American Water Partners with LG Sonic to Monitor, Control Algae Blooms

American Water has announced it has formed a partnership with LG Sonic to perform ultrasonic algae control in water treatment plants. This partnership is a result of the company?s Innovation Development Process, which drives innovation and supports the development of new products.

?This project proved to be a great example of how American Water is committed to protecting the environment, and to finding ways to use our most precious resource wisely,? said Dr. Mark LeChevallier, Director of Innovation and Environmental Stewardship. ?As a leader in researching and deploying water industry innovations, American Water is committed to using technologies that help us increase our efficiencies and the value of the water services we provide to our customers.?

LG Sonic is the first European company to become a Certified Innovation Partner of American Water. ?We are really proud to partner with American Water, the largest and most innovative water utility in the USA. Their philosophy and knowledge of the local market matches our growth ambitions,? said Yousef Yousef, General Manager, LG Sonic. ?

The company?s solar-powered ultrasonic algae control buoys, called the MPC-Buoy, transmit ultrasonic waves continuously to disrupt algal cells, causing them to sink and preventing proliferation. Four of these buoys were recently 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.

This was the first installation of this technology for drinking water reservoirs in North America. This new system combines continuous online water quality monitoring, web-based software and ultrasound technology to better prevent taste and odor events from occurring. Additionally, in keeping with American Water?s sustainability efforts, this system operates 100 percent on solar power and the technology will not harm fish or other wildlife.

Extensive testing conducted during 2014 showed that the buoys had a significant impact on the algae, allowing the plant to reduce chemical consumption by more than 20 percent, and reducing the concentration of undesirable taste and odor causing compounds in the treated water delivered to customers.

Based on the results of this study, American Water plans to purchase buoys for other reservoirs impacted by algae and is looking at other uses including, clarification basins, waste backwash lagoons and wastewater/reuse applications.

This partnership is a product of the company?s Innovation Development Process. Formed in August 2009, American Water?s Innovation Development Process is an initiative that leverages the company?s position and expertise as the nation?s largest water and wastewater services provider to develop innovations by performing idea validation tests using the company?s large and geographically diverse footprint, ultimately becoming an early adopter of new technologies for industry use. It combines American Water?s research and development acumen, technical expertise and infrastructure assets, with innovations from within the company and from business partners, to create greater efficiencies in the areas of water reuse, desalination, wastewater operations and bio-energy.
