Abstract

Le problème décrit par la présente invention est d'obtenir une eau potable conforme à une norme de qualité d'eau en faisant appel à de l'eau telle que des eaux fluviales, des eaux souterraines, des eaux lacustres, des eaux de citernes, des eaux stockées, ou de l'eau de mer disponibles comme eaux brutes dans un cas tel que lorsque l'alimentation en eau du robinet est coupée en raison d'une catastrophe à grande échelle ou similaire. La solution selon l'invention porte sur un purificateur d'eau qui est conçu à partir : d'un récipient formant corps cylindrique (10) ; d'un couvercle supérieur (11) du récipient formant corps (10) ; d'une base inférieure (12) du récipient formant corps (10) ; et d'une unité support de filtre (20) comprenant une membrane d'ultrafiltration constituée de résine de polystyrène, d'une feuille de charbon actif comprenant un textile intissé de fibres de charbon actif enroulée autour de la périphérie externe de la membrane d'ultrafiltration, et d'un filtre à sédiments comprenant du polypropylène enroulé autour de la périphérie externe de la feuille de charbon actif ; l'unité support de filtre (20) étant logée/disposée dans un seul récipient formant corps cylindrique (10), et un passage pour l'eau relié à un orifice d'entrée d'eau brute et à une sortie d'eau purifiée étant commuté par une opération de rotation prédéfinie d'une partie tête prévue sur le passage pour l'eau.
