Last week, the Dutch algae treatment company, LG Sonic installed two solar-powered algae control systems in Coatesville reservoir in Pennsylvania. The Coatesville reservoir is managed by a utility subsidiary of American Water, America’s largest publicly traded water and wastewater utility company. This is the third cooperation project between LG Sonic and American Water, where solar-powered devices are installed to control algae with specific ultrasonic sound waves in drinking water reservoirs. LG Sonic and American Water are also running projects in Hawaii and New Jersey.
A combination of high temperatures stagnant water and nutrient overload can result in excessive algae growth. Causing a depletion of oxygen in the water, release of toxins and taste/odor problems. To successfully control algae in large water surfaces, LG Sonic has developed the solar-powered MPC-Buoy system. The system transmits specific ultrasonic waves based on real-time water quality to target the algae present. This way the system provides a long-term and environmentally friendly algae control solution. In April 2017, two MPC-Buoy systems were installed in the 55 acres Coatesville reservoir in Pennsylvania to control algae growth. The reservoir is used as source for drinking water.
Official Innovation Partner of American Water
In 2014 four MPC-buoys were installed in Reservoir No. 1 at the Canoe Brook Water Treatment Plant in Short Hills, N.J., which is operated by American Water’s New Jersey subsidiary, New Jersey American Water. Extensive testing showed that the MPC-Buoy systems had a significant impact on the algae, allowing the treatment plant to reduce chemical consumption by more than 20%. Based on the results of this study, LG Sonic became an official certified innovation partner of American Water. Together with American Water, LG Sonic is looking to treat other reservoirs impacted by algae including clarification basins, waste backwash lagoons and wastewater/reuse applications. In March 2015, American Water and LG Sonic received a Business Achievement Award from Environmental Business Journal (EBJ) for this cooperation.
Monitor and Control Algae With the MPC-Buoy
The MPC-Buoy is a solar-powered system that combines continuous online water quality monitoring, web-based software, and ultrasonic technology to effectively control harmful algal blooms in large water surfaces, such as lakes and drinking water reservoirs. At this moment, the MPC-Buoy is installed in lakes and water reservoirs in, among other countries, the United States of America, Canada, Singapore, New Zealand, and the United Kingdom.
