            worldwide regard less than 10 ppm as being the benchmark for no visible trace or sheen. Table 1 shows that
            discharge water quality reduction remains constant at <0.1ppm of TPH translating to `no visible trace` from a
            constant inflow concentration of 5,000ppm. The detail of the testing can be reviewed in Appendix 3.

            The Hydrocarbon mix used for the University of South Australia testing program was formulated to replicate the
            carbon fraction breakdown that we see in the field on service stations all over Australia. The NATA detection
            instruments detect all forms of hydrocarbon as in free phase, emulisified and dissolved fractions. The C6 – C9
            fraction represents the BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) constituent of the mix.

            Results show below detection levels of hydrocarbons of all carbon fractions except for C15-C28 with the level
            just above the EQL at 0.162ppm. This is still less than the 10ppm target.

            Independent Standard and Validation

            The British Standard and the independent validation applied to the SPEL Puraceptor™ separators provides the
            council the appropriate latitude to assess the product and the catchment design unencumbered by commercial
            partiality. Please refer to the test data in Appendix 3.
