Investigations dealing with the treatment of aqueous systems by physical methods show that ultrasound is an effective reagentless and highly ecological method of water purification of organic pollutants and microorganisms. Its use is particularly effective in combined methods of treatment: ultrasound + ultraviolet irradiation; ultrasound + ultraviolet + ozonization; ultrasound + hydrogen peroxide; ultrasound + Fenton’s reagent, etc. In many cases the combined techniques make it possible to achieve better purification results due to a synergistic effect. The most promising techniques involve the application of high frequency ultrasound (200–500 kHz), simultaneous ultrasound treatment with two frequencies, and the use of hydrodynamic cavitators.
