Small Investments in Diffused Aeration and Ultrasound Systems Make Big Improvements in Water Quality

At a Syracuse, New York-area reservoir the use of two technologies—diffused aeration systems and ultrasonic algal control—reduced the need to mitigate algae through use of costly chemical algaecides. The payback period of these two technologies was less than two years.

We needed to consider a more sustainable solution to mitigate the growing algal cell counts at the reservoir and eliminate the costly and labor-intensive applications of copper sulfate.”
