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 attack cells of parasites as well as biofouling and depending on various circumstances


Through years of research, a team of Dutch technicians, researchers and scientists developed a system that targets to minimalize parasites, algae, bacteria, seed mussels, barnacles and more. This technology is based on the generation of Nano cavitation, which stimulates the implosion of microscopic vacuum bubbles, created by the resonators.

The technology of ultrasound is proven to be effective by various laboratories / researches. Our company is aiming to use this technology on larger scale in different applications. In the short existence of our company there were positive results in different applications in different parts of the world, however in some cases we didn’t get the wanted results. It’s yet unclear which adjustments need to be made according to all circumstances and applications.

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 bacteria, algae and biofouling are attacked. At frequencies of between 35 and 60 KHz, parasites that are 0.2 mm to 0.7 mm in size, are attacked as well. The vibrations created by the resonator are enhanced by nano-cavitation.
