Florida Gulf Coast University chooses LG Sonic technology to control algal blooms

With rising temperatures and extreme summer weather, toxic algal blooms are a pressing threat to the water quality of lakes and drinking water reservoirs.

To control algae, FGCU’S Everglades Wetland Research Park in Naples will use LG Sonic’s MPC-Buoy systems.

The Florida Department of Environmental Protection awarded FGCU’s Everglades Wetland Research Park in Naples the grant to run a pilot project. Director Bill Mitsch says “It’s a big grant. It sounds awesome because it’s a million-dollar grant”.

The LG Sonic water treatment buoy called MPC-Buoy, monitors water quality in real-time and based on this data, it sends adjusted ultrasonic frequencies. LG Sonic ultrasound fixes the algae in the water column and prevent them from absorbing sunlight that is essential for photosynthesis. This prevents algae from blooming. The devices are proven to reduce up to 90% of algae while not affecting fish and other aquatic life.

“So there are no chemicals involved in this, this is a non-chemical way of sort of disrupting blue-green algae,” Mitsch said “The company we’re working with has also figured out a way to program the sonic signals for specific algae. They’re really getting sophisticated with this kind of stuff”.

LG Sonic, the manufacturer of MPC-Buoy systems, implemented its technology in 96 countries worldwide. With a track record of 87% of algae reduction in a 1700 acres hydroelectric dam, LG Sonic recovers water bodies of top-level water utilities, power plants, recreational lakes, among others.

“Looking forward to working with the FGCU team to help Florida in it’s fight against Algal Blooms. Our systems have accumulated 20+ million water quality and algae related data sets, based on which our algorithm is able to select frequencies to optimise treatment to the specific algae that is present. We are confident our system will help solve Florida’s algae problems” said Greg Eiffert, Director of LG Sonic US.

This technology has also helped American Water to successfully control algal blooms and eliminate chemical usage for their drinking water reservoir in New Jersey. Director Bill Mitsch also says if this pilot project ends up with success, they could scale it up to larger water bodies, such as toxic blooms at lake Okeechobee.
