Gippsland Water has launched an innovative nanobubble oxygenation trial

at the Neerim South wastewater treatment plant.

The trial, funded by a $50,000 prize from the Victorian Water Minister’s

Climate Innovation Challenge, aims to replace the current mechanical

aeration process with nanobubble oxygenation technology to reduce

electricity use during wastewater treatment.

Managing director Sarah Cumming said if successful, the trial could lead

to reduced energy consumption and potential cost reduction.

“Every dollar we can save by making our treatment processes more efficient

helps to put downward pressure on customer bills,” Cumming said.

Nanobubble oxygenation works by creating smaller bubbles, which improves

wastewater treatment by reducing the operational time of energy-intensive

equipment such as pumps and motors.

“This enhances operational efficiency of the treatment process and improves

environmental water quality,” Cumming said. “If our trial results are positive,

we plan to permanently install this technology at the Neerim South wastewater

treatment plant and explore opportunities for other sites.

“We’ll also share our findings with the broader Victorian water industry, and there

is potential the technology could be rolled out more broadly around the state.”
