Abstract (en)
[origin: WO2005115925A1] The invention relates to a pure water treatment method. According to the invention, once ultra-pure water has been obtained, it is treated by means of cavitation in a tank that is equipped with an acoustic antenna (3) comprising Tonpilz-type piezoelectric transducers which emit at least at the excitation frequency of the water molecules with a sound power that enables the cavitation threshold to be exceeded, taking account of the quantity of water to be treated.
