Abstract

A filter cartridge for filtering liq. comprises a first filter surface for retaining solid particles from the liq. being filtered and a particulate filter bed to absorb or adsorb the contaminants not retained by the first filter surface, and has a second filter surface bounding the bed downstream in the direction of flow of the liq. being filtered. The second surface is pref. constituted of paper folded to increase the filter surface. The invention provides a structure having a high filtering power, preventing the escape of particles from the filter bed and allowing the use of a downstream perforated cylinder with much larger holes than in existing cartridges, reducing the cost of fabrication and the rate of blockage of the upstream filter paper.
