Reduced blue-green algae counts in New Zealand

Reducing blue-green algae counts

In the Lower Nihotupu Dam in Auckland, New Zealand, five solar-powered algae control systems are controlling blue-green algae blooms. The project started in December 2016 and it proved to be a great success. The algae counts have significantly decreased over the summer, as compared to the previous year.

The water utility’s main objective was to reduce blue-green algae counts in a dam used as a water supply. During summer, algae blooms can cause damage and increase the process costs of the water.

Ultrasound technology

The ultrasound technology combines real-time water quality monitoring and is a cost-effective solution for controlling harmful blooms. LG Sonic’s unique ultrasound is the long-term solution for maintaining a healthy aquatic ecosystem. It’s chemical-free, and has been proven safe for humans, plants, animals, and other aquatic life.

Results

Since installing the MPC-Buoy in December 2016, the project became a great success. Algae counts dramatically decreased during summer, as compared to the previous year.

The real-time water quality data continuously predicts future algae blooms, allowing the utility to control their growth before they become a problem.
