Title (EN) REMOVAL OF BACTERIA FROM DRINKING WATER VIA FILTRATION
(FR) ELIMINATION DE BACTÉRIES DE L'EAU POTABLE PAR FILTRATION
(DE) ENTFERNUNG VON BAKTERIEN AUS TRINKWASSER ÜBER FILTRATION
Abstract:
(EN) The present invention relates to a method for producing biocidal, porous particles of a cross-linked polymer, and to the porous particles that can be produced according to the method of the invention. The invention further relates to porous particles of an amino-group-containing polymer (polyamine) having a relatively low swelling factor. The porous particles according to the invention are used to remove biological contaminants from water and to bind metal-containing ions from solutions. The present invention further relates to a filter cartridge which contains the porous cross-linked polymer particles according to the invention.
(FR) L'invention concerne un procédé de fabrication de biocides, des particules poreuses réalisées dans un polymère réticulé, et les particules poreuses elles-même qui sont fabriquées selon l'invention. L'invention concerne également des particules poreuses réalisées dans un polymère contenant des groupes amino (polyamine) ayant un facteur de gonflement relativement faible. Les partricules poreuses selon l'invention, sont utilisées pour éliminer les impuretés biologiques contenues dans l'eau et pour lier des ions métallifères de solutions. L'invention concerne également une cartouche filtrante qui contient les particules poreuses selon l'invention réalisées dans un polymère réticulé.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von bioziden, porösen Partikeln aus einem vernetzten Polymer, und die porösen Partikel selbst, die nach dem erfindungsgemäßen Verfahren herstellbar sind. Weiterhin betrifft die vorliegende Erfindung auch poröse Partikel aus einem Amino-Gruppen enthaltenden Polymer (Polyamin) mit einem relativ geringen Quellfaktor. Die erfindungsgemäßen porösen Partikel werden zur Entfernung von biologischen Verunreinigungen aus Wasser sowie zur Bindung von Metallhaltigen Ionen aus Lösungen verwendet. Die vorliegende Erfindung betrifft auch eine Filterkartusche, die erfindungsgemäße poröse Partikeln aus einem vernetzten Polymer enthält.
