The Challenge: Reduce Blue-green Algae Count
The main objective for this project was to reduce the blue-green algae counts in the dam used as water supply. When blooming in the summer, the blue-green algae increases the process costs of the water, or even making the water unusable. A reduction in blue-green algae would also allow for savings in the use of (expensive) chemicals.
The Solution: Ultrasonic Sound Waves
Ultrasound technology combined with real-time water quality monitoring provides a cost-effective solution to control algal blooms. The ultrasonic sound waves provide a long-term solution for a healthy ecosystem and are proven to be safe for humans, plants and other aquatic life.
The Results: 90% Reduction in Blue-green Algae
Since the installation in December 2016 the project appeared to be of great success. The blue-green algae count proved to be 90% lower during the summer compared to the previous year. The real-time water quality data predicts new algal blooms allowing them to be controlled before they become a problem.
“It gives that extra assurance that when people turn on the tap the water that they are drinking is safe.”
