Eight MPC-Buoy systems installed at 4000m height

LG Sonic successfully installed eight MPC Buoy systems in the Salve Faccha reservoir to monitor and control algal blooms. The reservoir, located in a far-off area, is one of the main providers of drinking water to the city of Quito, Ecuador.

To lower the algae levels and improve the water quality in the Salve Faccha drinking water reservoir, eight solar-powered algae control systems were installed. Two weeks after the installation of the MPC-Buoy systems, significant improvements were made in the water quality.

Importance of real-time water quality monitoring

Salve Faccha reservoir is a water reservoir located in the highlands of Quito, Ecuador. The reservoir is used as a drinking water source and provides approximately 40% of the drinking water to the city of Quito. To challenge algae problems in the reservoir, eight MPC-Buoy systems were installed to control algae effectively. Because of the location of the reservoir, at 4000 meters height, the online water quality software of LG Sonic, MPC-View is significant. Thanks to the software, the water quality of the reservoir can be monitored easily.

Ultrasound technology as an environmentally friendly solution

The MPC-Buoy system controls algae in large water surfaces, using real-time water quality monitoring and remote sensing to analyse current algae and to predict algal blooms. The technology is based on ultrasound, which can effectively control algae by specific frequencies and amplitudes. The technology is environmentally friendly and safe for fish, plants, and zooplankton. At the moment, the LG Sonic MPC-Buoy is installed in lakes and water reservoirs in the United States, Canada, United Kingdom, and Malaysia among other countries.
