A new ‘Turbolox’ oxygenation plant has been unveiled as part of a revolutionary approach to caring for the Swan and Canning rivers in Australia, and combating the effects of climate change.
Environment Minister David Templeman noted the new oxygenation plant was part of the Carpenter Government’s $40m Healthy Rivers Action Plan and increasing oxygen levels in the upstream areas of the rivers.
“The Healthy Rivers Action Plan is a comprehensive ‘catchment to coast’ approach to protecting the future of our rivers by improving water quality,” Templeman explained.
The Minister noted how recent studies into climate change impacts on the Swan-Canning river system found oxygen levels in the upper stretches were likely to decrease in coming years.
“The Swan River is the very heart and soul of our community. Just like other rivers around the world, the Swan and Canning rivers are susceptible to algal blooms, low oxygen levels and seasonal fish deaths, and these are exacerbated by the onset of climate change.”
“The new Turbolox unit will work more efficiently in the upper Swan than its predecessor, by adapting to river conditions to spread oxygen further. It is essential that we continue to develop and adopt innovative technologies to deal with river water quality issues, and oxygenation is just one technique we are using.”
The Turbolox system is believed to have been invented by BOC employees, Merv Ogston and Jim McAndrew as the most efficient way to completely dissolve the oxygen and treat sewage for hydrogen sulphate odours.
The oxygenation of the wastewater reduces odours from the pumping stations and prevents the wastewater from becoming septic whilst in transport to a treatment facility.
A system that treats 10% of the main line flow in a concentration that achieves the desired result of the entire flow, the 10% of treated wastewater is pressurised by a dry mounted, water jacketed sewage pump. Once pressurised by the pump, the sewage is treated by oxygen using side stream, high shear dissolution dissolving technology developed at BOC Gases.
