In the Algae Bluster there are two parts:
An electronic power box generates sound pulses. Because of the technology used in the power box, it is possible to generates several different frequencies simultaneously and send them to transducer.
The ultrasonic transducer is placed in the pond or lake in a positioned, just below and horizontal to the surface of water. It emits these different ultrasound frequencies into the water. When these high frequency pulses hits algal cells, the cells begins to oscillate with these frequencies. If the algae, has a gas vacuole, then this vacuole also starts to oscillate with resonating frequencies to such an extent that it continues to increase in size. Then there comes a point when the vacuole becomes unstable and breaks down, making the algae sink to the bottom of the pond. Algal species which don't have gas vacuoles react differently. The vibrations from the ultrasound cause the inner cell wall of the algal cell to become separated from the outer cell wall this means that water, gases and nutrients can neither be absorbed nor expelled and as a result the algae dies. The pictures below demonstrate the effect of ultrasound on the cell structure of Spirogyra as mentioned above. It can clearly see how the plasmalemma becomes separated from the outer cell wall.
Sound pulses are being generated within the power box. The power box generates several different frequencies simultaneously and sends them to the transducer.
The transducer transmits these sound pulses into the water with a very high sound pressure (dB). The sound waves have different frequencies but all lie in the ultrasound range and are thus inaudible.
The high pressure ultrasound emitted by the AlgaeBluster targets many different algae structures. Components of algae cells, within the long range of AlgaeBluster, oscillate on the sound frequencies. This leads to tearing of different cell organelles such as the cell wall or membrane and the gas vesicles of algae. Because of many frequencies are used simultaneously different species of algae can be controlled.
