Rosedale plant's energy-efficiency ranking hits top five
Our Rosedale Wastewater Treatment Plant has been named in the top five most energy-efficient plants in Australasia.
Rosedale ranks number five out of 22 in the Water Services Association of Australia’s 2017 survey of plants with activated sludge treatment and on-site co-generation.
Wastewater technology manager Paul Bickers says the top-five ranking was an outstanding outcome.
“It shows that, in terms of technology and efficient plant management, we’re comparable to large plants in Australia,” he says.
“And when it comes to energy efficiency, Rosedale has the advantage that the wastewater treatment process uses gravity to move flows around the plant, so the only pumping required is for the solids process. We also have natural UV disinfection that occurs in the ponds, so a lot of the time we can turn off the UV plant and rely on the sun instead.”
