Water treatment at 4000m/13,000ft height

Posted: Thursday 12th July 2018

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. The LG Sonic MPC-Buoy is a unique environmentally friendly solution that monitors and control algae in large water surfaces.

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 4000m/13,000ft height, the online water quality software of LG Sonic, MPC-View is significant. The software provides insight into the water quality, algae trends, and progress of the ultrasonic treatment. Furthermore, the software shows technical parameters, such as the status of the ultrasonic transmitters, signal strength and the battery strength.

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 Colombia, United States, United Kingdom, New Zealand, among other countries.
