欧洲杯开户 and his team at Murdoch have a long history in wastewater treatment research, collaborating with companies in the industry since 2001. They have studied the individual biological steps required to convert nitrogen-containing compounds through to nitrite and nitrate and its eventual removal as nitrogen gas. By separating out these aerobic and anaerobic processes they demonstrated how each could be optimised, giving the potential for improved performance compared to conventional wastewater treatment processes.

欧洲杯开户They developed a process of Parallel Nitrification and Denitrification (PND), which reliably achieves faster and more complete nitrogen removal than existing wastewater systems by sidelining nitrate production. This also uses less oxygen and subsequently requires less energy for aeration than conventional treatment plants. 

欧洲杯开户After the team piloted the underlying technology at the WA Water Corporation’s Woodman Point wastewater treatment plant in 2003, they developed PND from concept to a reliable long-term process ready to be up-scaled. The PND process was licensed in Australia to the , the team’s long-term industry collaborator.

欧洲杯开户In 2016, Downer installed PND as part of the upgrade to a 1 ML/day wastewater treatment plant in Proserpine, Queensland. In a newly built 3.5 ML/day wastewater treatment plant in Mareeba, Queensland, the company incorporated PND into one of its two parallel bioreactors. Each plant discharges waste water into highly sensitive ecosystems, including the Great Barrier Reef (Proserpine). Both plants are currently undertaking benchmarking trials to quantify the effectiveness of PND operation compared to normal operation. By demonstrating the potential of the technology, the Downer group and the Murdoch team are de-risking the broader uptake of PND in the wastewater industry.
