According to a case study, the cooling towers achieved a 69 percent reduction in biocide dosage and up to a 53 percent reduction in anti-scalant dosage after Al Futtaim Cooling district plant incorporated LG Sonic’s ultrasonic algae control into its chemical water treatment program.
Earlier this year American Water formed a partnership with LG Sonic to perform ultrasonic algae control in water treatment plants.
LG Sonic’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, New Jersey, 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, this system operates 100 percent on solar power and the technology will not harm fish or other wildlife.
