How it started

The process of controlling algae through vibrations has been around for quite a while. Long ago, it started with using small loudspeakers to generate ultrasonic sound waves. The vibrations generated would severely disturb the cells of the algae and, ultimately, eliminate them.

However, this technology did not appear powerful enough to control algae and other organisms. Most ultrasonic systems operate on 40 kHz at 50 dB. Their operation is based mostly on converting electric energy into mechanical energy.

Kinetic energy

Our resonators operate on a frequency of 40 kHz at no less than 110 dB. As the decibel scale is logarithmic, the difference in power compared to other systems is huge.

The H2O technology produces more than 40,000 vibrations per second that convert the mechanical energy in the water into kinetic energy. The pulses are much stronger than those of traditional systems. The result is large scale Nano cavitation, up to 55 meters in salt water and 40 meters in fresh water. Nano cavitation is microscopically small and yet 100 times more powerful than ultrasound on its own.

Water jets

Nano cavitation is the phenomenon where, due to a drop in pressure, bubbles are generated in the water that subsequently implode when this pressure is increased. The water surrounding the bubbles is, as it were, drawn into the implosion and produces microscopic water jets under very high pressure. These water jets eliminate the cells of the parasites that are being combated, as well as biofouling.


Through years of research, a team of Dutch technicians, researchers and scientists managed to develop a powerful system; one that eliminates, parasites, algae, bacteria, seed mussels, barnacles and more. This revolutionary technology is based on the generation of Nano cavitation, which stimulates the implosion of microscopic vacuum bubbles, created by resonators. As far as is known, H2O Technics is the only company in the world supplying this type of product, which justifies it being referred to as revolutionary.

Frequency range

The vibrations generated by H2O products cover a frequency range of 20 to 60 KHz, where 40 KHz is the main frequency. At a frequency of between 20 and 45 kHz, various species of algae are destroyed. At frequencies of between 35 and 60 KHz, parasites that are 0.2 mm to 0.7 mm in size, are destroyed as well. The vibrations created by the resonator are enhanced by Nano cavitation.
