CyanoStop

Combats cyanobacteria 

In other countries, various studies have been performed and tests carried out to determine the effectiveness of combating cyanobacteria with ultrasound, and the results have been positive. On pages 26 and 27 of a literary study by the University of Utrecht, called “ultrasound as a method of sterilisation” the conclusion is also made that algae and bacteria can effectively be combated using ultrasound.

Tests were also performed in the Netherlands, but with non-cavitation equipment. According to the scientific reports analysed in the Utrecht literary study, this cannot work.

In the fight against cyanobacteria, ultrasound is best put to use on a preventative basis. Ultrasound treatment implemented once the cyanobacteria are already present en masse, has a reverse effect. This is because cyanobacteria release toxic substances such as cyanide, as well as microcystins and neurotoxins.

Ultrasound has major advantages in relation to other methods of prevention. Because ultrasound is a mechanical prevention method, there will be no problems with increased resistance. Neither will any hazardous chemical substances (residue) remain in the water.

A study ordered by the Rijnland district water board has shown that fish suffer no ill effects from the use of ultrasound.

A literary study by the Rijkwaterstaat has indicated that ultrasound is a possible solution in the fight against cyanobacteria.
