Title
(EN) FILTER AND PROCESS TO PREPARE THE SAME
(FR) FILTRE ET PROCÉDÉ DE PRÉPARATION DE CELUI-CI
Abstract
(EN)
The present invention relates to filters, particularly for filtration of water under gravity and to a process for making such filters. The invention also relates to a gravity filtration device using the filter of the invention. It is thus an object of the present invention to provide for a moulded filter that is more reliable and is prone to fewer leaks as compared to similar types of prior art filters. A filter comprising a filter block comprising particulate filter media and polymeric binder having melt flow rate less than 5 grams/10 minutes; and an end plate integrally moulded to said filter block, said end plate having a port for passage of liquid and made of a polymer having a melt flow rate less than 5 grams/10 minutes.

L'invention concerne des filtres, en particulier pour la filtration de l'eau par gravité, et un procédé de fabrication de tels filtres. L'invention concerne également un mécanisme de filtration par gravité utilisant le filtre de l'invention. Le but de l'invention est de réaliser un filtre moulé plus fiable et moins sujet aux fuites que des types similaires de filtres de l'art antérieur. Un filtre comprenant un bloc filtrant comprenant un support filtrant constitué de particules et un liant polymère ayant un coefficient de fluage inférieur à 5 grammes/10 minutes ; et une plaque d'extrémité moulée intégralement audit bloc filtrant, ladite plaque d'extrémité comportant un orifice pour le passage de liquide et fabriquée à partir d'un polymère ayant un coefficient de fluage inférieur à 5 grammes/10 minutes.
