| Research Abstract |
The ballast water treatment technology was developed using mechanochemical cavitation provided by ejector nozzles. An extinction ratio of 100% was achieved, when the flow rate is set to 30 L/min. The superimposed effect of processing performance to Artemia salina and marine organisms was recognized by mechanical effect due to cavitation collapse and chemical effect in the mechanochemical cavitation. The chemical action to marine organism was enhanced by chemical microcavitation. It was found that the chemical microcavitation has an effect drawing plankton to cavitation by visualizing the interaction between cavitation and plankton.
