A method of manufacturing ceramic filter media for water filters involves the steps of mixing a plurality of raw ceramic materials and a plurality of extrusion- aid materials to form a mixture of constituent materials, extruding the constituent materials to form tubular filter media, drying the tubular filter media, and firing the tubular filter media to create ceramic tubular filter media. The step of drying the tubular filter media preferably comprises placing the tubular filter media on top of rotating rollers which dries the tubular filter media evenly and preserves the desired characteristics of the tubular filter media.
L'invention porte sur un procédé de fabrication de matériaux céramiques filtrants pour filtres à eau (26) consistant à mélanger plusieurs matières premières de céramique et plusieurs matériaux d'aide à l'extrusion de manière à obtenir un matériau constitutif qui est extrudé sous forme de tube (26) puis cuit pour donner un filtre céramique tubulaire (26). Le séchage du matériau filtrant tubulaire (26) s'opère de préférence en le (26) plaçant sur des cylindres tournants (62) qui en assurent le séchage régulier et en préservent les caractéristiques de filtrage désirées.
