Southeast Queensland Water uses EnviroSonic to control blue green algae

Seqwater has engaged algal control specialists EnviroSonic to investigate the use of ultrasonic technology as an environmentally friendly and cost-effective blue-green algae management measure.

Seqwater Catchment Water Quality Advisor Renee Hague said the technology uses two EnviroSonic solar-powered units emitting ultrasonic sound waves to inhibit the algae from forming intense blooms.

Hague said the success of the trial could result in significant savings to water treatment costs and improved drinking water quality for customers.

“During the trial period, weekly samples taken from Poona Dam, showed a dramatic decline in taste and odour compounds in the dam,” she said.

“As a result, we’ve integrated the permanent use of this technology at Poona Dam, with the potential of rolling out these units at other Seqwater dams prone to blue green algae blooms.”
