WEFTEC Report: LG Sonic Introduces Solar-Powered Buoy for Algae Control

LG Sonic recently presented the MPC-Buoy for algae control in the Innovation Pavilion at WEFTEC in Chicago. The system is designed to eliminate up to 90% of algae in applications such as drinking water reservoirs, wastewater lagoons and lakes.

The buoy is a floating, solar-powered system that combines real-time water-quality monitoring and ultrasonic sound waves. It helps prevent the growth of new algae while also reducing BOD, TSS and chemical usage. The device exerts control in areas up to 1,600 feet in diameter.

The buoy provides a complete overview of water quality by collecting data on chlorophyll, blue-green algae, pH, turbidity, dissolved oxygen and temperature every 10 minutes. The collected data is delivered in real time via radio, GPRS or 3G to web-based software. The ultrasonic transmitters are activated and optimized based on the received information.

The ultrasound creates a sound layer in the top sector of the water, keeping algae from rising to the surface to get sunlight. The algae then sink to the bottom as is degraded by bacteria. Visit www.lgsonic.us.
