Abstract
(EN) The present document pertains to the fields of mechanical engineering and chemistry, and is specifically directed to a device and system for filtering fluids using the combined action of mechanical filtration, by retention of particulate in a mesh, and chemical filtration, by adsorption of microplastic particulate on iron oxide, particularly magnetite. In one embodiment of the invention of the present document, the filtration device is applied in-line in the outlet of a domestic washing machine, in-line in the outlet of a commercial washing machine, in-line with a sink trap, instead of the sink trap, in the outlet of a sewage system, and as a filter element for assisting in the cleaning of effluent contaminated with particulate. The device of the present invention is capable of retaining microplastics in the 5 μm to 100 μm range.
(FR) La présente invention concerne les domaines de l'ingénierie mécanique et de la chimie, spécifiquement un dispositif et un système de filtrage des fluides utilisant l'action combinée du filtrage mécanique par piégeage de matière particulaire sur un tamis, et du filtrage chimique, par adsorption de particules microplastiques en oxyde de fer, notamment de la magnétite. Dans un mode de réalisation de la présente invention, le dispositif de filtrage est utilisé en ligne à la sortie de la machine à laver domestique, en ligne à la sortie de machine à laver industrielle, en ligne avec un siphon de lavabo, en substitution au siphon du lavabo, dans la sortie du réseau d'assainissement, et comme élément de filtrage auxiliaire au nettoyage des effluents contaminés avec des particules. Le dispositif de la présente invention permet de retenir les microplastiques de dimension allant de 5 μm à 100 μm.
