Ultrasonic Algae Control Technology

Ultrasonic algae control technology can reduce up to 90% of the existing algae and prevent the growth of new algae. LG Sonic’s biofouling solutions lower algae, biofilm formation and reduce chemical consumption.

Ultrasonic Algae Control benefits

The ultrasonic algae control devices emit specific ultrasonic parameters in order to control algae and biofouling in lakes, reservoirs, and industrial applications.

      • Eliminate up to 90% of existing algae and prevent new algae
      • Chemical-free solution that is safe for fish and other aquatic life
      • Treat large water surfaces, such as lakes and reservoirs
      • Requires little maintenance to prevent frequent site visits

What is the Impact of Ultrasound on the algae?

We use scientifically proven ultrasonic frequencies to control many types of algae. A very common differentiation is between green algae and toxic cyanobacteria, which are also known as blue-green algae.

1. Create a sound barrier

Blue-green algae and some green algae are capable of travelling through the water vertically due to their possession of gas vesicles. The ultrasonic sound waves create an ultrasonic pressure in the top layer of the water.

2. Lack of light

This ultrasonic sound barrier prevents the algae from rising to the surface and absorbing light for photosynthesis. Therefore, algae are no longer capable of growing further.

3. Control algae growth

The algae will die while the cell wall remains intact, preventing the release of toxins from the algae into the water. The algae will sink to the bottom of the water reservoir and are degraded by the bacteria present.

Safe for humans, fish, plants, zooplankton, and insects

The effects of our ultrasonic algae control products have been tested by various universities and are proven to be safe for fish, plants, zooplankton, and insects.

The University of Portsmouth, UK; UNICET Catania, Italy; and BOKU, Austria found that LG Sonic units are safe for fish. The devices have been tested on their effect on zooplankton, and no negative effect was found. The products are not based on cavitation, which is a phenomenon where high-power ultrasound causes the formation of micro-bubbles that implode, causing intense heat pressure. These processes can destroy cells and might harm fish and plants.


Real-time Water Quality Monitoring for effective algae control in large water surfaces

Based on real-time water quality data we are able to modify the ultrasonic program to the specific water conditions.

The real-time water quality monitoring is automatically integrated in the MPC-Buoy system. The MPC-Buoy contains detailed monitoring equipment, providing a complete overview of the water quality and controls the algae accordingly by using ultrasound. Web-based software (MPC-View) allows users to visually follow the water quality and the progress of the ultrasonic treatment.

Map algae concentrations with Satellite Remote Sensing

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

LG Sonic has integrated the satellite remote sensing technology to accurately map the spatial and temporal distribution of the water quality parameters to generate a complete overview of the algae distribution in large water bodies.

Chameleon Technology™ to control algae in smaller water surfaces

Unique Chameleon™ technology allows to adjust the ultrasonic program to the specific water conditions.

The LG Sonic e-line has 12 ultrasonic programs to effectively control different types of algae in ponds, wastewater treatment plants, and other applications.

Chameleon Technology™ makes it possible to change the ultrasonic program according to the water conditions, type of algae, and type of application, thereby providing the most effective solution for each specific situation.

Real-time Water Quality Monitoring systems

Continuous water quality monitoring combined with web-based software allows for an early warning of toxic algal blooms in lakes, seas, and desalination plants.

A floating buoy system measures essential algae indicators (Chlorophyll-a, Phycocyanin, and Turbidity) and water quality parameters (Dissolved Oxygen (DO), Redox, pH, and Temperature) in order to monitor the water quality. The measured data can be viewed in real-time via a web-based software called the MPC-View.

Prevent Biofouling using ultrasound technology

Control biofouling and reduce chemical dosage with the LG Sonic industrial line.

The ultrasound prevents the biofouling from attaching to cooling basins, industrial equipment, and sea chests.
