Gippsland Water trials nanobubble technology to cut energy use and boost wastewater treatment efficiency

Gippsland Water is trialling nanobubble oxygenation at Neerim South to cut energy use, improve treatment efficiency, and reduce costs, supported by a $50,000 Climate Innovation Challenge grant.

Gippsland Water has launched an innovative nanobubble oxygenation trial at the Neerim South wastewater treatment plant. Funded by a $50,000 prize from the Victorian Water Minister's Climate Innovation Challenge.

Gippsland Water has launched a nanobubble oxygenation trial, with the unit delivered to Neerim South wastewater treatment plant recently

Energy efficient treatment

The trial aims to replace the current mechanical aeration process with the use of 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," Ms 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," Ms Cumming said.

Nanobubble technology trial

Ms 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."

The trial will wrap up in October 2025 and will be completed in partnership with the supplier of the nanobubble technology, Custom Fluids. For more information about the Water Minister's Climate Innovation Challenge, visit Water Minister's Climate Innovation Challenge website.
