Abstract
This is a first report of the use of cavitation treatment, an innovative method, to suppress phytoplankton biomass. It was found that cavitation treatment immediately kil1ed some algal cells in pond waters; about 75% of Peridinium sp. died when exposed to cavitation for one minute at 1800 rpm of the shaft rotation in a cylinder. The effectiveness of cavitation for causing algal death varied with different species. These results showed the possibility of using cavitation treatment to suppress algal biomass for a short time. Experiments combining different cavitation powers and treatment times with different species are required if we are to develop an effective system for suppressing specific algal blooms in particular bodies of water.
