Title
(EN) CARRIER LIQUID FILTRATION UTILIZING ELECTRIC FIELDS
(FR) FILTRATION DE LIQUIDE PORTEUR À L'AIDE DE CHAMPS ÉLECTRIQUES
Abstract
(EN)
In an example of the disclosure, carrier liquid is supplied to a container with a set of walls defined at least partially by a surface of an electrode. The carrier liquid is caused to move through a container via a carrier liquid flow path to sequentially encounter a set of accumulation elements. Each accumulation element is situated between adjacent walls. A voltage is applied to the electrode to generate an electric field between the electrode surface and the set of accumulation elements. The electric field causes contaminant from the carrier liquid to adhere to the set of accumulation elements.
(FR)
Dans un exemple de la présente invention, un liquide porteur est fourni dans un récipient ayant un ensemble de parois qui sont définies au moins partiellement par une surface d'une électrode. Le liquide porteur est amené à se déplacer à travers un récipient par l'intermédiaire d'un trajet d'écoulement de liquide porteur pour rencontrer de manière séquentielle un ensemble d'éléments d'accumulation. Chaque élément d'accumulation est situé entre des parois adjacentes. Une tension est appliquée à l'électrode pour générer un champ électrique entre la surface d'électrode et l'ensemble d'éléments d'accumulation. Le champ électrique provoque l'adhérence des contaminants se trouvant dans le liquide porteur à l'ensemble d'éléments d'accumulation.
