Title
(EN) A PROCESS FOR MAKING A FILTER BLOCK CUM SEDIMENT FILTER
(FR) PROCÉDÉ DE FABRICATION D'UN BLOC DE FILTRATION COMPORTANT UN FILTRE À SÉDIMENTS
Abstract
(EN)
The present invention relates to a process for making a filter block cum sediment filter, suitable for use in gravity-fed filtration units, which provides for filtering particulate contaminants and also have relatively high flow rates and life. According to another aspect,the present invention relates to filter blocks cum sediment filter obtained by such process. It is an object of present invention to provide a bound filter block with a sediment filter integrally fitted on its outer surface for use in gravity-fed filtration units. It has been found that when a hemispherical carbon filter block having a sediment filter integrally fitted to its external surface is used for removal of particulate contaminants in the gravity fed-filtration devices,it provides relatively high flow rates and enhanced life.

La présente invention concerne un procédé de fabrication d'un bloc de filtration comportant un filtre à sédiments, approprié pour une utilisation dans des unités de filtration alimentées par gravité, qui assure une filtration de contaminants particulaires et a également des débits relativement élevés et une durée de vie relativement élevée. Selon un autre aspect, la présente invention concerne des blocs de filtration comportant un filtre à sédiments obtenus par un tel procédé. Un objectif de la présente invention est de fournir un bloc de filtration lié, un filtre à sédiments étant intégralement adapté sur sa surface externe pour une utilisation dans des unités de filtration alimentées par gravité. Il a été découvert que, lorsqu'un bloc de filtration à carbone hémisphérique ayant un filtre à sédiments intégralement adapté sur sa surface externe est utilisé pour l'élimination de contaminants particulaires dans les dispositifs de filtration alimentés par gravité, il fournit des débits relativement élevés et une durée de vie augmentée.
