Solar-powered Algae Control using sound waves

The solution is to anchor one or multiple MPC-Buoy systems that transmit specific ultrasonic parameters depending on the type of algae. Each device can control algae in areas up to 500m/1600ft in diameter.



Algae control Benefits

Effective algae control

Eliminates up to 90% of existing algae and prevents the growth of new algae. Furthermore, the MPC-Buoy allows reduction of TSS, BOD, and chemical consumption.

Safe for the environment

The ultrasound used by LG Sonic is safe for fish, plants, zooplankton, and insects. Our devices use of low power (5-20 Watts), wherefore no high voltage is transmitted into the water

No release of toxins

The cell wall of the algae remains intact, preventing the release of toxins from the algae into the water.

Effective on larger water surfaces

Each MPC-Buoy device can control algae in areas up to 500m/1600ft in diameter. Multiple buoys can be installed for large water surfaces.

Low operational costs

The system operates autonomously on solar energy and has an integrated Aquawiper to prevent frequent site visits.

Easy to install and maintain

Can be deployed quickly and easily without the need for a crane. The system is easily accessible for maintenance while deployed.

How it Works

Control and monitor algae concept


1. Monitor Water Quality

The MPC-Buoy provides a complete overview of the water quality by collecting the following parameters every 10 minutes: Chlorophyll α (green algae), Phycocyanin (blue-green algae), pH, Turbidity, Dissolved Oxygen, and Temperature.

2. Predict Algal Blooms

The collected data is delivered in real time via radio, GPRS, or 3G to a web-based software. Based on our developed algorithm we are able to modify the ultrasonic program to the specific water conditions and predict an algal blooms a few days ahead.

3. Control Algae

Based on the received information, the ultrasonic program can be activated according to the water conditions and type of algae present. This way, it is possible to eliminate existing algae and prevent the growth of new algae.

Safe for fish, plants and other aquatic life

Map algae concentrations with Satellite Remote Sensing

Satellite remote sensing technology allows to accurately map the algae distribution in large water bodies.

With the MPC-Buoy, it is already possible to accurately detect algae species in a specific area. By integrating satellite remote sensing it is possible to generate a complete overview of the spatial distribution of algae in large water bodies.

Advanced water quality Software

Based on real-time water quality data LG Sonic is able to modify the ultrasonic program to the specific water conditions.

MPC-View software allows users to visually follow the water quality and the progress of the ultrasonic treatment. Our employees receive the same real-time water quality data to verify the current status of the lake, modify the ultrasonic program, and prevent new blooms.

Easy Installation and Maintenance

The MPC-Buoy can be deployed quickly and easily without the need for a crane. The system is easily accessible for maintenance while deployed.

MPC-Buoy and LG Sonic Monitoring are modular units that are easy to assemble and install. Because the construction is light, you only need a small boat to drag the device to the center of the lake, where the unit can be installed and moored.

Read case study

Four solar-powered algae control buoys were installed in the Canoe Brook Reservoir #1 in Short Hills, NJ to assess the impact of the system for controlling algae and cyanobacteria in the raw water reservoir. The four buoys operated for five months in the spring/summer 2014.

Extensive testing conducted during 2014 showed that the buoys had a significant impact on the algae, allowing the plant to reduce chemical consumption by more than 20 percent, and reducing the concentration of undesirable taste and odor causing compounds in the treated water delivered to customers”.

LG Sonic is running MPC-Buoy projects in more than 20 countries worldwide
