filter</strong> configurations are shown in<br />
Table 2 on the previous page.<br />
The <strong>JellyFish®</strong> <strong>filter</strong> standard model numbers provide<br />
information about the manhole inside diameter and<br />
cartridge counts for high-flow and draindown cartridges.<br />
For example, the <strong>JellyFish®</strong> <strong>filter</strong> model number<br />
JF1800-5-1 is an 1,800 mm diameter structure with five<br />
high-flow cartridges and one draindown cartridge.<br />
The <strong>JellyFish®</strong> <strong>filter</strong> can accommodate a range of angles<br />
between the inlet and outlet pipes. Standard outlet pipe<br />
locations are within a 180° span about the circumference<br />
of the structure (refer to Figure 4 below). The separation<br />
angle relationship of the inlet pipe to the outlet pipe can<br />
vary from 90 to 270 degrees to provide maximum design<br />
flexibility. Contact <strong>Humes</strong> Water Solutions for assistance<br />
with angles outside this range. The <strong>JellyFish®</strong> <strong>filter</strong> can be<br />
installed at a range of depths of cover.<br />
With systems using an external bypass from an upstream<br />
diversion structure, the driving head is calculated as the<br />
difference in elevation between the top of the diversion<br />
structure weir and the invert of the <strong>JellyFish®</strong> <strong>filter</strong> outlet<br />
pipe. A minimum of 455 mm is required to drive the flow<br />
through the <strong>JellyFish®</strong> <strong>filter</strong> at the rates shown in Table 2.<br />
Figure 4 – Typical <strong>JellyFish®</strong> <strong>filter</strong> outlet locations<br />
Inlet<br />
Outlet<br />
Recommended design flows of 5 L/s for high flow<br />
cartridges and 2.5 L/s for draindown cartridges are to<br />
ensure longevity of the <strong>filter</strong>.<br />
Submerged or backwater conditions may be<br />
accommodated in some circumstances and assistance<br />
from <strong>Humes</strong> engineers is recommended.<br />
<strong>JellyFish®</strong> <strong>filter</strong> 9
Bypass design<br />
The <strong>JellyFish®</strong> <strong>filter</strong> should be designed in an offline<br />
configuration for most catchments. All stormwater <strong>filter</strong><br />
systems will perform for a longer duration between<br />
required maintenance services when designed and<br />
applied in offline configurations. A standard offline<br />
configuration has an external bypass that uses an<br />
upstream diversion structure. The elevation difference<br />
between the top of the diversion structure and the<br />
<strong>JellyFish®</strong> <strong>filter</strong> outlet pipe invert should be a minimum<br />
of 455 mm. Excess flow that overflows the diversion,<br />
bypasses the <strong>JellyFish®</strong> <strong>filter</strong>.<br />
For smaller sites an online configuration might be more<br />
suitable. In these cases, an optional internal bypass<br />
pressure relief pipe(s) can be placed in one or multiple<br />
cartridge receptacles within the <strong>JellyFish®</strong> <strong>filter</strong>.<br />
The pressure relief pipe height and diameter can be<br />
varied to accommodate the design peak flow rate and<br />
system driving head requirements. For these systems, the<br />
driving head is calculated as the difference in elevation<br />
between the top of the pressure relief pipe and the invert<br />
of the outlet pipe.<br />
When the internal bypass option is utilised, peak flow<br />
rates receive membrane filtration treatment up to the<br />
filtration design flow rate, with the balance of the peak<br />
flow receiving primary treatment only. In these cases,<br />
increased sump depth may be required to increase<br />
sediment storage capacity and to minimise re-suspension<br />
of previously captured sediment at peak flow rates.<br />
It is also possible to configure this arrangement using<br />
a single diversion structure. Contact <strong>Humes</strong> for design<br />
assistance.<br />

Dry sump option<br />
The <strong>JellyFish®</strong> <strong>filter</strong> can be supplied with a dry sump<br />
option by way of <strong>filter</strong>ing the water collected in the sump<br />
during a rainfall event to an offline soak well.<br />
The captured water is <strong>filter</strong>ed with a horizontally<br />
positioned <strong>filter</strong> “tentacle” that is covered by a stainless<br />
steel shroud for protection at the sump invert.<br />
The release of <strong>filter</strong>ed water is controlled by using an<br />

The <strong>JellyFish®</strong> <strong>filter</strong> is designed to function optimally<br />
under free-surface flow conditions. For systems that<br />
may experience submerged or backwater conditions due<br />
to tailwater or tidal effects, driving head calculations<br />
must account for water elevation during the backwater<br />
condition. The <strong>JellyFish®</strong> <strong>filter</strong> treatment functions<br />

Series <strong>JellyFish®</strong> <strong>filter</strong><br />
For sites with water quality treatment flow rates that<br />
exceed the design flow rate of the largest standard<br />
<strong>JellyFish®</strong> <strong>filter</strong> model, custom systems can be<br />
designed that hydraulically connect multiple <strong>JellyFish®</strong><br />
<strong>filter</strong>s in series. For any design questions or custom<br />
modifications, contact <strong>Humes</strong> for assistance.<br />

System installation<br />
The <strong>JellyFish®</strong> <strong>filter</strong> can be installed by a civil or plumbing<br />
contractor in much the same way as a manhole or other<br />
stormwater drainage structures. It is supplied on-site in<br />
separate, easily identifiable components. The upstream<br />
bypass pit and downstream junction pit are supplied<br />
separately.<br />
The <strong>JellyFish®</strong> <strong>filter</strong> is lowered into place by a crane<br />
or excavator, the components interlock and a tapered<br />
surround can be supplied and rotated to match a surface<br />
grade (if the system is located in road pavement). The<br />
system arrives to the site with the internal parts fully<br />
assembled.<br />
Inspection and maintenance<br />
For inspection and maintenance information, please refer<br />
to the <strong>JellyFish®</strong> <strong>filter</strong> owner’s <strong>manual</strong>.<br />
An animation of the <strong>JellyFish®</strong> <strong>filter</strong> operation and<br />
maintenance is available at humes.com.au.<br />
