Constant aeration is vital for effective wastewater treatment, but how can operators reduce their energy consumption without risking oxygen deficiencies?
Australia’s changing climate and growing urban and industrial demands are putting a strain on vital wastewater treatment facilities. As oxygen levels directly impact the performance of the biological treatment process, operators need to maintain efficient and reliable aeration at all times.
However, as many of Australia’s wastewater facilities age, older aeration technology often uses more energy and might not even be able to keep up with increasing demands, running risk of an oxygen deficiency that often requires extensive maintenance works.
To tackle these challenges two Australian wastewater facilities took an innovative approach to aeration.
No downtime, no hassle
While both treatment plants deployed Mapal Aeration Solutions floating fine bubble aeration system, this technology helped each one overcome a unique set of challenges.
The first wastewater treatment plant in Victoria was able to reduce aeration energy use by more than 40 per cent, while improving ammonia removal efficiency.
This fine bubble aeration technology enhances oxygen transfer, optimising the removal of organic matter, ammonia and other contaminants to ensure compliance with strict environmental regulations.

These aeration systems are also designed to offer unparalleled efficiency and adaptability, and can be integrated seamlessly into both new and existing wastewater treatment infrastructure.
Over in New South Wales, another industry facility was able to meet strict effluent discharge standards while cutting maintenance costs.
Because the fine bubble systems ensure efficient aeration without draining basins, halting operations or requiring personnel to enter the water, they are able to cut maintenance costs and safeguard operators’ valuable time.
Changing the wastewater treatment game
Mapal’s drop-in, retrievable, floating fine bubble aeration systems offer an efficient, adaptable and easy-to-install solution that integrates seamlessly into both new and existing wastewater treatment infrastructure. Key advantages include:
Quick, safe and easy installation: these systems are installed via crane in active aeration reactors, which means no basin drainage, no process disruptions and no personnel required to enter the water.
Versatile compatibility: the aerators are designed for concrete reactors, lagoons, balancing tanks and bolted aeration tanks, and are compatible with existing aeration systems without modifications.
Modular and flexible design: units can be added, removed, or repositioned without halting operations, allowing facilities to scale or adjust as needed.
Supplemental oxygen: this enhances performance during seasonal peaks and system upgrades, floating above existing diffusers or alongside surface aeration.
Robust stainless-steel diffusers: unlike plastic alternatives, these stainless-steel fine bubble diffusers ensure long-lasting durability, clog resistance and high oxygen transfer efficiency.
Customisable air flow and floor coverage: adjustable airflow rates and excellent coverage help optimise oxygen transfer and enhance treatment performance.
Easy maintenance: individual units can be removed and reinstalled with a crane in live working reactors, ensuring continued high efficiency.
Tailored solutions: these units can be customised for any reactor or lagoon, making them ideal for plant expansions, upgrades or new installations.
A balanced approach
Mapal’s aeration technology supports Australia’s sustainability goals by reducing carbon footprints while maximising treatment efficiency. By implementing fine bubble aeration, treatment facilities can significantly lower operational costs while ensuring compliance with stringent effluent regulations.
Additionally, these low-maintenance systems reduce labour costs and extend equipment lifespan, making them a smart long-term investment for utilities and industries.
However, Mapal Aeration Solutions strives to do more than just supply aeration technology – the team collaborates closely with clients to design and implement tailored solutions that meet specific operational needs.
Mapal’s comprehensive support includes consultation, system design, installation, and post-installation assistance, ensuring the long-term success of every project.
As Australia continues to tackle water management challenges, efficient and sustainable wastewater treatment will play a critical role. Mapal is committed to helping utilities and industries improve treatment efficiency, reduce environmental impact, and achieve long-term sustainability through its proven solutions.
