Partner Organisations: Seqwater, Queensland Urban Utilities, Water Research Australia Ltd, District of Columbia Water and Sewer Authority, US

Project Summary
The project aims to develop and demonstrate an integrated and innovative strategy, and the associated science and technologies, to achieve multiple beneficial uses of iron salts in an urban water system. The project intends to use iron chloride to replace the most commonly used alum as a coagulant in water treatment. The same iron is then further used for corrosion and odour control in sewers, phosphorus removal in wastewater treatment reactors and hydrogen sulfide removal from biogas in an anaerobic digester. The strategy is expected to substantially reduce the use of chemicals in the entire urban water system, delivering large economic and environmental benefits to urban water utilities.

Title: Biogeochemistry of ferruginous duricrusts (canna)

Partner Organisation(s): Vale SA

Project Summary
The project is focussed on the examination and application of microbial iron cycling in the formation of geologically stable, iron duricrusts in tropical regimes. The aim of the project is to develop a site-scale bioremediation strategy for iron ore mines by re-establishing canga, which are ‘ancient’ distinct ecosystems possessing unique plant species rarely found on Earth. This university-industry collaboration aims to produce economic benefits for the world’s iron mining industry through advanced training in mining-related research, and through the completion of the mining life cycle by site remediation, enhancing Australia’s position as a global leader in providing innovative solutions to today’s mining challenges.
