Standards & Guidelines for
Petrol Station Stormwater
Pollution Control
There is no Australian Standard for oil/water separators.
There are only guidelines for hydrocarbon discharge
limits for stormwater discharge.
All State and territory regulating environmentalauthorities (or EPA) have guidelines with varying
terminology stating that hydrocarbons are not to be
visual (10ppm) in stormwater and receiving waters.
European Standard(oil and petrol separators)
In the absence of an Australian Standard, the
European British Standard 858.1 applies when
compliance is the regulating issue.
It is the worlds most stringent standard for
hydrocarbons separation for the use of oil/petrol
separators in surface water drainage systems.Prevents the emission of petrol odours.

Solution for
Non-Compliant
Petrol StationsSPEL Puraceptor Class 1stormwater
treatment system is a solution for the
treatment, capture and retention of
hydrocarbons off petrol stations.
SPEL Puraceptor Class 1can
rationalize the existing use of servicestations in conformity with the applicable
environmental guidelines and put in place
ongoing operational measures to prevent
the likelihood of contamination in the
case of an unforeseen future event.
SPEL`s Puraceptor Class 1oil/water
separator is connected to the stormwater
[provides the site with the highest degree
of environmental protection; - a protection
that complies with the councils, and the
EPA`s guidelines.]
Petrol forecourt and surrounds at a busy metropolitan petrol station rendered compliant. The
catchment consists of a grated drain encompassing the complete perimeter of the under-sized
canopy. Surface water and forecourt runoff drains to the Puraceptor located under the two
trafficable covers in the foreground.
Puraceptor CertificationAustralian Independent Tests
The Puraceptor has been independently tested at Australia`s pre-
eminent hydraulics research facility, the University of South Australia
(UNISA), and at the UK`s leading hydraulics research faculty HR
Wallingford.
NATA analysis of the tests shows a water quality of no visible trace` of
hydrocarbons from an inflow concentration of 5,000ppm.
In-Situ TestingNATA analysis of Puraceptors operating at similar applications inAustralia reveal `no detection` of hydrocarbons from a captured
concentration of 8,000ppm.
Council ApprovalsThe increasing awareness by councils of the superior European Standard
has prompted many to review their current procedures and in only the
past eighteen months over sixty councils have approved SPEL for service
stations and similar applications with units already operational in excess
of forty sites.
Puraceptor Benefits
Full retention Class 1 treatment oil/water separator. It
treats all liquid. There is no bypass.
Complies with federal and state government regulating
environmental guidelines for water quality.
University tested and certied to independent
European Standard EN BS 858.1 for the capture and
retention of hydrocarbons with a discharge quality of
no visible trace from a tested inflow concentrator of
5,000ppm.
Capture and contain oil/fuel spillages.
Can be sized to capture and contain a spill from a
refuelling tanker and prevent discharge to stormwater.
Passive gravity function ensuring treatment is
continuous.
Equipped with an intrinsically safe oil alert probe
providing regular detection for oil build-up. Set to alarm
when oil hydrocarbons attain 10% of the chamber`s
volume.
Oil alert probe enables self-monitoring`, suitable forunmanned and remote locations.
Equipped with a ame trap ensuring re water is
extinguished.
Equipped with a vapour trap preventing vapours from
discharging and preventing the emission of odours.
Water tight structure
Minimum 50 years life span.
Low frequency and low cost maintenance
Operations & Maintenance manual
with a ledger for accurate recording ofmaintenance operations.
Maintenance performed from ground level; no
entering of tank is required, satisfying O.H.& S.
requirements.

Stormwater discharge quality is < 1.86 mg/l hydrocarbon
contentexceeding the Environmental Protection Agency
(E.P.A.) requirements of 10mg/l hydrocarbon content.
Test sampling access:Field test discharged samples are
taken from sampling point and analysed by NATA
accredited laboratories.
SPEL PURACEPTORunits are glass reinforced plastic
vessels made by the technical advanced chop hoop filamentwinding process (patented) producing circumferential and
longitudinal strength complying with AS 2634-1983 for tank
design.
SPEL PURACEPTOR Class 1separators
incorporate coalescer units. They
consist of a quality stainless steel
mesh container with an adjustablehandle and high volume reticulated
foam insert.
The coalescer unit is mounted in
the second chamber, providing
a coalescence process for the
separation of smaller globules of light
liquid pollutants before final discharge
to stormwater.
SPEL PURACEPTOR tanks contain an immersed inlet
dip pipe to extinguish flames and prevent inflammable
vapours form passing through to the drainage system.
Complies with Section 6.3.4 of BS EN 858.1.2006.
SPEL PURACEPTOR can withstand temperatures of up
to 140C.
OilRetentionChamber
Secondary
Separation
Chamber
The probe is freely suspended in the probe protection tube
in the separator at the correct level. When the oil-layer or
depth of hydrocarbons reaches the predetermined level, the
top of the probe will be immersed in the oil, breaking the
circuit and activating the alarm. It is intrinsically fail-safe`
system providing complete assurance that is operative. If a
fault occurs it will be signaled immediately.
TheAUTOMATIC CLOSURE DEVICE (A.C.D.) is a precisely
engineered device comprising a water-buoyant ball
that is sensitive to any change in the water density as a
consequence of light liquids build up, thereby automatically
activating a process of depressing the A.C.D. to SHUT OFF
the separator, preventing pollutants from discharging to
drains and waterways.
MAINTENANCE Designed for high performance and low maintenance over a long life span
Visible oils (TPH) are skimmed from the surface of the water level
Easy and safe to access and clean, with access shafts positioned onall chambers.
No entering of the unit is required
Not mandatory for the unit to be cleaned every 3 months.
Only oils, sediment and gross pollutants need to be removed.
All stormwater does not require removal.
The cylindrical design ensures sediment collects easily on the floorof the chambers effecting easy, quick removal. There are no squarecorners or unreachable cavities and recesses.
Waste is removed by a vacuum loading truck. (Suction truck)
