The dominant blue-green algae were Cylindrospermopsin and Microcystis, requiring frequent use of Copper Sulfate treatments to reduce the algae prior to the treatment plant. Ultrasound just as effective in controlling the algae Reservoir is clearer than it has been historically Overall lower cyanobacteria count
WILMINGTON OH – Eliminating Copper Sulphate
AQUARION – Reducing need for chemical treatments
The goal for utilizing ultrasound in the North Stamford, Putnam and Mianus reservoirs was to reduce the need for copper sulphate treatments to take care of a blue-green algae issue. Positive effective on delaying blue-green algae blooms Reduced chemical consumption Improved water quality
