3. Arris Water Small business formed from University research outcomes Maintained a strong research focus Currently sponsoring 3 post-graduate positions Also providing industry placement positions for students working on mini- thesis components of subjects

4. Non-typical wastewater or water problems benefit from thorough and detailed research programs. Arris Water conducts research in the mining, industrial and residential sectors. Arris has the capacity to undertake research independently or our strong links to the Central Queensland University and the Waite Campus of the University of Adelaide facilitate collaborative research approaches. Arris is committed to research and education in the water sector. Volcanic media research Tube trials conducted with different types of volcanic media to determine water treatment performance. Arris delivers - Research

5. Arris has focused its research on providing ‘fit-for-purpose’ recycled water This has involved the removal of various contaminants of concern Arris is researching novel techniques for the capture and recycling of phosphorus from treated effluent. Our research projects commonly involve agricultural irrigation Agricultural Production Research In-field lettuce trials. Arris delivers - Research

6. The Arris research program will be completed in 4 phases Removal of P from treated water Regeneration of recovery media Evaluate Ion Exchange Assess P-bioavailability Arris delivers – Phosphorus Recovery

7. Phosphorus Bioavailability CSIRO research has changed the understanding of what P is bioavailable P that has traditionally thought of as unavailable, has been shown to be in fact available over time when no other P sources are present Compounds include CaPO 4 precipitates, Increased availability is believed to be is to be driven by increased root interception and exuding of root complexing compounds

8. Pot Trials Protocol Identify P responsive soils – Seeking soils with low cation exchange capacity – P response curves will be developed using TSP Add P compounds/products identified in P removal research (phase 1) – P additions will be matched to those developed in P response curve study Plot out wheat plants Grow for 5 weeks Measure – Biomass – Total P – Haun Growth Stage

9. Discussion Issues Microbiological quality of water – C2 laboratory Ideal end use of treated water Access to treated water – Post activated sludge – Pre activated sludge

10. Arris has developed technology that can reduce the Sodium Adsorption Ratio (SAR) by over 95% while also significantly lowering the salinity. Arris can successfully decrease the concentrations of heavy metals and hydrocarbons. Arris, in conjunction with the CQUniversity, is conducting research into the efficacy of its patented, trade-secret ion exchange technology for the remediation of associated/co-produced water.  Associated water may contain several contaminants of concern; including sodicity, salinity, strontium, chlorides, bromide, boron, various fraccing chemicals and fluoride.
