A Smarter Way to Stop the Algae Cycle in Wastewater

Are you tired of trying solution after solution for your recurring algae problem — only to watch it return each season? Many operators have tried ultrasonic systems before, but not all ultrasound is equal. If the signal isn’t strong enough to create true cavitation, it won’t disrupt the gas vesicles inside cyanobacteria (blue-green algae), and the results won’t last.

The build-up of algae doesn’t just look bad — it reduces pond capacity, increases turbidity, releases odours, interferes with natural settling processes, and can even put your consent compliance at risk.

Our industrial-strength ultrasound technology delivers consistent cavitation through the water column, targeting non-motile cyanobacteria before they rise to form surface blooms.

EnviroSonic helps restore the natural process by:

  • Improving settling efficiency — less interference from algae mats and organic build-up.

  • Enhancing clarity sedimentation and treatment systems operate at full capacity.

  • Reducing maintenance — fewer desludging cycles and less downtime.

  • Protecting aquatic ecosystems by eliminating the need for chemical treatments which makes it perfect for wetlands.

  • Supporting consent compliance with consistent water-quality improvements.


Consistent algae control — no more chemicals required at Wauchope

Location: Wauchope Waste Water Treatment Plant is run by the Port Macquarie-Hastings Council in northern New South Wales, Australia.

Size: The EnviroSonic pontoons are located in the final three settlement ponds on site.

Envirosonic: There are two double mounted solar powered pontoons holding two ES300 units in each the final settlement ponds.

Success: The EnviroSonic units have successfully stablised the algae biovolume in the settlement ponds so that the treated water can be released for local irrigation. No chemicals have been required to control algal blooms since EnviroSonic was installed.
