Ultrasonic Algae Control

Defend against algae, without chemicals, using ultrasonic technology that is not harmful to the environment and requires no continuous applications.

How it works

The transducer, submerged just beneath the surface of the water, is programmed to generate varying frequencies in a linear pattern covering up to 120 surface acres. Different frequencies affect different types of algae.  This ensures algae cannot rise to the surface, restricting access to photosynthesis, causing the organism to die.

How ultrasound works on algae

Sound waves cause the gas vacuoles to collapse, deflating them, inhibiting their ability to float to stay alive.  They traverse low in the water column beyond the reach of sunlight and starve to death.  The cell does not burst, toxins remain contained within the cell, avoiding the release of toxins into the water. The dead algae, along with the toxins they contain are consumed by fish and naturally occurring bacteria. 

Ultrasound and Biofilm

Biofilm creates a slime layer and adheres to a surface and coats itself with a polysacchardie layer.  This layer is porous allowing the cells to get nutrients and expel waste.  Biofilm does not like water current or movement, this is how ultrasound can help fight biofilm.  The frequencies of ultrasound create a perception of turbidity to help stop the colonization of biofilms and sludge from accumulating.  

Critical structural resonance

Ultrasonic transducers create an environment of unsuitability for bioorganisms through the use of sound pressure frequencies meant to produce critical structural resonance (CSR), that impacts cyanobacteria, chlorophyta, diatoms and biofilm.  The vast bandwidth of frequencies allows ultrasound to target the variety of algae types, size and shape. Exposure to these sounds cause the cell membranes of these critical life functions to break or tear.  Once torn, the life cycle of the algae cells are disrupted resulting in death.  Similar to the opera singer breaking a wine glass when they hit the perfect note.  It is the note getting closer to the wine glass’ CSR…same affect of ultrasonic on algae!
