In a liquid treating process according to the present invention, colloidal particles in stable hydrated states or in meta-stable hydrophobic colloidal states in a liquid are rendered hydrophobic and separated from liquid molecules by an electric field formed by a microwave. The separated colloidal particles are allowed to collide against one another to become flocculated under a cavitation effect by a ultrasonic wave having a frequency in a low frequency range, and the liquid is deodorized by an electromagnetic ultrasonic wave having a frequency in a high frequency range. Therefore, it is possible to easily and reliably remove the colloidal particles dissolved in the liquid and to deodorize the liquid without need for a large-scaled equipment. For this purpose, the microwave which is an electromagnetic wave is emitted to the liquid containing the colloidal particles of water-soluble organic substances, microorganisms and the like to separate the colloidal particles from the liquid molecules and then, a ultrasonic wave having a frequency in a low frequency range is emitted to the liquid resulting from the separation of the colloidal particles to flocculate the colloidal particles, and an electromagnetic ultrasonic wave having a frequency in a high frequency range is emitted to the liquid to deodorize the liquid.
Un procédé de traitement d'un liquide consiste à rendre hydrophobe des particules colloïdales dans un état hydraté stable ou un état colloïdal hydrophobe métastable dans le liquide à l'aide d'un champ électrique formé par une micro-onde, afin de les séparer des molécules du liquide, à faire entrer en collision les particules colloïdales séparées les unes avec les autres par l'action de cavitations provoquées par des ultrasons basse fréquence afin de coaguler les particules, et à désodoriser le liquide avec des ultrasons électromagnétiques à haute fréquence. Ainsi, les particules colloïdales dissoutes dans le liquide peuvent être extraites facilement sans faille et le liquide peut être désodorisé sans installations à grande échelle. Spécifiquement, on traite un liquide contenant des particules colloïdales de substances organiques hydrosolubles, des micro-organismes etc., par application d'une micro-onde au liquide afin de séparer les particules colloïdales des molécules du liquide, puis par application d'ultrasons basse fréquence au mélange obtenu afin de coaguler les particules colloïdales et enfin par application d'ultrasons électromagnétiques à haute fréquence au liquide afin de le désodoriser.
