In August 2018 we began a new project in Dubai in collaboration with the Dubai Municipality to control algal blooms in the Al Qudra lakes. The lakes were created by the municipality as part of a project to enrich this part of the Dubai desert.

The Dubai Municipality selected MPC-Buoy systems to control algal blooms due to our chemical-free technology and real-time water quality monitoring capabilities.

The project has been a great success, with massive improvements in water quality.

Massive improvement in water quality

The lake, which is used for irrigation purposes, was suffering from severe algae growth. The entire surface was covered with dark green filamentous algae mats. In irrigation reservoirs, algal blooms cause problems by clogging the pumps and nozzles used to irrigate crops and nurseries. 60 days after installation, the chlorophyll-a concentrations of two irrigation reservoirs at the same site were compared.

One irrigation reservoir was treated with the MPC-Buoy while the other reservoir remained untreated. The images below show the massive improvement in water quality produced by the MPC-Buoy treatment of algal blooms.

Interactive algae control

The ultrasound technology used by MPC-Buoy was developed by monitoring algae and water quality parameters all over the world. With this information, a database of specific ultrasonic frequencies and amplitudes for optimal algae treatment has been created. This solution, called Interactive Algae Control, allows the ultrasonic sound waves to be adapted to specific algal types and water conditions. The ultrasonic sound waves developed by LG Sonic have proven to be safe for humans, fish and other aquatic life. A recent study commissioned by the Dutch water board and conducted by the research agency Ecofide, has found no negative effects of the MPC-Buoy on zooplankton.

At the moment, LG Sonic is running algal bloom control projects in drinking water reservoirs, cooling ponds and irrigation reservoirs around the world. Most recently, new projects were implemented in California and Georgia.
