Waste water treatment plant: Settlement pond

Stable algal biovolume, no chemicals required

Location: Wauchope waste water treatment plant is run by the Port Macquarie-Hastings Council in northern NSW.

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

Envirosonic: There are two double-mounted solar-powered pontoons holding four ES300 units in each of the three ponds. The units were installed in [year].

Success: The EnviroSonic units have successfully stabilised 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.
