            1.1        Objectives

            The overall objective of this report is to demonstrate that the SPEL Puraceptor can treat the stormwater runoff
            to remove hydrocarbons providing superior advantages to the suggested design by Council (i.e. Blind Sump),
            and to demonstrate that it can isolate and retain a spill should it occur.


            1.2        Scope

            The scope of this document includes the following:

                      demonstrate the operation of the Puraceptor is equivalent or better than the conditioned set up of a
                       blind sump for a large amount of hydrocarbon spill;
                      presentation of the testing results of both laboratory and field installations for hydrocarbon removal;
                       and
                      Discussion of applications in under-canopy and other sites areas.



            2.0        The SPEL Puraceptor
            The SPEL Puraceptor is a full retention oil separator that treats the runoff generated from fuel stations. It is sized
            to contain more than the anticipated maximum oil spillage (industry standard practice is 8,000L) enabling it to
            be fully operational at all times. The flow tests conducted by the University of South Australia Hydraulics
            Research Laboratory (UniSA) and at HR Wallingford United Kingdom confirms that the unit complies with the
            European Standard BS EN 858.1.2006. The Australian Runoff Quality Handbook (ARQ) makes several references
            to the BS EN 858.1.2006 standard in chapter 9 (Hydrocarbon Management). The SPEL Puraceptor achieves a
            water discharge quality of less than 5 mg light liquids per litre, complying with European Standard BS EN 858
            (Appendix 1). Treatable flow rates range from 2 L/sec to 200 L/sec and its pipe sizes range from 100mm to
            450mm. SPEL Puraceptor units are glass reinforced plastic vessels made by the technical advanced chop hoop
            filament winding process (patented) producing circumferential and longitudinal strength complying with BS4994
            FRP Pressure Vessel code and AS 2634FRP Chemical Equipment to ensure the construction meets the necessary
            strength and stability requirements. The tank is designed to accept ground conditions with low stiffness down
            to 4.8MPa, water tables are set to ground level as standard with a minimum depth of cover, based on a standard
            soil density.

            The treatment efficiency in SPEL Puraceptor Class 1 is:

                      >99.9% hydrocarbons reduction
                      >97% sediment reduction for median particle size distribution 70µm
