Title (EN) METHOD AND APPARATUS FOR APPLYING ELECTRICAL CHARGE THROUGH A LIQUID HAVING ENHANCED SUSPENSION PROPERTIES
(FR) PROCÉDÉ ET APPAREIL D'APPLICATION D'UNE CHARGE ÉLECTRIQUE À TRAVERS UN LIQUIDE POSSÉDANT DES PROPRIÉTÉS DE SUSPENSION AMÉLIORÉES
Abstract:
(EN) An apparatus (10, 50, 80, 300, 500, 1200, 1300, 1400, 1500,1700, 1810) and method are provided. The method includes for example, treating a liquid in an apparatus to increase suspension properties of the liquid and dispensing the treated liquid (250, 302, 306, 308, 1414, 1504, 1917) from the apparatus to a surface or volume of space (252, 304, 1506) so as to create an electrically conductive path by the treated liquid from the apparatus to the surface or volume of space. During the step of dispensing, an alternating electric field (E) is generated from the apparatus to the surface or volume of space, through the liquid along the conductive path, wherein the electric field is sufficient to destroy at least one microorganism (256) from the surface or in the volume of space.
(FR) L'invention porte sur un appareil (10, 50, 80, 300, 500, 1200, 1300, 1400, 1500,1700, 1810) et sur un procédé. Le procédé comprend, par exemple, le traitement d'un liquide dans un appareil afin d'augmenter les propriétés de suspension du liquide et délivrer le liquide traité (250, 302, 306, 308, 1414, 1504, 1917) depuis l'appareil jusqu'à une surface ou volume d'espace (252, 304, 1506) de façon à créer un trajet conducteur de l'électricité au moyen du liquide traité de l'appareil à la surface ou volume d'espace. Durant l'étape de délivrance, un champ électrique alternatif (E) est généré par l'appareil et appliqué à la surface ou volume d'espace par le liquide selon le trajet conducteur, le champ électrique étant suffisant pour détruire au moins un microorganisme (256) sur la surface ou dans le volume d'espace.
