Abstract

An experimental cavitation equipment was designed, built and applied on a small scale to investigate a possible method of purifying contaminated water. The experimental unit is mobile and suitable for the purification of water with different contaminations. The effect of cavitation on organisms of different microscopic sizes is demonstrated. First, a diluted culture of green algae was tested and it was found that 16–
32 minutes of cavitation reduced chlorophyll concentration and intact cell percentage by more than 10–20%. In fishpond water mixed with biodegradable wastewater, cavitation reduced cyanobacteria and flagellate algae by 40–80%, with minimal reduction in green algae. For this purpose a flat type HP cavitation generator has been used. Evidence has been provided that cavitation water treatment is a promising solution for reducing the microbiota in ships’ ballast water and wastewaters, but care must be taken to ensure that the microbiota is only destroyed, but not removed from the water.
