Solution for
Non-Compliant
Petrol Stations

SPEL Puraceptor Class 1 stormwater

treatment system is a solution for the

“satment, capture and retention of
focarbons off petrol stations.

SPEL Puraceptor Class 1 can
rationalize the existing use of service
stations 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 1 oil/water
separator is connected to the stormwater
[provides the site with the hignest degree
of environmental protection; - a protection
that complies with the councils, and the
EPA‘s guidelines.]

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 certified to independent
uropean Standard EN BS 858.1 for the capture and
ois: 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 chambers
volume,

* Oil alert probe enables ‘self-monitoring’, suitable for
unmanned and remote locations.

© Equipped with a flame trap ensuring fire 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

iperations & Maintenance manual
with a ledger for accurate recording of
maintenance operations.

¢ Maintenance performed from ground level; no
entering of tank is required, satisfying O.H.& S.
requirements.

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.

Puracepter Certification
Australian 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.

* NAIA analysis of the tests shows a water quality of no visible trace of
hydrocarbons from an inflow concentration of 5,000ppm.

In-Situ Testing
NATA analysis of Puraceptors operating at similar applications in

Australia reveal ‘no cletection’ of hydrocarbons from a captured
concentration of 8,000ppm.

Council Approvais

The 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,
