The standard maintenance approach is designed to
work towards keeping the Jellyfish® system operational
during normal conditions. From time to time, events

on site can make it necessary to perform additional
maintenance to ensure the continuing performance of
the device.

Hazardous Material Spill

If there is a spill event on site, the Jellyfish® unit should
be inspected and serviced accordingly. Specifically,

all captured pollutants and liquids from within the unit
should be removed and disposed in accordance with any
additional requirements that may relate to the type of spill
event. Additionally, it will be necessary to inspect the filter
cartridges and assess their contamination, depending on
the type of spill event it may be necessary to replace the
filtration cartridges.

Blockages

The Jellyfish® treatment system is designed to operate
in an offline arrangement, where an upstream high
flow bypass structure is in used. In the unlikely event
that flooding occurs upstream of the Jellyfish® system,
the following steps should be undertaken to assist in
diagnosing the issue and determining the appropriate
response.

a Inspect the upstream diversion structure to ensure
that it is free of debris and pollutants

Inspect the Jellyfish® unit checking both the inlet
and outlet pipes for obstructions (e.g. pollutant
build-up, blockage), which if present, should be
removed

Major Storms and Flooding

In addition to the scheduled activities, it is important to
inspect the condition of the Jellyfish® after a major storm
event. The focus is to inspect for damage and higher
than normal sediment accumulation that may result
from localised erosion. Where necessary, damaged
components should be replaced and accumulated
pollutants should be removed and disposed.
