| Abstract: | Hydrodynamic cavitation has been a potential technology of water treatment. By collecting cavitation noise signal with hydrophone and analyzing comparatively the features of power spectrum of cavitation noises produced by different nozzles, it is obtained that the choking cavitator has a flat roof in power spectrum curve which is a broadband and high energy. So the choking cavitator is suitable especially for hydrodynamic cavitation treating waste water and purifying water. |
