Algal blooms are a form of pollution that can harm water quality and increase operating costs at treatment plants due to the presence of toxic algae. These toxins are complex, odorless, and resistant to sterilization. To meet legal requirements and optimize costs, it is essential to control algal growth in treatment plants using surface water for drinking.
One solution for controlling algae is ultrasound technology, which uses sound waves at a resonant frequency to disrupt the structure of the cells. This can sink blue-green algae and disrupt their life cycle, or affect the inner cell membrane of other types of algae, causing it to separate from the outer membrane.
