Volcanic media research Tube trials conducted with different types of volcanic media to determine water treatment performance. Arris delivers - Research • 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 – Phosphorus Recovery • 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 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 CaPO4 precipitates, Increased availability is believed to be is to be driven by increased root interception and exuding of root complexing compounds Pot Trials Protocol • Identify P responsive soils – – • Add P compounds/products identified in P removal research (phase 1) – • • • Seeking soils with low cation exchange capacity P response curves will be developed using TSP 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 Discussion Issues • Microbiological quality of water – C2 laboratory • Ideal end use of treated water • Access to treated water – Post activated sludge – Pre activated sludge Arris delivers – Coal Seam Gas and mining water solutions • 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.
