Florida is investigating the use of sound waves to target and kill algae in Lake Okeechobee. According to LG Sonic, last year, the state of emergency had to be declared in several counties following severe algal blooms throughout the state.

This year, Florida commissioners want to prevent algal bloom disasters by using a chemical-free solution that uses ultrasound technology to get rid of algal blooms, according to LG Sonic.

CTO of LG Sonic Lisa Brand was invited by the City of Miami to present this solution at the Smart Cities event. During the event, challenges and solutions to issues of resilience, climate change, storm water management, and harmful algal blooms were among the topics discussed.

The sound waves developed target and neutralize the algae, preventing them from growing and evolving to a blooming stage. According to LG Sonic, these sound waves are harmless to humans, fish, and other aquatic life. For each type of algae, such as Cyanobacteria, the wave has a specific “song” to target the algae.

By using real-time water quality monitoring and satellite data, the manufacturer is able to predict algal blooms days in advance. This allows the ultrasound technology to neutralize the algae before they become a problem. LG Sonic has built a database of algae and water quality data which allow applying the right treatment for a specific type of algae at the right time.

According to LG Sonic, the technology is already being used in more than 15 countries worldwide, including the U.S. The technology has helped American Water to control algal blooms and eliminate chemical usage for their drinking water reservoir in New Jersey. This allowed them to ensure safe drinking water to their customers.

For many years, Lake Okeechobee has been suffering from algal blooms. According to LG Sonic, this is impacting not only the lake itself, but also the waterways throughout the state. Commissioner Brian Hamman is pushing for the technology to be used at hot spots in Lake Okeechobee. He hopes that the buoys can be used as soon as possible.
